How to Free Up Disk Space on Windows Without Deleting Important Files

Darkssel — Mon, 24 Aug 2026 18:51:46 +0000

You open File Explorer.

You see a red bar on your C: drive.

You hover over it:

"15.2 GB free of 237 GB."

Your PC is running slow. Apps take forever to open. Windows is warning you about low disk space.

You think:

"What can I delete? What's safe to remove? What if I delete something important?"

You're not alone.

This is one of the most common Windows problems — and one of the most stressful.

The good news?

You can free up gigabytes of space without deleting anything important.

This guide walks you through 10 safe methods to clean your C: drive — from built-in Windows tools to advanced tricks.

Let's go.

1. Run Disk Cleanup (Including System Files)

Disk Cleanup is Windows' built-in disk-cleaning tool. It's safe, effective, and often recovers several gigabytes.

How to run it:

Press Win + R, type cleanmgr.exe, and press Enter
Select your C: drive and click OK
Click Clean up system files (this is where the real space is)
Select C: again and wait for the scan
Check these boxes:
- Windows Update Cleanup (often GBs)
- Temporary files
- Recycle Bin
- Delivery Optimization Files
- Previous Windows installations
- Temporary Windows installation files
- Thumbnails
Click OK → Delete Files

What you gain: Often 5–20 GB or more, especially if you've never run it before.

2. Turn On Storage Sense (Automatic Cleanup)

Storage Sense automatically deletes temporary files, clears the Recycle Bin, and removes old Downloads folder items on a schedule.

How to enable it:

Open Settings → System → Storage
Turn Storage Sense to On
Click Storage Sense to configure:
- Run it daily, weekly, or monthly
- Delete files in Recycle Bin after 30 days (or sooner)
- Delete files in Downloads after 30 days (if you want)

Pro tip: Storage Sense runs in the background — set it and forget it.

3. Use Cleanup Recommendations

Windows 11 also provides a Cleanup recommendations section that shows you exactly what's taking up space.

How to use it:

Settings → System → Storage
Click Cleanup recommendations
Review categories:
- Temporary files
- Large or unused files
- Files synced to the cloud
- Unused apps
Select items to remove and click Clean up for each section

What's nice: It shows you the size of each item before you delete it.

4. Delete Temporary Files Manually

Windows stores temporary files in several locations. Many of these files can be safely removed, although some may still be in use.

Locations to clean:

Press Win + R, type %temp%, press Enter → select files you no longer need and delete them
Press Win + R, type temp, press Enter → select files you no longer need and delete them

Note: Windows may refuse to delete files that are currently in use. Simply skip those files and continue.

What you gain: Usually 1–5 GB, depending on your usage.

About Prefetch: I generally don't recommend clearing the Prefetch folder (C:\Windows\Prefetch). It stores data that helps apps launch faster, and clearing it usually frees very little space while potentially slowing down app launches temporarily.

5. Remove Old Windows Update Files

Windows keeps old update files so you can uninstall updates if needed. These are safe to remove if your system is stable.

How to remove them:

Via Disk Cleanup: Run cleanmgr.exe → Clean up system files → check Windows Update Cleanup
Via Storage Settings: Settings → System → Storage → Temporary files → check Windows Update Cleanup → Remove files

Important: In some Windows 11 versions (25H2+), Windows Update Cleanup may not appear in the list. If you don't see it, use Disk Cleanup as Administrator instead.

What you gain: Often 3–10 GB.

6. Uninstall Unused Apps

You've probably installed apps you never use. They take up space.

How to check:

Settings → Apps → Installed apps
Sort by Size (largest first)
Review apps you don't use
Click Uninstall for each

What to look for:

Games you no longer play
Old Adobe apps
Trial software
Bloatware that came with your PC

What you gain: Varies — some games are 50+ GB.

7. Move Personal Files to Another Drive

Your Documents, Pictures, Music, and Videos folders often contain large files that don't need to be on C:.

How to move them:

Settings → System → Storage → Advanced storage settings
Click Where new content is saved
Change each category (Documents, Music, Pictures, Videos) to another drive

Alternatively: Manually move large folders to an external drive or a second internal drive.

What you gain: Varies — could be tens of gigabytes.

8. Use a Disk Space Analyzer (Find Large Files)

Sometimes the biggest space hogs are hidden in folders you never think to check.

Disk space analyzers scan your drive and show you exactly where space is being used.

Best free tools:

Tool	Description
WizTree	Fastest — reads NTFS MFT directly, scans in seconds
WinDirStat	Classic open-source tool with treemap visualization
TreeSize Free	Popular, shows folder sizes in a clean interface

How to use:

Download and run as Administrator
Select your C: drive
Wait for the scan (seconds with WizTree, minutes with WinDirStat)
Look for large files or folders you can delete or move

Pro tip: WizTree is the fastest — it scans a 1TB drive in seconds.

9. Disable Hibernation (If You Don't Use It)

The hibernation file (hiberfil.sys) can be several gigabytes — roughly the size of your RAM.

If you never use Hibernate (you use Sleep or Shutdown instead), you can safely disable it and reclaim that space.

How to disable hibernation:

Open Command Prompt as Administrator
Run: powercfg /h off
Windows removes the hibernation file when you disable hibernation.

Note: This disables Hibernate and Fast Startup. Sleep and normal shutdown still work.

What you gain: 1–32 GB, depending on your RAM size.

10. Enable OneDrive Files On-Demand

If you use OneDrive, Files On-Demand keeps only placeholders on your local drive. Full files are downloaded only when you open them.

How to enable:

Right-click OneDrive icon in system tray
Select Settings → Sync and backup
Under Files On-Demand, make sure it's enabled

What you gain: Varies — can free up gigabytes if you have large cloud files.

What NOT to Delete (Safety First)

Don't Delete	Why
Windows folder	Critical system files
Program Files	Installed apps (uninstall properly instead)
System Volume Information	System restore points
Pagefile.sys	Virtual memory (Windows manages it)
Files you don't recognize	Research first

Golden rule: If you're unsure, don't delete it. Use the built-in tools instead.

What If You Want to Monitor Your Windows PC Automatically?

Freeing up disk space solves one problem, but it doesn't tell you what's happening on your PC afterward.

If you want to keep an eye on things like new processes, startup changes, USB connections, CPU/RAM anomalies, and Windows Defender status, automatic monitoring can make that easier.

That's why I built SysPulse, a lightweight Windows security and monitoring tool.

SysPulse can:

Detect new processes and show their full paths
Monitor CPU and RAM anomalies
Detect startup changes
Detect USB connections
Monitor Windows Defender status
Send Telegram notifications for monitored events
Run silently in the background
Use less than 30MB of RAM

You can set it up once and let it monitor your Windows PC in the background.

You can find it at: syspulse.pro

Summary Table

Method	Difficulty	Potential Space
Disk Cleanup	Easy	5–20 GB
Storage Sense	Easy	Automatic
Cleanup Recommendations	Easy	Varies
Delete Temp Files	Easy	1–5 GB
Remove Windows Update Cleanup	Easy	3–10 GB
Uninstall Unused Apps	Easy	Varies
Move Personal Files	Medium	Varies
Disk Space Analyzer	Medium	Varies
Disable Hibernation	Easy	1–32 GB
OneDrive Files On-Demand	Easy	Varies

Final Thought

A full C: drive doesn't mean you need a new PC.

Start with the simplest methods:

Run Disk Cleanup (including system files)
Turn on Storage Sense
Uninstall unused apps

If you need more space, use a disk space analyzer to find large files and move them to another drive.

The result: A faster, cleaner PC with room to breathe — without deleting anything important.

How to Fix Blue Screen of Death (BSOD) in Windows 11 (Complete Guide)

Darkssel — Mon, 24 Aug 2026 10:39:02 +0000

You're working on something important.

Suddenly, the screen freezes.

A blue screen appears with a sad face and a cryptic error code.

Your PC restarts — and you lose everything you were working on.

You might think:

"Did my PC just die? Do I need a new computer?"

No.

The Blue Screen of Death (BSOD) is scary — but it's almost always fixable.

This guide walks you through everything you need to know about BSODs — from understanding error codes to fixing the root cause and preventing future crashes.

What Is a BSOD?

A Blue Screen of Death (also called a Stop Error or system crash) occurs when Windows encounters a critical error it can't recover from.

To prevent data corruption or hardware damage, Windows stops everything and displays a blue screen.

The screen usually includes:

A sad face emoji (😢)
An error code (like CRITICAL_PROCESS_DIED)
A QR code (on newer versions)
Technical information about what went wrong

The good news: Most BSODs are caused by software or driver issues — not hardware failure. And most are fixable without replacing parts.

10 Common Causes of BSOD

Understanding the cause helps you find the right fix.

Cause	Description
1. Faulty or outdated drivers	The most common cause — graphics, network, or chipset drivers
2. Hardware issues	Faulty RAM, failing hard drive, or overheating components
3. Corrupt system files	Windows files damaged by malware, power outages, or updates
4. Malware	Some malware can cause system instability
5. Overclocking	Unstable overclocks can cause crashes
6. Insufficient power	Power supply can't handle the load
7. BIOS/UEFI issues	Outdated or misconfigured firmware
8. Software conflicts	Incompatible applications or services
9. Memory issues	Bad RAM or insufficient memory
10. Disk errors	Corrupted sectors on the system drive

Step-by-Step: How to Fix a BSOD

Step 1: Write Down the Error Code

This is one of the most important steps.

The error code can provide an important clue about what caused the crash.

Where to find it:

On the blue screen itself
Or in Event Viewer after restart:
1. Press Win + R, type eventvwr.msc, press Enter
2. Go to Windows Logs → System
3. Look for errors with Source: BugCheck

Alternative: Use the QR code (if visible) to quickly access Microsoft's troubleshooting page.

Step 2: Boot into Safe Mode

If the BSOD prevents normal boot, enter Safe Mode.

How to enter Safe Mode:

Restart your PC
As soon as the manufacturer logo appears, hold the power button to force shutdown
Repeat 2–3 times until you see "Preparing Automatic Repair"
Click Advanced options → Troubleshoot → Advanced options → Startup Settings → Restart
Press 4 for Safe Mode (or 5 for Safe Mode with Networking)

In Safe Mode:

Windows loads with minimal drivers
You can uninstall problematic drivers or software
You can run scans and diagnostics

Step 3: Uninstall Recent Drivers or Software

If the BSOD started after installing new drivers or software, uninstall them.

How to uninstall a driver:

Open Device Manager (right-click Start → Device Manager)
Find the problematic device (often graphics, network, or chipset)
Right-click → Uninstall device
Check Delete the driver software for this device
Click Uninstall
Restart your PC

How to uninstall software:

Go to Settings → Apps → Installed apps
Find the recently installed app
Click Uninstall
Follow the prompts

Pro tip: If you can't boot normally, do this in Safe Mode.

Step 4: Run Windows Memory Diagnostic

Faulty RAM is a common cause of BSOD.

How to test RAM:

Press Win + R, type mdsched.exe, press Enter
Select Restart now and check for problems
Windows will test your memory on reboot
The scan takes 10–30 minutes
After completion, Windows will show the results

If errors appear: You'll need to replace the faulty RAM stick.

Temporary workaround: If you have multiple RAM sticks, try removing one at a time to identify the bad one.

Step 5: Run Disk Check (CHKDSK)

Disk errors can also cause BSOD.

How to check disk health (recommended first step):

Open Command Prompt as Administrator
Run: chkdsk /scan
This scans the drive without making changes — it's safe and quick

If issues are found, run a repair:

Run: chkdsk /f /r C:
Press Y to schedule the scan
Restart your PC
Windows will scan and repair disk errors during boot

Note: The /f /r scan can take hours on large drives. Run it overnight or when you don't need your PC.

Step 6: Run System File Checker (SFC) and DISM

Corrupt system files can cause instability.

How to repair system files:

Open Command Prompt as Administrator
Run: sfc /scannow
Wait for completion
If issues are found, run: DISM /Online /Cleanup-Image /RestoreHealth
Wait for it to complete (10–15 minutes)
Run sfc /scannow again

Step 7: Update or Roll Back Drivers

Outdated or buggy drivers are the #1 cause of BSOD.

Update drivers:

Open Device Manager
Expand categories (especially Display Adapters, Network Adapters, and System Devices)
Right-click → Update Driver → Search automatically

Roll back drivers:

Right-click → Properties → Driver tab
Click Roll Back Driver (if available)
This reverts to the previous version

For NVIDIA users: Use NVIDIA Clean Installation when installing new drivers.

For AMD users: Use AMD Cleanup Utility before installing new drivers.

Step 8: Check System Temperatures

Overheating can cause random BSOD.

How to check temperatures:

Download HWMonitor or Open Hardware Monitor
Check CPU and GPU temperatures while idle and under load

Rough temperature examples (varies by CPU/GPU model):

Condition	Typical Range
Idle	30–50°C (depends on cooling and ambient temperature)
Under load	60–85°C (may be higher for some high‑performance chips)

Note: These are rough examples. Actual temperatures depend on your specific hardware, cooling solution, and room temperature. Check your component manufacturer's specifications for safe operating ranges.

If temperatures are high:

Clean dust from fans and vents
Ensure proper airflow
Consider reapplying thermal paste (advanced)

Step 9: Disable Overclocking

Overclocking — especially CPU or RAM — can cause instability.

How to disable overclocking:

Enter your BIOS/UEFI (press F2, Del, Esc, or F12 during boot)
Look for overclocking settings (usually under Performance or AI Tweaker)
Reset to default or auto
Save changes and exit

Step 10: Check Windows Update History

Sometimes Windows updates cause BSOD.

How to check:

Open Settings → Windows Update → Update history
Look for recent updates (especially drivers)
If a specific update is the cause, uninstall it

How to uninstall an update:

Go to Settings → Windows Update → Update history
Click Uninstall updates
Select the problematic update
Click Uninstall

Step 11: Use BlueScreenView (Advanced)

For advanced users, BlueScreenView analyzes crash dump files to identify the exact cause.

How to use it:

Download BlueScreenView from NirSoft
Run it as administrator
It will show a list of all BSODs with:
- Error code
- Driver that caused the crash (highlighted in red)
- Date and time
Use this information to target the specific driver or file

Pro tip: The highlighted driver is an important clue, but it isn't always the root cause. Use it as a starting point for further investigation.

Step 12: System Restore or Reset

If nothing works, you can:

System Restore:

Boot into WinRE (Automatic Repair)
Go to Troubleshoot → Advanced options → System Restore
Select a restore point from before the BSOD started

Reset Windows 11:

Go to Settings → System → Recovery → Reset PC
Choose Keep my files (to keep personal files)
Follow the prompts

Common BSOD Error Codes and What They Mean

Error Code	What It Means	Likely Fix
`CRITICAL_PROCESS_DIED`	A critical system process crashed	Update drivers, run SFC, check disk
`IRQL_NOT_LESS_OR_EQUAL`	Driver or software tried to access memory incorrectly	Update drivers, remove recent software
`PAGE_FAULT_IN_NONPAGED_AREA`	Memory access error	Test RAM, update drivers
`SYSTEM_THREAD_EXCEPTION_NOT_HANDLED`	Driver or system file error	Update drivers, roll back recent updates
`VIDEO_TDR_FAILURE`	Graphics driver timeout	Update GPU drivers, reduce overclock
`MEMORY_MANAGEMENT`	Memory management error	Test RAM, update drivers
`DRIVER_OVERRAN_STACK_BUFFER`	Driver buffer overflow	Update drivers, remove recent software
`SYSTEM_SERVICE_EXCEPTION`	System service error	Update drivers, run SFC

How to Analyze BSOD Dump Files

When a BSOD occurs, Windows creates a dump file (.dmp) that contains crash data.

Tools to analyze dump files:

BlueScreenView (free, simple) — shows driver responsible
WhoCrashed (free, user-friendly) — provides plain English analysis
WinDbg (advanced, from Microsoft) — detailed debugging

How to find dump files:

Default location: C:\Windows\Minidump
Or: C:\Windows\MEMORY.DMP

How to Prevent BSOD in the Future

1. Keep Drivers Updated

Update graphics, network, and chipset drivers regularly
Use manufacturer's tools (NVIDIA, AMD, Intel) for automatic updates

2. Monitor System Temperatures

Keep your PC clean and well-ventilated
Use temperature monitoring tools

3. Test Your Hardware Regularly

Run mdsched.exe for RAM
Run chkdsk for disk health
Use CrystalDiskInfo for SSD health

4. Install Windows Updates

Install updates regularly
But wait a few days before installing major updates (to catch issues)

5. Be Careful with Overclocking

Test stability after overclocking
Use stress-testing tools (Prime95, FurMark)

6. Use Quality Power Supply

Ensure your PSU has enough wattage
Use a surge protector or UPS

What If You Want to Monitor Your System Automatically?

Manually checking for problems is time-consuming.

You have to:

Monitor temperatures
Check for driver issues
Watch for disk errors
Track system instability

That's why I built SysPulse — a lightweight Windows security and performance monitoring tool.

SysPulse:

Tracks CPU, RAM, Disk, and Network usage in real-time

How to Reset Windows 11 Without Losing Your Files (Complete Guide)

Darkssel — Sun, 23 Aug 2026 20:43:46 +0000

Your PC is acting up.

Programs crash randomly.

Files take forever to open.

The system feels sluggish and unstable.

You've tried everything — cleaning up disk space, disabling startup apps, running virus scans.

Nothing works.

You think:

"Do I have to reinstall Windows from scratch?"

That thought comes with another one:

"But what about my files? My photos? My documents?"

Here's the good news:

You can reset Windows 11 without losing your personal files.

And it's easier than you think.

This guide walks you through everything you need to know — from preparation to the reset process itself.

Reset vs Clean Install: What's the Difference?

Before we start, let's clear up a common confusion.

Option	What It Does	What You Lose
Reset (Keep My Files)	Reinstalls Windows, keeps your personal files	Apps and settings
Clean Install	Wipes everything — Windows, apps, files, settings	Everything
Reset (Remove Everything)	Reinstalls Windows, removes all personal files	Everything except Windows itself

This guide covers the first option: Reset (Keep My Files).

It's the safest way to refresh your system without losing your documents, photos, music, and downloads.

Before You Reset: 4 Essential Steps

A little preparation goes a long way.

1. Back Up Your Most Important Files

Even though the reset process keeps your files, it's always wise to have a backup.

Copy important documents, photos, and videos to an external drive or cloud storage
Export your browser bookmarks
Save any work-in-progress files

Why? Accidents happen. Power outages happen. A backup ensures you're covered.

2. Note Down Your Installed Apps

The reset will remove all your installed applications.

You'll need to reinstall them afterward.

What to do:

Take a screenshot of your installed apps
Or use a tool like winget list (Command Prompt) to export a list
Make a note of license keys or login credentials

3. Make Sure Your PC Is Plugged In

If you're using a laptop, plug it into a power source.

A reset takes time — and losing power in the middle can cause problems.

4. Connect to the Internet

Windows may need to download files during the reset.

A stable internet connection helps the process go smoothly.

How to Reset Windows 11 (Keep Your Files)

There are two ways to do this — choose the one that works for your situation.

Method 1: Reset From Settings (If Your PC Boots Normally)

This is the easiest method. Use it if your PC is still working but slow or unstable.

Step 1: Open Settings

Press Win + I to open Settings
Or click the Start menu → Settings (gear icon)

Step 2: Go to Recovery

Click System in the left sidebar
Scroll down and click Recovery

Step 3: Start the Reset

Under Recovery options, find Reset this PC
Click the Reset PC button

Step 4: Choose "Keep My Files"

You'll see two options:
- Keep my files — keeps personal files, removes apps and settings
- Remove everything — removes everything
Select Keep my files

Step 5: Cloud Download or Local Reinstall

Windows will ask how you want to reinstall:
- Cloud download — downloads fresh Windows files (requires internet)
- Local reinstall — uses Windows files already on your PC
Choose Cloud download for the freshest version

Step 6: Review Settings and Reset

Windows will show what will be removed
Click Next, then Reset
The process may take 20–60 minutes

Your PC will restart several times. Don't interrupt the process.

Method 2: Reset From WinRE (If Your PC Won't Boot)

If your PC doesn't start normally, you can reset from the Windows Recovery Environment (WinRE).

Step 1: Enter WinRE

Turn on your PC
As soon as the manufacturer logo appears, hold the power button to force shutdown
Repeat this 2–3 times until you see "Preparing Automatic Repair"
Then click Advanced options

Step 2: Go to Reset Options

Click Troubleshoot → Reset this PC

Step 3: Choose "Keep My Files"

Select Keep my files

Step 4: Choose Installation Method

Select Cloud download or Local reinstall
Cloud download is recommended

Step 5: Follow the Prompts and Reset

Review the settings
Click Reset
Wait for the process to complete

What Happens After the Reset?

Once the reset is complete:

Windows will boot normally — like a fresh installation
Your personal files are still there — check your Documents, Pictures, Music, and Downloads folders
All your apps are gone — you'll need to reinstall them
Windows settings are reset to default — you'll need to reconfigure some preferences

What to Do After the Reset

1. Reinstall Your Apps

Start with the essentials:

Browser (Chrome, Edge, Firefox)
Antivirus (if you use one)
Office suite
Communication apps (Discord, Slack, Zoom)
Cloud sync apps (OneDrive, Google Drive)
Games and game launchers

2. Update Windows

Go to Settings → Windows Update
Check for and install all available updates

3. Update Drivers

Open Device Manager (right-click Start → Device Manager)
Check for outdated drivers — especially graphics and network drivers

4. Restore Your Backup

Copy your backed-up files back to their original locations
Restore browser bookmarks

5. Monitor Your System

After a reset, your PC is clean and fresh.

This is the perfect time to keep it that way.

What If You Want to Monitor Your System Automatically?

A fresh reset is a great opportunity to start clean.

But as you install new apps and use your PC, things can slow down again — without you noticing.

That's why I built SysPulse — a lightweight Windows security and performance monitoring tool.

SysPulse:

Tracks CPU, RAM, Disk, and Network usage in real-time
Alerts you when processes spike or crash
Logs startup changes and system events
Uses less than 30MB of RAM — less than a single browser tab
Sends Telegram notifications when unusual activity is detected

You can set it up once and let it watch your PC for you.

You can find it at: syspulse.pro

Summary Table

Step	Action
1	Back up your important files
2	Note down your installed apps
3	Plug in your PC (if laptop)
4	Connect to the internet
5	Go to Settings → System → Recovery → Reset PC
6	Select "Keep My Files"
7	Choose Cloud Download
8	Click Reset and wait
9	Reinstall apps and update drivers

Final Thought

A reset is like a spa day for your PC.

It gives Windows a fresh start — without the stress of losing your files.

If your PC is slow, buggy, or unstable, this is the safest way to bring it back to life.

Start with the preparation steps, follow the guide, and you'll have a faster, cleaner system in less than an hour.

Windows 11 KB5077181 Causing Boot Loops? Here's How to Fix It

Darkssel — Sun, 23 Aug 2026 18:00:55 +0000

You turn on your PC.

The manufacturer logo appears.

Then the spinning circle of dots appears.

And appears.

Your PC keeps restarting — over and over — and never reaches the desktop.

You might think:

"Did my PC just die? Did I get hacked?"

Maybe not.

In early 2026, some Windows 11 users reported boot loops and black screens after installing a specific update — KB5077181.

While Microsoft hasn't officially confirmed widespread issues with this update, many users have shared their experiences in forums and Microsoft Q&A.

If you're stuck — or helping someone who is — this guide will help you recover.

What Is KB5077181?

KB5077181 was a cumulative update released on February 10, 2026.

It included security fixes, quality improvements, and new Secure Boot certificates.

For most users, it installed without problems.

But for some, it caused:

Boot loops (infinite restarts)
Black screens
Failed sign-ins with SENS errors
DHCP and Wi-Fi issues
Installation errors like 0x800f0983 and 0x800f0991

How to Know If You're Affected by KB5077181

If you're stuck in a boot loop after installing updates, here's how to check:

Enter the Windows Recovery Environment (WinRE):
- Restart your PC
- As soon as the manufacturer logo appears, hold the power button to force shutdown
- Repeat this 2–3 times until you see "Preparing Automatic Repair"
- Then click Advanced options
Check installed updates:
- Go to Troubleshoot → Advanced options → Uninstall Updates
- Look for KB5077181 in the list of recently installed updates

If you see KB5077181, it may be the cause of your problem.

Fix 1: Uninstall KB5077181 Using DISM (Recommended)

Because KB5077181 is a combined package (LCU + SSU), Microsoft's preferred method for removal is using DISM.

Important: In WinRE, the Windows drive isn't always C:. It could be D:, E:, or another letter.

How to find the correct drive:

Enter WinRE → Command Prompt
Run:

diskpart
list volume

Look for the volume that contains your Windows installation. You can identify it by checking for the Windows, Program Files, and Users folders.

Example:

dir C:\
dir D:\

Look for Windows, Program Files, and Users folders — that's your Windows drive

Once you've found the correct drive (let's say it's D:):

List all installed packages:

dism /image:D:\ /get-packages

Find the package name for KB5077181 (it will look like Package_for_KB5077181~...)
Copy the full package name
Remove it with:

dism /image:D:\ /remove-package /packagename:Package_for_KB5077181~...

Restart your PC

Fix 2: Uninstall Using WinRE Interface (Alternative)

If you prefer a graphical method:

Enter WinRE
Go to Troubleshoot → Advanced options → Uninstall Updates
Select Uninstall latest quality update
Follow the on-screen instructions
Restart your PC

Fix 3: Uninstall Using wusa.exe (Alternative, May Not Work)

Some users have reported success with this method.

However, Microsoft notes that wusa /uninstall may not work for combined LCU+SSU packages.

If you want to try it:

Enter WinRE → Command Prompt
Run:

wusa /uninstall /kb:5077181 /quiet /norestart

Restart your PC

If this doesn't work, use the DISM method above.

Fix 4: Reset Secure Boot Keys (If Applicable)

In some cases, users reported that Secure Boot keys were cleared or corrupted after installing KB5077181.

Important: This is not a universal issue. It appears to affect specific hardware configurations.

If you're affected:

Enter your BIOS/UEFI (usually by pressing F2, Del, Esc, or F12 during boot)
Look for Secure Boot settings (usually under Security or Boot)
Find and use Reset/Install default keys or Factory Key Provision — not just "Clear"
Save changes and exit

Alternative: Updating your BIOS to the latest version may also help.

Fix 5: System Restore (If Available)

If you had System Restore enabled:

Enter WinRE
Go to Troubleshoot → Advanced options → System Restore
Select a restore point from before the update
Follow the on-screen instructions

Fix 6: Clean Install (Last Resort)

If nothing else works:

Create a Windows 11 installation USB
Boot from the USB
Select Custom installation
Delete all partitions on the system drive
Click Next to install

Warning: This erases all data on your system drive.

Prevention: How to Avoid This in the Future

Delay updates — wait a few days before installing new updates
Create restore points — before each major update
Pause updates — if you're unsure, pause updates for a week

What If You Want to Monitor Your System Automatically?

Manually checking for problems after every update is tedious.

That's why I built SysPulse — a lightweight Windows security and performance monitoring tool.

SysPulse:

Tracks CPU, RAM, Disk, and Network usage in real-time
Alerts you when processes spike or crash
Logs startup changes and system events
Uses less than 30MB of RAM
Sends Telegram notifications when unusual activity is detected

You can set it up once and let it watch your PC for you.

You can find it at: syspulse.pro

Summary Table

Problem	Solution
Boot loop after KB5077181	Uninstall using DISM (recommended) or WinRE
Secure Boot keys corrupted	Reset to factory defaults in BIOS
DISM doesn't work	Try wusa.exe (may not work for combined packages)
No restore point	Try Safe Mode or clean install

Final Thought

KB5077181 was a frustrating experience for some Windows 11 users.

If you're stuck in a boot loop, don't panic.

Start with the recommended fix:

Enter WinRE
Uninstall using DISM

If that doesn't work, try the other methods in order.

Many users may be able to recover their systems without reinstalling Windows.

Why Is Windows 11 So Slow? 7 Reasons and How to Fix It

Darkssel — Sun, 23 Aug 2026 11:58:02 +0000

You upgraded to Windows 11 because it looked fresh, modern, and promised better performance.

But now?

File Explorer takes 5 seconds to open.

Right-clicking anywhere lags for 2 seconds.

Apps freeze for no reason.

Your RAM is constantly at 80% usage — even when you're "doing nothing."

You might think:

"Is my PC too old for Windows 11?"

Or worse:

"Is this just how Windows 11 is?"

No. Windows 11 is not supposed to be this slow.

And your PC is probably not the problem.

Many users have reported performance issues with Windows 11 — especially after recent updates. Microsoft has acknowledged some of these problems, particularly with File Explorer.

This guide covers 7 reasons why Windows 11 feels slow — and practical fixes for each one.

No reinstalling. No buying new hardware. Just actionable steps.

Let's go.

1. File Explorer Is Painfully Slow

File Explorer is one of the most common sources of performance complaints in Windows 11.

You open File Explorer — and wait.

You right-click — and wait.

You navigate to a folder — and wait.

Why this happens:

Windows 11's File Explorer is heavily integrated with:

OneDrive — constantly syncing and checking file status
Quick Access — loading recent files and frequent folders
Search indexing — preparing search results
Cloud providers — Dropbox, Google Drive, iCloud

These integrations can add extra work when you open or navigate through File Explorer, especially when cloud storage and recent-file features are active.

How to fix it:

Open File Explorer
Click the View menu (top bar) → Options → Change folder and search options
Under the General tab, change Open File Explorer to: from "Home" to "This PC"
Uncheck:
- Show recently used files in Quick Access
- Show frequently used folders in Quick Access
- Show files from Office.com
Click Apply → OK

What to expect: This reduces the loading time significantly because File Explorer no longer queries OneDrive, recent files, or cloud statuses. Many users report much faster performance after this change.

2. Visual Effects and Animations Are Slowing You Down

Windows 11 looks beautiful — but those animations, transparency effects, and shadows cost performance.

On older or mid-range PCs, these effects can make everything feel laggy.

How to fix it:

Press Win + R, type sysdm.cpl, press Enter
Go to the Advanced tab
Under Performance, click Settings
Select Adjust for best performance (disables everything)
- Or select Custom and keep only:
  - Smooth edges of screen fonts
  - Show thumbnails instead of icons

What you lose: Animations, shadows, and transparency.

What you gain: A snappier, more responsive PC.

Pro tip: You can also turn off Transparency effects in Settings → Personalization → Colors → Transparency effects → Off.

3. Memory Compression: When It Helps and When It Doesn't

Open Task Manager → Performance → Memory.

You might see:

"Memory Compression" using 200–500MB

This is a normal Windows feature that compresses RAM to fit more data. It's generally helpful, especially on systems with 8GB or less RAM.

However, on systems with 16GB+ RAM, Memory Compression can sometimes consume unnecessary CPU resources without providing significant benefit.

How to check if it's affecting you:

Open Task Manager → Performance → Memory
Check the "Memory Compression" value
Also monitor your CPU usage

Optional tweak (for 16GB+ systems only):

Open PowerShell as Administrator
Run: Get-MMAgent
Look for MemoryCompression — if it says True, it's enabled
To disable it: Disable-MMAgent -MemoryCompression
Restart your PC

Important: This is an optional tweak. Most users should leave Memory Compression enabled. Only consider disabling it if you have 16GB+ RAM and notice high CPU usage from memory management.

4. Background Services and Bloatware

Windows 11 comes with many services running by default.

Some are useful. Many are not.

Common resource-hungry services include:

SysMain (SuperFetch) — preloads apps for faster startup
Windows Search — indexes files (can use CPU/disk)
Print Spooler — if you don't have a printer
Connected User Experiences and Telemetry — sends usage data to Microsoft
Xbox services — game features (if you don't game)

How to fix it:

Press Win + R, type services.msc, press Enter
Right-click any service → Properties
Change Startup type to Disabled (or Manual)
Click Apply → OK

Safe to disable (if you don't use them):

Service	When to disable
Print Spooler	No printer
Xbox services	Don't game
Windows Search	Use third-party search or rarely search
SysMain	On SSD, the benefit is minimal

Be careful: Only disable services you understand. If unsure, research first.

5. Startup Programs Overload

This is the #1 reason PCs get slower over time.

Every app you install wants to start with Windows.

After a year, you have 20+ apps launching at boot.

Each one adds seconds to your boot time and consumes RAM and CPU.

How to fix it:

Press Ctrl + Shift + Esc to open Task Manager
Click the Startup tab
Sort by Startup Impact (High to Low)
Right-click and Disable everything you don't need immediately

Common offenders:

Spotify
Discord
Adobe Creative Cloud
Steam / Epic Games Launcher
Zoom / Teams

Pro tip: You can still open these apps manually. They just won't slow down your boot.

6. OneDrive and Cloud Sync Overload

OneDrive is deeply integrated into Windows 11.

It constantly syncs files, checks for changes, and keeps your cloud storage updated.

On slower internet connections — or with large folders — OneDrive can consume significant CPU, memory, and disk I/O.

How to check:

Open Task Manager → Processes tab
Look for OneDrive — check its CPU/Memory/Disk usage

How to fix it:

Open OneDrive Settings (right-click OneDrive icon in system tray → Settings)
Under the Account tab → Choose folders — choose only essential folders to sync
Under the Sync and backup tab → pause syncing during work hours

Alternative: If you don't use OneDrive, uninstall it entirely — Settings → Apps → OneDrive → Uninstall.

7. Microsoft Copilot and AI Features

Windows 11 has been gradually adding AI features:

Copilot (sidebar assistant)
Recall (screenshots your screen periodically) — available in some regions
AI-powered search
AI-powered suggestions in File Explorer

These features can consume system resources — and many users prefer to disable them.

How to disable Copilot:

Right-click the taskbar → Taskbar settings
Toggle Copilot off

How to disable other AI features:

Open Settings → Privacy & security
Look for Recall & snapshots (if present) — disable it
Under Search permissions → turn off Search suggestions

For advanced users (Windows Pro):

Press Win + R, type gpedit.msc
Go to User Configuration → Administrative Templates → Windows Components → Windows Copilot
Set Turn off Windows Copilot to Enabled

What to expect: Disabling these features can improve performance on some systems, but the impact varies depending on your hardware and usage patterns.

Summary Table

Problem	Quick Fix
File Explorer lag	Change Open File Explorer to "This PC", disable recent files
Visual effects slow	Disable animations (Performance Options)
Memory Compression	Optional tweak — only disable on 16GB+ systems if CPU usage is high
Background services	Disable non-essential services (Print Spooler, Xbox, etc.)
Startup overload	Disable unnecessary startup apps
OneDrive slowness	Limit sync folders or pause sync
Copilot/AI features	Disable Copilot and AI search suggestions

What If You Want to Monitor Performance Automatically?

Manually checking all of the above takes time.

You have to:

Check Task Manager regularly
Monitor CPU, RAM, and Disk usage
Watch for new startup items
Track background services

Instead of doing all that manually, I built SysPulse — a lightweight Windows security and performance monitoring tool.

SysPulse:

Tracks CPU, RAM, Disk, and Network usage in real-time
Alerts you when processes spike or crash
Logs startup changes and background services
Uses less than 30MB of RAM — less than a single browser tab
Sends Telegram notifications when unusual activity is detected

You can set it up once and let it watch your PC for you.

You can find it at: syspulse.pro

Final Thought

Windows 11 doesn't have to be slow.

Many performance issues come from:

File Explorer settings
Visual effects
Startup overload
Background services

Start with the easiest fixes:

Change File Explorer to open "This PC"
Disable visual effects
Turn off unnecessary startup apps

If you want to go further, disable background services, OneDrive syncing, and AI features.

The result: A faster, more responsive Windows 11 — without buying new hardware.

How to Speed Up Windows 10/11 (Complete Guide)

Darkssel — Sat, 22 Aug 2026 20:37:59 +0000

Your PC was fast when you first bought it.

Now it feels like it's running through mud.

Programs take forever to open.

The fan spins up for no reason.

Even moving between folders feels sluggish.

You might think:

"Is my PC too old? Do I need to buy a new one?"

Probably not.

Most Windows slowdowns are caused by misconfigurations, clutter, and unnecessary background activity — not hardware age.

This guide combines everything you need to speed up Windows — from the quick wins to the advanced tweaks.

No reinstalling Windows. No buying new hardware. Just practical fixes.

Let's go.

1. Disable Unnecessary Startup Programs

This is the #1 reason PCs get slower over time.

Every app you install wants to start with Windows.

After a year, you have 20+ apps launching at boot.

Each one adds seconds to your boot time and consumes RAM and CPU.

How to fix it:

Press Ctrl + Shift + Esc to open Task Manager
Click the Startup tab
Sort by Startup Impact (High to Low)
Right-click and Disable everything you don't need immediately

What to keep:

Antivirus (if you use one)
Graphics drivers (NVIDIA, AMD, Intel)
Cloud sync only if you need it constantly

What to disable:

Spotify, Adobe, Discord, Steam, Epic Games Launcher, etc.

Pro tip: You can still open these apps manually. They just won't slow down your boot.

2. Turn Off Visual Effects

Windows looks nice — but those animations cost performance.

On older or budget PCs, disabling visual effects can make everything feel snappier.

How to do it:

Press Win + R, type sysdm.cpl, press Enter
Go to the Advanced tab
Under Performance, click Settings
Select Adjust for best performance (disables everything) or Custom (choose what to keep)

What to keep (optional):

Smooth edges of screen fonts
Show thumbnails instead of icons

What to disable (safe to turn off):

Animations
Transparency effects
Shadows
Fades and sliding menus

The difference: Your PC will feel more responsive immediately.

3. Free Up Disk Space

When your system drive (usually C:) is nearly full, Windows slows down.

It needs space for:

Virtual memory (pagefile)
Temporary files
System restore points
Caching

How to clean up:

Open This PC → right-click C: → Properties → Disk Cleanup
Click Clean up system files
Select everything you can remove:
- Windows Update Cleanup (often GBs)
- Temporary files
- Recycle Bin
- Previous Windows installations

Additional steps:

Uninstall programs you don't use (Settings → Apps)
Move large files (videos, game installs) to an external drive
Use Storage Sense (Settings → System → Storage → turn it on)

Target: Keep at least 15–20% free space on your system drive.

4. Disable Background Apps

Many apps run in the background even when you're not using them.

They consume CPU, RAM, and sometimes even network bandwidth.

How to disable them:

Windows 10: Settings → Privacy → Background apps → Turn off "Let apps run in the background" or disable individual apps
Windows 11: Settings → Apps → Installed apps → click each app → Advanced options → Background apps permissions → Never

Also check:

Task Manager → Processes — look for apps you don't recognize
System Tray (bottom-right) — right-click and quit any unnecessary tools

5. Change Power Plan to High Performance

Windows has different power plans.

On laptops, the default is often Balanced or Power Saver to save battery.

But on desktops — or when plugged in — High Performance gives you full CPU speed.

How to change it:

Search "Power Options" in the Start menu
Select High Performance
If you don't see it, click Show additional plans (on Windows 11) or Create a power plan → High Performance

For gaming PCs: Look for Ultimate Performance (available on some Windows editions).

Battery warning: This uses more power on laptops. Use it only when plugged in.

6. Update Drivers

Outdated drivers can cause performance issues — especially graphics, network, and chipset drivers.

How to check and update:

Open Device Manager (right-click Start → Device Manager)
Expand categories (especially Display Adapters, Network Adapters, and System Devices)
Right-click → Update Driver → Search automatically

Alternative: Visit your motherboard or laptop manufacturer's website and download the latest drivers.

Pro tip: Use Intel Driver & Support Assistant or Dell Update / Lenovo Vantage for automatic driver updates.

7. Consider Disabling Windows Search Indexing (Optional)

Windows Search indexes your files so you can find them quickly.

But indexing uses CPU and disk I/O — and if you don't search often, it may not be worth the resource cost.

How to disable indexing (optional):

Press Win + R, type services.msc, press Enter
Find Windows Search
Right-click → Properties
Change Startup type to Disabled
Click Stop → Apply → OK

Important note: This is an optional tweak. On modern SSDs, Windows Search has minimal performance impact. Only disable it if you actively notice high disk or CPU usage from the search indexer and don't rely on instant file search.

What you lose: Instant search results. You can still find files — it just takes a moment longer.

8. Run Disk Cleanup and Optimization

Your drive can become fragmented over time (HDD) or need TRIM (SSD).

How to do it:

Open This PC → right-click C: → Properties → Tools
Under Optimize and defragment drive, click Optimize
Select your drive → click Optimize

For HDD: This defragments files (can take hours — run overnight).

For SSD: This runs TRIM (takes seconds).

9. Disable Startup Services You Don't Need

Some services launch at boot and run constantly — using CPU and RAM.

How to check:

Press Win + R, type msconfig, press Enter
Go to the Services tab
Check Hide all Microsoft services (critical — don't disable these)
Look at the remaining services

What to disable (usually safe):

Print Spooler (if you don't use a printer)
Fax service
XBox services (if you don't game)
Bluetooth services (if you don't use Bluetooth)
Windows Error Reporting (you can disable)

Be careful: Research a service before disabling it if you're unsure.

10. Malware and Antivirus Conflicts

This is a paradox: security software can slow down your system.

Third-party antivirus tools often:

Scan every file you open
Inject into every process
Slow down file transfers

What to do:

Run a full scan with Windows Security (built-in) or Malwarebytes
If no threats are found, temporarily uninstall third-party antivirus
Check if performance improves

For many users, Windows Defender provides sufficient built-in protection without requiring another antivirus.

11. Check for System File Corruption

Corrupted system files can cause slowdowns, crashes, and instability.

How to check and repair:

Open Command Prompt as Administrator
Run: sfc /scannow
Wait for the scan to complete

If sfc finds issues but can't fix them:

Run: DISM /Online /Cleanup-Image /RestoreHealth
Wait for it to complete (10–15 minutes)
Run sfc /scannow again

Pro tip: Run this once a month to keep your system healthy.

Summary Table

Issue	Quick Fix
Slow boot	Disable startup apps
Slow performance	Disable visual effects
Full drive	Run Disk Cleanup
Background apps	Disable in Settings
Laptop slow unplugged	Change power plan to High Performance
Outdated drivers	Update via Device Manager
Search indexing	Disable only if causing high usage (optional)
Services consuming resources	Disable unnecessary services in msconfig
Antivirus slowing system	Use Windows Defender only
System file issues	Run `sfc /scannow` and `DISM`

What If You Want to Monitor Performance Automatically?

Manually checking all of the above takes time.

You have to:

Check Task Manager regularly
Monitor CPU and RAM usage
Watch for new startup items
Track background services

Instead of doing all that manually, I built SysPulse — a lightweight Windows security and performance monitoring tool.

SysPulse:

Tracks CPU, RAM, Disk, and Network usage in real-time
Alerts you when processes spike or crash
Logs startup changes and background services
Uses less than 30MB of RAM — less than a single browser tab
Sends Telegram notifications when unusual activity is detected

You can set it up once and let it watch your PC for you.

You can find it at: syspulse.pro

Final Thought

You don't need to buy a new PC.

Most Windows slowness comes from:

Too many startup programs
Cluttered disk
Visual effects
Background apps

Start with the simple fixes:

Disable startup apps
Turn off visual effects
Run Disk Cleanup
Change power plan

If you want to go further, disable background apps, update drivers, and check for system file corruption.

The result: A faster, more responsive PC — without spending a dollar.

Why Is My Windows CPU Usage at 100% for No Reason?

Darkssel — Sat, 22 Aug 2026 20:31:10 +0000

You're doing nothing.

No games. No videos. No heavy apps.

Just the desktop.

And yet — your fan is screaming.

You open Task Manager.

CPU: 100%

You freeze.

You might think:

"Is my PC broken? Do I have a virus? What is going on?"

You're not alone.

This is one of the most Googled Windows problems — and one of the most frustrating.

The good news?

CPU usage at 100% is rarely a mystery.

There's always a cause. You just need to know where to look.

This guide covers 7 common reasons why your CPU spikes to 100% — and exactly how to fix each one.

1. Check Task Manager First (But Do It Right)

You probably already opened Task Manager.

But did you look at the right place?

How to check properly:

Press Ctrl + Shift + Esc
Go to the Processes tab
Click the CPU column to sort from highest to lowest

Now ask yourself:

What process is at the top?

Common culprits include:

Antimalware Service Executable — Windows Defender scanning
System or System Interrupts — hardware/driver issues
Service Host: Local System — Windows services
Your browser — especially with many tabs or extensions
A game launcher downloading updates in the background
A cloud sync tool — OneDrive, Google Drive, Dropbox

Quick fix: If you see a non-essential app at the top, right-click and select End Task. Watch if CPU drops immediately.

2. The Hidden Culprit: "System Interrupts"

This one confuses almost everyone.

You open Task Manager and see:

System Interrupts — 30–50% CPU

You think: "What is that? Is it malware?"

No. It's not a process. It's a placeholder for hardware interrupts.

It means something connected to your PC is constantly asking for attention.

Common causes:

Faulty or outdated drivers (especially network, audio, or chipset)
USB devices malfunctioning
Internal hardware conflicts
A failing hard drive or SSD

What to do:

Unplug all USB devices except mouse and keyboard — see if CPU drops
Update your drivers — especially chipset, network, and audio drivers
Disable devices one by one in Device Manager to find the culprit
Check disk health with chkdsk /f /r C: — failing drives can cause this

If "System Interrupts" is constantly high, it's almost always a driver or hardware issue.

3. Windows Defender (Antimalware Service Executable)

MsMpEng.exe — also known as Antimalware Service Executable — is Windows Defender.

It's a good thing. It protects you.

But sometimes it decides to scan everything at once.

This can push your CPU to 100% for 5–15 minutes.

Why this happens:

A scheduled scan is running
You just downloaded a large file
You opened a folder with many files
Windows is doing a full system scan

What to do:

Wait — it usually finishes within 10–20 minutes
Check your scan schedule — open Windows Security → Virus & threat protection → Scan options → change scan frequency
Exclude large folders — if you know specific folders are safe (like your games or development folders), add them to exclusions

Pro tip: You can run a quick scan manually and schedule full scans for off-hours.

4. Background Windows Updates

Windows Update loves to run when you least expect it.

And it can consume significant CPU resources — especially when installing or downloading multiple updates.

How to check:

Open Settings → Windows Update
Look for "Downloading" or "Installing" status

What to do:

Let it finish — updates are important
Change your Active Hours in Windows Update settings so updates don't run during your work hours
If it's stuck, restart your PC and check again

5. Browser Tabs and Extensions

Modern browsers are like operating systems.

Each tab, each extension, each background process consumes CPU.

Even when you're "not doing anything," your browser might be:

Refreshing background tabs
Running ad trackers
Loading news feeds
Scanning for updates

What to do:

Open Task Manager → Processes tab
Look at your browser's CPU usage
If it's high, check your browser's built-in task manager:
- Chrome: Shift + Esc
- Edge: Shift + Esc
- Firefox: about:performance

Quick fix: Close unused tabs. Disable or remove unnecessary extensions. Restart your browser.

6. Hidden Background Services

Windows runs dozens of services in the background.

Some of them are hungry.

Common CPU-hungry services include:

SysMain — SuperFetch (preloads apps for faster startup)
Windows Search — indexes files for faster search
WMI Provider Host — system monitoring
Print Spooler — if you have printers connected

How to check and disable:

Open Task Manager → Services tab
Click Open Services at the bottom
Find the service → right-click → Properties
Change Startup type to Manual or Disabled

Be careful: Only disable services you understand. If unsure, research first.

7. Malware and Crypto Miners

This is what everyone fears.

Crypto mining malware can push your CPU to 100% constantly.

Signs of crypto malware:

CPU at 100% even when idle
Fan is always loud
PC feels slow and unresponsive
No known process shows high CPU usage

What to do:

Run a Full Scan with Windows Security
Run a second scan with Malwarebytes (free)
Use Process Explorer from Sysinternals to see hidden processes
Check Startup and Scheduled Tasks for unknown items

If you find nothing but still suspect malware: Boot into Safe Mode and run scans again.

Summary Table

Symptom	Likely Cause	Quick Fix
CPU high for a few minutes	Windows Update or Defender scan	Wait or schedule off-hours
"System Interrupts" high	Driver or hardware issue	Update drivers, unplug USB devices
Browser at top of CPU list	Tabs/extensions	Close tabs, remove extensions
Unknown process at top	Hidden app/service	End Task, research, or disable
CPU high all the time	Malware or crypto miner	Run full scans, check startup
CPU spikes when idle	Background tasks	Check Task Scheduler

What If You Want to Monitor CPU Usage Automatically?

Checking Task Manager manually is useful.

But it only shows you what's happening right now.

What if CPU spikes to 100% while you're away?

When you come back, Task Manager shows 10% again — and you never know what happened.

That's why I built SysPulse — a lightweight Windows security monitoring tool.

SysPulse:

Tracks CPU, RAM, Disk, and Network usage in real-time
Alerts you when CPU spikes unexpectedly
Logs processes that consume high resources
Uses less than 30MB of RAM — less than a single browser tab
Sends notifications when suspicious processes appear

You don't have to stare at Task Manager all day.

SysPulse watches your PC for you.

You can find it at: syspulse.pro

Final Thought

100% CPU usage is frustrating — but it's almost always fixable.

Start with the simplest checks:

Task Manager → sort by CPU
Check for Windows Defender scans
Look for "System Interrupts"
Close browser tabs and extensions

Most of the time, the problem is a temporary task that will finish on its own.

If CPU stays high constantly, it's time for deeper investigation — driver updates, malware scans, or hardware checks.

The important thing: Don't panic. Investigate methodically.

Why Did Windows Create This Folder? How to Find Out What Created Unknown Files

Darkssel — Sat, 22 Aug 2026 12:11:10 +0000

Have you ever opened a folder on your Windows PC and suddenly noticed a file or folder you don't remember creating?

Maybe it has a strange name.

Maybe it appeared after restarting your computer.

Or perhaps you found a new folder on your desktop, Downloads folder, AppData directory, or somewhere else on your drive and wondered:

"Why is this here?"

Finding an unfamiliar file doesn't automatically mean your computer has been hacked. Windows, installed applications, installers, updates, browsers, and background services can create files and folders without asking you directly.

The important question is:

How can you determine what created it?

Here are several practical ways to investigate.

1. Check When the File or Folder Was Created

The first thing to check is the creation time.

Right-click the file or folder and select:

Properties

Look at:

Created
Modified
Accessed

The creation time can give you an important clue.

For example, if you discover a strange folder at 10:30 PM and Windows says it was created at 10:28 PM, think about what happened around that time.

Did you:

Install an application?
Run an update?
Start a game?
Open your browser?
Connect a USB device?
Restart Windows?
Run a script?

Timing can help connect the file to an event.

However, timestamps aren't perfect evidence by themselves. Some applications copy, move, extract, or recreate files, which can make the timestamps less straightforward than they appear.

2. Think About Where the File Was Created

The location of the file is often just as important as its name.

For example, seeing a folder inside:

C:\Program Files

is very different from finding an unknown executable in:

C:\Users\YourName\AppData\Roaming

Some Windows and application directories normally contain files that users never manually create.

Common locations worth understanding include:

Program Files
ProgramData
AppData\Local
AppData\Roaming
Downloads
Temp
Desktop
Startup folders

Don't delete something simply because the location looks unfamiliar.

First determine what application or Windows component owns it.

3. Look at the File Extension

The file extension can provide another clue.

For example:

.exe

usually indicates an executable program.

.dll

is a Windows or application library.

.ps1

is a PowerShell script.

.bat

is a batch file.

.cmd

is a Windows command script.

.tmp

is commonly associated with temporary files.

The extension doesn't tell you whether a file is safe.

A malicious program can use a normal-looking extension, while legitimate software can create files that look suspicious to an inexperienced user.

Think of the extension as a clue, not a verdict.

4. Check the Digital Signature

If the unknown file is an executable, checking its digital signature can be useful.

Right-click the file and select:

Properties → Digital Signatures

If a valid signature exists, you may be able to identify the publisher.

For example, a file associated with a known software vendor is generally easier to explain than an unsigned executable with a random filename.

But again, a valid signature doesn't automatically guarantee that a file is safe, and the absence of a signature doesn't automatically mean malware.

Use it as one piece of evidence.

5. Check What Program Is Running It

If you find an unfamiliar executable, Task Manager can help.

Open:

Task Manager → Details

Look for the process associated with the file.

You can right-click a process and choose:

Open file location

This lets you see where the running executable actually exists.

This is useful because the filename alone can be misleading.

For example, two different programs could use similar names, while their actual file paths are completely different.

The full path often gives you much more information.

6. Check Task Scheduler

Task Scheduler is another important place to investigate.

Windows and installed applications can create scheduled tasks that automatically launch programs or scripts.

Open:

Task Scheduler

Then inspect:

Task Scheduler Library

Pay attention to tasks that:

Run at startup
Run periodically
Run after logon
Launch unfamiliar programs
Execute scripts
Run from unusual directories

If an unknown folder appears at exactly the same time a scheduled task runs, you've found an important lead.

Don't immediately delete the task.

First determine what software created it and whether it has a legitimate purpose.

7. Check Startup Programs

Some applications create files during startup.

Open:

Task Manager → Startup apps

Look for applications you don't recognize.

If you notice an unfamiliar startup application and also discover files being created around the same time Windows starts, investigate the two together.

The relationship between events is often more useful than looking at a single file in isolation.

8. Check Event Viewer

Windows Event Viewer can provide additional information when you're trying to understand what happened around a specific time.

Press:

Win + R

and enter:

eventvwr.msc

Depending on what you're investigating, check relevant Windows logs around the time the file appeared.

Event Viewer can be overwhelming because Windows records a large amount of information.

You don't need to inspect everything.

Start with the exact timestamp of the suspicious file creation and look for events around that period.

9. Don't Forget Software Updates

One of the most common explanations for unexpected files is software updating itself.

Applications may create:

Temporary directories
Installer files
Update packages
Logs
Cache files
Configuration files

Windows itself also performs background maintenance and updates.

So if a new folder appeared immediately after installing or updating software, that may be a perfectly normal explanation.

Before assuming something malicious happened, ask:

"What changed on my PC recently?"

That simple question can eliminate many false alarms.

10. What If the File Keeps Coming Back?

This is more interesting.

Suppose you delete an unknown file, but it appears again a few hours later.

That suggests something is recreating it.

Possible causes include:

A running application
A scheduled task
A startup program
An updater
A Windows service
A script
Malware

Instead of repeatedly deleting the file, try to identify what creates it again.

The timing can be extremely useful.

For example:

File disappears → 30 minutes later → file returns

If the same process or scheduled task runs at that time, you may have found the source.

What If the File Looks Suspicious?

Be more careful if several unusual things happen together.

For example:

An unknown executable appears
The file is located in an unusual directory
It runs automatically
It creates additional files
CPU usage suddenly increases
Network activity appears
A strange scheduled task exists
Your browser behaves differently
Security settings change unexpectedly

None of these things alone proves that your PC is infected.

But several occurring together deserve investigation.

If you suspect malware, run a Windows security scan and avoid opening or executing the suspicious file unnecessarily.

Don't Delete Unknown Files Too Quickly

This is one of the biggest mistakes people make.

You find a strange file.

You search its name online.

Someone says it's suspicious.

You delete it.

Then an application stops working.

The better approach is:

Identify → Investigate → Verify → Remove if necessary

First determine:

What is the file?
Where is it located?
When was it created?
What application owns it?
Is it running?
What launches it?
Does it appear again?
Does anything else unusual happen at the same time?

This gives you much more information than simply deleting it.

The Bigger Problem: You May Not Notice the Change Immediately

There is one limitation with manually investigating unknown files.

You usually discover them after the change has already happened.

You open File Explorer hours later and notice a new folder.

You don't know exactly when it appeared.

You don't know what process created it.

And you may have to reconstruct what happened from incomplete information.

This is where continuous system monitoring can be useful.

Instead of manually checking your PC every few hours, a monitoring tool can watch important system activity in the background and notify you when something unusual happens.

A Lightweight Way to Monitor Windows Activity

That's the idea behind SysPulse.

SysPulse is a lightweight Windows security monitor designed to keep an eye on important system activity in the background.

It can monitor things such as:

New processes
Startup changes
USB connections
CPU and RAM anomalies

It can also send Telegram alerts when monitored activity occurs.

The goal isn't to replace Windows security tools.

It's to give you another layer of visibility into what's happening on your computer, especially when you're not actively watching Task Manager.

You can learn more about it here:

SysPulse Website

Final Thoughts

Finding an unknown file or folder on Windows can be unsettling, but it doesn't automatically mean something malicious happened.

Windows and legitimate applications create files constantly.

The important part is understanding why the file appeared.

Start with:

Creation time
File location
File extension
Digital signature
Running processes
Startup programs
Scheduled tasks
Event Viewer
Recent software installations and updates

And if the same file keeps coming back, focus on finding the process or task that recreates it.

The most useful question isn't:

"Is this file suspicious?"

It's:

"What created this file, when did it happen, and what else was happening at the same time?"

Once you start looking at Windows activity as a sequence of events rather than isolated files, mysterious changes become much easier to investigate.

How to Check If Someone Is Remotely Accessing My Windows PC

Darkssel — Sat, 22 Aug 2026 02:24:51 +0000

You're working on your computer.

Suddenly, the mouse moves by itself.

A window opens — and closes — without you touching anything.

The cursor hovers over a file.

You freeze.

You might think:

"Is someone else controlling my PC right now?"

It's a terrifying thought.

And it's one of the most common security questions people search for.

The honest answer is this:

Most of the time, it's not a hacker.

It could be a glitch, a stuck key, or a background process.

But sometimes — it really is someone else.

This guide walks you through 7 ways to check if someone is remotely accessing your Windows PC — and what to do if you find evidence.

1. Check Active Remote Desktop Connections

Windows has built-in Remote Desktop Protocol (RDP).

If someone is connected to your PC remotely, you can see it.

How to check:

Press Win + R, type cmd, and press Enter
Type: query user
Look at the output

You'll see a list like this:

 USERNAME    SESSIONNAME    ID    STATE    IDLE TIME
 user1       console         1     Active    .
 user2       rdp-tcp#0       2     Active    .

If you see rdp-tcp# followed by a number, someone is connected via Remote Desktop.

What to do:

Log off the unknown user immediately
Change your password
Disable RDP if you don't need it

2. Look for Remote Support Software

Hackers often use legitimate remote support tools to access your PC.

Common ones include:

TeamViewer
AnyDesk
RemotePC
Chrome Remote Desktop
UltraViewer
LogMeIn
Ammyy Admin

How to check:

Open Task Manager (Ctrl + Shift + Esc)
Go to Processes and look for any of the above names
Also check the Startup tab for these programs

If you find any:

Check if they're running without your permission
Open the app and see if there's an active session
Uninstall them if you don't use them

Pro tip: Some malware uses the same names but is located in different folders. Check the file location by right-clicking in Task Manager → Open file location.

3. Check for Remote Access Services in Windows

Windows runs various services that enable remote access.

Some are legitimate. Some are not.

How to check:

Press Win + R, type services.msc, press Enter
Look for these services:

Remote Desktop Services (TermService)
Remote Access Connection Manager
Remote Procedure Call (RPC)
Remote Registry

What to do:

If Remote Desktop Services is running but you don't use RDP, stop and disable it
Right-click → Properties → Startup type → Disabled

Be careful: Don't disable RPC or RPC Locator — they're critical for Windows operation.

4. Check Network Connections for Suspicious Activity

Every remote connection uses your network.

You can see all active connections using a simple command.

How to check:

Open Command Prompt as Administrator
Run: netstat -an | findstr "ESTABLISHED"
Look for unfamiliar IP addresses or ports

Common remote access ports:

3389 — Remote Desktop Protocol (RDP)
5900 — VNC (Virtual Network Computing)
80, 443 — Web traffic (could be remote access via web)
5938 — TeamViewer
7070 — AnyDesk

If you see suspicious connections:

Note the IP address
Run: netstat -ano | findstr "ESTABLISHED" to see the PID (Process ID)
Open Task Manager → Details tab → match the PID to a process name

Example: If PID 1234 is connected to an unknown IP and it's running from C:\Users\...\svchost.exe (that's not the real Windows location), you may have found malware.

5. Check Windows Event Viewer for Remote Access Logs

Windows logs everything — including remote login attempts.

How to check:

Press Win + R, type eventvwr.msc, press Enter
Go to Windows Logs → Security
Look for these Event IDs:

4624 — Successful logon
4625 — Failed logon
4648 — Logon with explicit credentials

Filter for remote logons:

In Event Viewer, click Filter Current Log (right panel)
Enter Event ID 4624 in the filter box
Click OK

Look for logons with:

Logon Type 10 — RemoteInteractive (RDP)
Logon Type 3 — Network (network share)
Logon Type 2 — Interactive (local — ignore this)

If you see many 4624 events from unknown sources at odd hours, you may have a problem.

6. Check Task Scheduler for Suspicious Tasks

Attackers often create scheduled tasks that run remote access tools at regular intervals.

How to check:

Press Win + R, type taskschd.msc, press Enter
Look at Task Scheduler Library
Look for tasks with:

Unfamiliar names
Names that resemble Windows tasks but are slightly misspelled (svch0st, upd4te, etc.)
Tasks that run vnc.exe, teamviewer.exe, anydesk.exe, or cmd.exe with strange arguments

What to do:

Right-click and Disable any suspicious task
Do not delete — first research what it does

7. Run a Full Security Scan

Sometimes remote access tools are hidden by rootkits.

A good antivirus scan can detect them.

How to scan:

Open Windows Security (built-in)
Go to Virus & threat protection
Click Scan options
Select Full scan
Click Scan now

Alternative tools:

Malwarebytes — excellent at detecting remote access Trojans (RATs)
HitmanPro — second-opinion scanner
Kaspersky Virus Removal Tool — free and effective

Pro tip: Run scans in Safe Mode for better detection.

Hold Shift while clicking Restart
Go to Troubleshoot → Advanced options → Startup Settings → Restart
Press 4 for Safe Mode
Run your scans there

Summary Table

Symptom	What to Check	Action
Unknown user in `query user`	Active RDP session	Disconnect, change password
Remote support app running	TeamViewer, AnyDesk, etc.	Uninstall if not used
Suspicious network connection	`netstat -an`	Identify the process, kill it
Many 4624 Event IDs	Security log in Event Viewer	Investigate logon patterns
Unknown scheduled task	Task Scheduler	Disable and research
High CPU/network usage	Task Manager	Check for unknown processes

What If You Want to Monitor Remote Access Automatically?

Checking all of the above manually can be time-consuming.

You'd need to check:

Task Manager
Network connections
Event Viewer
Services
Startup items
Scheduled tasks

Every single time you feel suspicious.

That's why I built SysPulse — a lightweight Windows security monitoring tool.

SysPulse:

Monitors new processes in real-time
Sends Telegram alerts when unknown programs run
Tracks startup changes and scheduled tasks
Uses less than 30MB of RAM

You can set it up once and get instant alerts when anything changes on your system.

No more staring at Task Manager all day.

You can find it at: syspulse.pro

Final Thought

Remote access attacks are real.

But most of the time, that random cursor movement is just a stuck key or a driver glitch.

The key is to investigate before panicking.

Start with the simplest checks:

query user
Task Manager for remote support apps
netstat -an for suspicious connections

If you find something, disconnect your internet immediately and investigate.

If you're worried about being targeted, consider setting up a monitoring tool like SysPulse to watch for changes automatically.

Stay safe — and always question unexpected behavior.

Why Does My Windows PC Take So Long to Boot (And How to Fix It)?

Darkssel — Sat, 22 Aug 2026 02:14:49 +0000

You press the power button.

You wait.

The manufacturer logo appears.

You wait longer.

The spinning circle of dots appears.

You wait even longer.

Finally — after what feels like an eternity — your desktop loads.

You might think:

"Is this normal? Why does my PC take forever to start up?"

A slow boot isn't just annoying. It can be a sign that something is misconfigured, overloaded, or failing.

The good news is this:

Most slow boot issues can be fixed in under 10 minutes.

This guide covers 7 common reasons why Windows takes too long to start — and what you can do about each one.

1. Too Many Startup Programs

This is the #1 cause of slow boots.

Every application you install wants to start automatically when Windows boots.

Over time, you accumulate dozens of them.

Each one adds precious seconds to your boot time.

How to check:

Open Task Manager (Ctrl + Shift + Esc)
Go to the Startup tab
Look at the Startup Impact column

You'll see programs marked as:

High impact
Medium impact
Low impact

What to do:

Right-click and Disable any program you don't absolutely need at boot
Keep only essential items like your antivirus, graphics drivers, and maybe a cloud sync tool

Pro tip: You can usually disable Spotify, Adobe, Discord, Steam, and game launchers — they'll still run when you open them manually.

2. Too Many Windows Services

Even after you clean your startup apps, Windows services are still loading.

Many of these services are unnecessary for a typical user.

How to check:

Press Win + R, type msconfig, press Enter
Go to the Services tab
Check Hide all Microsoft services (important — don't disable critical Windows components)
Look at the remaining third-party services

What to do:

Uncheck any service you don't recognize or need
Be cautious — research a service before disabling it

Alternative: Use Task Manager → Services tab → Open Services (bottom) to get a full list with descriptions.

3. Slow or Failing Hard Drive

If your PC uses a mechanical hard drive (HDD), boot times can be naturally slower.

But if boot times have suddenly become slower, your HDD may be:

Fragmented
Nearly full
Showing signs of failure

What to do:

Open This PC → right-click your system drive (usually C:) → Properties → Tools → Optimize
For HDD: Run Defragment and Optimize Drives
For SSD: Run TRIM (the same tool will handle it automatically)

Check disk health:

Open Command Prompt as Administrator
Run: wmic diskdrive get status
If it says "OK", the drive is passing basic health checks
For deeper checks, use: chkdsk /f /r C: (requires a reboot)

Important: If your PC uses an SSD, defragmentation is unnecessary and can reduce its lifespan. Windows will recognize an SSD and use TRIM instead.

4. Fast Startup Is Disabled or Misconfigured

Windows has a feature called Fast Startup that saves system state to a file (hibernation) so your PC starts faster.

If this is disabled, your PC boots from scratch every time — which takes longer.

How to enable it:

Open Control Panel → Power Options
Click Choose what the power buttons do (left sidebar)
Click Change settings that are currently unavailable
Under Shutdown settings, check Turn on fast startup
Click Save changes

If the option is missing: You may need to enable hibernation first.

Open Command Prompt as Administrator
Run: powercfg /hibernate on
Restart and check again

5. Corrupt System Files

Windows system files can become corrupt over time.

This doesn't always cause blue screens — sometimes it just makes things slower.

How to check and repair:

Open Command Prompt as Administrator
Run: sfc /scannow
Wait for the scan to complete

If sfc finds issues but can't fix them:

Run: DISM /Online /Cleanup-Image /RestoreHealth
This may take 10–15 minutes
After it completes, run sfc /scannow again

Pro tip: Run these scans about once a month to keep your system healthy.

6. Outdated BIOS or UEFI Firmware

Your motherboard's firmware controls how hardware initializes during boot.

Outdated firmware can cause:

Slow POST (Power-On Self-Test) times
Compatibility issues with new hardware
Security vulnerabilities

What to do:

Visit your motherboard manufacturer's website
Check for BIOS/UEFI updates
Follow their instructions carefully

Important: Updating BIOS is riskier than updating drivers. Only do it if you're comfortable or if you're experiencing other hardware issues besides slow boot.

7. Not Enough RAM or Disk Space

When Windows boots, it loads essential files into RAM.

If your RAM is nearly full or your disk is almost full, this process slows down significantly.

Check RAM:

Open Task Manager → Performance → Memory
If you're using more than 80% of your RAM at idle, you may need more RAM

Check disk space:

Open This PC → check your system drive
If it's under 15–20% free space, consider cleaning up

Free up space:

Run Disk Cleanup (right-click drive → Properties → Disk Cleanup)
Click Clean up system files to remove old Windows updates
Uninstall unnecessary programs
Move large files (videos, game installations) to an external drive

Summary Table

Symptom	Likely Cause	Quick Fix
Many apps launch at boot	Startup programs	Disable in Task Manager > Startup
Black screen before Windows logo	BIOS/UEFI	Update firmware, check hardware
Long loading of user profile	Disk issues	Run `chkdsk`, free up space
Slow after login but not before	Services/startup items	Disable unnecessary services
Random delays during boot	Corrupt system files	Run `sfc /scannow`
Boot time varies each time	Fast Startup off	Enable Fast Startup

What If You Want to Monitor Boot Performance Automatically?

You can check boot times manually by looking at Task Manager → Startup tab → "Last BIOS Time" (displays in seconds). This shows how long your firmware took to initialize — useful for diagnosing hardware vs. software boot issues.

If you want more real-time system monitoring — including boot-time process tracking and alerts for new startup items — I built a lightweight Windows tool called SysPulse.

SysPulse:

Monitors startup changes automatically
Tracks CPU, RAM, Disk, and Network usage
Uses less than 30MB of RAM
Sends Telegram alerts when new processes start

You can find it at: syspulse.pro

Final Thought

A slow boot is rarely a mystery once you know where to look.

Most of the time, it's caused by too many startup programs or services.

Start with the easy fixes:

Disable unnecessary startup apps
Enable Fast Startup
Run Disk Cleanup
Scan for corrupt files

If none of those help, move to disk health checks and firmware updates.

The important thing is to test one change at a time so you know exactly what fixes the problem.

Happy booting!

Why Does My Windows PC Randomly Freeze or Stutter (When Nothing Is Running)?

Darkssel — Thu, 20 Aug 2026 02:22:09 +0000

You're typing a document, moving the mouse, or just watching a video.

Then it happens.

The cursor stutters.

The screen freezes.

Everything stops for a few seconds — or longer.

You wait. It comes back. Then it freezes again.

You might think:

"I'm not running anything heavy. So why is my PC suddenly freezing?"

Random freezes are one of the most frustrating Windows problems — and one of the most Googled.

The good news is this:

Windows rarely freezes "for no reason."

There's always a cause.

The challenge is finding it.

This guide walks you through 7 common reasons behind random freezes and stutters, with step-by-step fixes you can try right now.

1. Check CPU and Memory Usage First

You think you're not running anything.

But your computer may disagree.

Open Task Manager by pressing:

Ctrl + Shift + Esc

Then go to the Performance tab.

Look at CPU and Memory usage.

Ask yourself:

Is anything above 80–90%?

If CPU is high, click the Processes tab and sort by CPU usage.

Common hidden resource consumers include:

Web browsers with many open tabs
Game launchers downloading updates
Cloud sync tools (OneDrive, Google Drive)
Windows Update running in the background
Antivirus scans
Scheduled maintenance tasks

A short spike is normal.

But if usage stays high for several minutes, you've found a clue.

Quick fix: Right-click any unnecessary app in Task Manager and select End Task.

2. Check for Overheating

Modern CPUs and GPUs protect themselves from damage.

When temperatures rise above 85–90°C, they slow down automatically to cool off.

This is called thermal throttling.

It causes sudden stutters, micro-freezes, and lag — even when you're only on the desktop.

How to check:

Download a free tool like HWMonitor or Open Hardware Monitor
Check your CPU and GPU temperatures while idle and during light use

If temps are high:

Clean dust from fans and vents with compressed air
Move your PC to a hard surface (not a blanket or carpet)
Consider reapplying thermal paste (advanced users only)

A quick test: If freezes start after 10–15 minutes of use but not immediately after boot, overheating is likely.

3. Update or Roll Back Graphics Drivers

Your graphics driver connects Windows to your display.

A bad driver can cause:

Screen flicker
Mouse stutter
Full system freezes

How to update:

Right-click the Start button and select Device Manager
Expand Display Adapters
Right-click your GPU (NVIDIA, AMD, or Intel)
Select Update Driver → Search automatically for drivers

If the problem started after a recent update:

Right-click your GPU → Properties → Driver tab → Roll Back Driver

Alternatively, download the latest driver directly from NVIDIA, AMD, or Intel's website and perform a clean installation.

4. Test Your RAM

Faulty RAM can cause random freezes even during light tasks.

One bad memory sector can crash your entire system.

How to test:

Press Win + R, type mdsched.exe, and hit Enter
Select Restart now and check for problems

Windows will test your memory during reboot.

The scan takes 10–30 minutes.

If errors appear: You'll need to replace the faulty RAM stick.

Temporary workaround:

Reseat the RAM (remove and reinsert firmly)
Run with one stick at a time to isolate the bad module

5. Check Disk Health and Free Space

If your system drive (usually C:) is over 90% full, Windows struggles with:

Virtual memory (pagefile)
Temporary file storage
System restore points

A failing hard drive with bad sectors can also cause freezes when Windows tries to read corrupted data.

Clean up disk space:

Open This PC → right-click C: → Properties → Disk Cleanup
Click Clean up system files to remove old Windows updates
Uninstall unused apps and move large files to another drive

Check disk health:

Open Command Prompt as Administrator
Run: chkdsk /f /r C:
Press Y and restart your computer

Windows will scan and attempt to fix disk errors.

For SSD owners: Open your manufacturer's tool (Samsung Magician, Crucial Storage Executive, etc.) to check SSD health and update firmware.

6. Consider Malware or Heavy Antivirus Software

This may sound strange, but security software can sometimes cause instability.

Third-party antivirus suites (Norton, McAfee, 360 Total Security, etc.) often:

Inject themselves into every file operation
Scan files on every read and write
Run heavy background processes

When combined with Windows Defender already running, your system can slow down significantly.

What to do:

Run a full scan with Windows Security (built-in) or Malwarebytes (free)
If no threats are found, temporarily uninstall your third-party antivirus
Check if the stutters stop

For most users, Windows Defender is sufficient and lighter than most third-party options.

7. Disable Unnecessary Startup Programs and Services

Many applications you installed years ago are still running — silently consuming CPU, RAM, and disk I/O.

Disable startup apps:

Open Task Manager → Startup tab
Right-click and Disable anything you don't need immediately after boot (Spotify, Adobe, Discord, etc.)

Perform a Clean Boot (diagnostic mode):

Press Win + R, type msconfig, hit Enter
Go to the Services tab
Check Hide all Microsoft services (prevents disabling critical Windows components)
Click Disable all, then Apply → OK → Restart

If the stutter disappears, a third-party service was the culprit.

Re-enable services one by one to identify the exact offender.

Summary Table

Symptom	Likely Cause	Quick Fix

What If You Want to Monitor This Automatically?

Manually checking Task Manager, temperatures, disk health, and startup entries is repetitive.

If you're dealing with recurring freezes and want real-time monitoring without slowing down your system, I built a lightweight Windows tool called SysPulse.

SysPulse:

Tracks CPU, RAM, Disk, and Network usage in real time
Alerts you when processes spike or crash
Logs startup changes and background services
Uses less than 30MB of RAM — less than a single browser tab

No ads. No bloat.

It simply sits in your system tray and watches your PC's health, so you don't have to.

You can find it at: syspulse.pro

Final Thought

Random freezes and stutters are not a "Windows thing."

They're a "something is misconfigured or failing" thing.

Most of the time, fixing the issue takes 10 minutes or less — once you know where to look.

Start with the easiest fixes (Task Manager, Disk Cleanup) and work your way up.

And if you want a set-and-forget monitoring solution, consider SysPulse to catch issues before they freeze your workflow.
