Windows 11 Memory Integrity: Security Boost or Performance Killer?

Darkssel — Sat, 05 Sep 2026 15:34:30 +0000

You turn on your Windows 11 PC.

You launch your favorite game.

And suddenly, you notice lower FPS, stuttering, or a level of system overhead that wasn't there before.

Could Memory Integrity be part of the reason?

Microsoft is expanding the automatic enablement of Memory Integrity to more eligible Windows 11 devices starting in October 2026. The goal is to strengthen protection against attacks targeting the Windows kernel, but virtualization-based security can have a measurable performance impact on some systems, particularly in gaming workloads.

This guide explains what Memory Integrity is, what Microsoft is changing, how to check whether it is enabled, what performance testing has found, and whether disabling it is actually worth considering.

What Is Memory Integrity?

Memory Integrity, also known as Hypervisor-protected Code Integrity (HVCI), is a Windows security feature built on Virtualization-based Security (VBS).

Instead of relying entirely on the normal Windows kernel environment, VBS uses the Windows hypervisor to create an isolated environment for security-sensitive operations.

Memory Integrity uses that environment to protect kernel-mode code integrity.

In practical terms, it helps prevent malicious or untrusted kernel-mode code and drivers from modifying protected parts of Windows.

Think of it as an additional security boundary around one of the most sensitive parts of Windows.

Microsoft officially documents Memory Integrity as a VBS feature designed to strengthen protection against kernel-level attacks.

Why Is Microsoft Expanding Memory Integrity in October 2026?

Microsoft announced that Windows quality updates will begin enabling Memory Integrity on more eligible Windows devices starting in October 2026.

The rollout is gradual rather than a single switch that affects every Windows 11 PC at the same time.

Microsoft says Windows will evaluate device readiness before enabling the protection. Those readiness signals include factors such as:

Hardware capabilities
Compatibility
Performance considerations
Windows 11 system requirements
Existing security configuration

On some devices, enabling Memory Integrity will also enable the underlying Virtualization-based Security (VBS) environment if it is not already active.

Importantly, Microsoft says that existing administrator and user choices remain in effect. Devices where Memory Integrity was previously disabled will not automatically have it re-enabled by this particular rollout.

The goal is straightforward: make stronger kernel-level protection available on more compatible Windows systems without requiring users to configure it manually.

Does Memory Integrity Reduce Gaming Performance?

It can.

But there is no single percentage that applies to every PC or every game.

Performance depends on:

CPU architecture
Hardware virtualization support
Whether VBS is already active
Whether Memory Integrity/HVCI is enabled
The game being tested
Whether the workload is CPU-limited
Driver and software configuration

Microsoft specifically notes that Memory Integrity works more efficiently on processors with hardware features designed to accelerate virtualization security. Older processors may experience greater performance impact because they lack some of these capabilities.

What Do Independent Benchmarks Show?

Different tests have produced different results.

Tom's Hardware tested Windows 11 VBS/HVCI configurations and found an overall gaming performance impact around 5% on average in one set of tests, with individual games showing larger differences.

In another test using a high-end RTX 4090 system, Tom's Hardware found that VBS could make some games run up to around 15% slower, while many applications showed a much smaller difference.

Other independent testing has also found that the effect can vary considerably between games. For example, TechSpot recorded substantially larger changes in some titles when VBS was enabled, including noticeable differences in 1% low frame rates.

The important conclusion is:

Memory Integrity does not automatically cause a 5%, 10%, or 25% performance loss on every Windows 11 PC.

The effect is highly hardware- and workload-dependent.

For some systems, the difference may be barely noticeable.

For others, particularly certain CPU-limited gaming workloads, the impact can be more significant.

Why Can Older Hardware Be Affected More?

Modern processors include hardware capabilities that make virtualization-based security more efficient.

Microsoft specifically notes improved Memory Integrity performance on:

Intel processors with Mode-Based Execution Control (MBEC)
AMD Zen 2 and newer processors with Guest Mode Execute Trap (GMET) capabilities

Older processors may rely on additional software mechanisms instead of these hardware-assisted features, potentially increasing the performance overhead.

That does not mean every older processor will experience a large slowdown.

It means the architecture of the CPU is one factor that can influence the cost of Memory Integrity.

How to Check If Memory Integrity Is Enabled

Method 1: Windows Security

The easiest method is through Windows Security.

Open Windows Security
Select Device security
Select Core isolation details
Find Memory integrity

If the switch is On, Memory Integrity is enabled.

Method 2: System Information

You can also inspect the VBS status through Windows System Information.

Press Windows + R
Type:

msinfo32

Press Enter
Look for the Virtualization-based security entry

This can tell you whether VBS is running.

However, remember that VBS and Memory Integrity are related but not identical settings. VBS is the virtualization-based security platform; Memory Integrity/HVCI is one security feature that uses that platform.

How to Disable Memory Integrity

If you decide that you need to test your gaming performance with Memory Integrity disabled, Windows provides a built-in setting.

Step 1: Open Windows Security

Search for:

Windows Security

Open the application.

Step 2: Open Core Isolation

Go to:

Device security → Core isolation details

Step 3: Turn Off Memory Integrity

Find:

Memory integrity

Switch it to Off.

Windows may require a restart for the change to take effect.

Important Security Warning

Disabling Memory Integrity reduces protection against certain kernel-level attacks.

Microsoft recommends using these security protections where appropriate, and disabling them should not be treated as a universal gaming optimization.

If you disable the feature purely for troubleshooting or performance testing, consider re-enabling it afterward.

Should Gamers Disable Memory Integrity?

There is no universal answer.

Keep Memory Integrity Enabled If:

Security is your priority
You use the PC for work or sensitive information
You are not experiencing any meaningful performance problem
Your games run normally
You want stronger protection against kernel-level threats

Consider Testing With It Disabled If:

You are experiencing unexplained gaming performance problems
Your system is particularly sensitive to CPU overhead
You want to determine whether Memory Integrity is contributing to the problem
You understand the security trade-off

The best approach is not to assume.

Measure first.

Run the same game or benchmark with the same settings and compare the results.

Memory Integrity: Security vs. Performance

Aspect	Memory Integrity ON	Memory Integrity OFF
Kernel protection	✅ Stronger protection	⚠️ Reduced protection
Gaming performance	May have some overhead	Potentially lower overhead
Security posture	✅ Stronger	⚠️ Weaker
Best approach	Recommended when practical	Mainly for testing or specific performance needs
Performance impact	Varies by hardware/workload	Removes Memory Integrity overhead

The important point is that performance impact is not universal.

A modern PC may show only a small difference, while another configuration may show a more noticeable change in certain games.

How SysPulse Can Help You Monitor Your PC

If you are trying to determine why your Windows PC suddenly feels slower, changing a security setting is only one part of the investigation.

You also need to know what is happening on the system.

That's where SysPulse can be useful.

SysPulse is a lightweight Windows security monitor that runs in the background and sends Telegram alerts when important system activity changes.

It can help you monitor:

CPU and RAM anomalies — identify unusual resource usage
New processes — see when new processes appear, including their file paths
Startup changes — detect changes to Windows startup entries
USB connections — receive alerts when removable USB devices are connected
Telegram notifications — receive alerts when monitored events occur

SysPulse does not directly measure the gaming FPS impact of Memory Integrity, and it does not enable or disable Memory Integrity.

Instead, it gives you another layer of visibility into what is happening on your Windows PC when performance or system behavior changes.

A Better Way to Test Your PC

If you suspect Memory Integrity is affecting your gaming performance, don't rely on a single FPS number.

Try this:

Choose one game or benchmark.
Use the same graphics settings.
Run the same test several times.
Record average FPS.
Record 1% low FPS if your benchmark provides it.
Check CPU and RAM usage.
Compare the results with Memory Integrity enabled and disabled.
Re-enable the protection if you decide the performance difference is not worth the security trade-off.

This gives you evidence from your own hardware, which is much more useful than assuming that another person's benchmark applies to your PC.

Frequently Asked Questions

Is Memory Integrity the same as VBS?

No.

Memory Integrity, or HVCI, is a security feature that uses the Virtualization-based Security infrastructure.

VBS provides the isolated virtualization environment, while Memory Integrity uses that environment for kernel-mode code integrity protection.

Is Memory Integrity bad for gaming?

Not necessarily.

It can introduce performance overhead, but the size of that overhead varies substantially between hardware and games.

Does Memory Integrity always reduce FPS?

No.

Some systems and games show very small differences, while others can show more noticeable changes.

Will Microsoft enable Memory Integrity on every Windows 11 PC in October 2026?

No.

Microsoft says the October 2026 rollout targets eligible devices and will be gradual. Windows will evaluate device readiness before enabling the protection.

If I previously disabled Memory Integrity, will Windows automatically turn it back on?

Microsoft says that devices where Memory Integrity was previously disabled will not have it automatically re-enabled by this rollout.

Should I disable Memory Integrity permanently?

For most users, there is no reason to disable a security feature permanently just because it might have a performance cost.

If you are experiencing a real performance problem, test the difference on your own system first and make an informed decision.

Final Thoughts

Windows 11 Memory Integrity is not simply a "performance killer."

It is a legitimate security feature designed to make kernel-level attacks harder.

At the same time, performance overhead is real in some configurations, particularly in certain gaming workloads.

The most accurate answer is therefore not:

"Memory Integrity costs 10% FPS."

It is:

"The performance impact depends on your hardware, software, and workload."

Microsoft's October 2026 expansion means more Windows 11 users may encounter the feature, so understanding how to check it—and how to measure its actual impact on your own PC—is more useful than relying on a single benchmark number.

If your PC suddenly behaves differently, monitor the system, measure the performance, and make security decisions based on evidence rather than assumptions.

Stay secure — and keep your system measurable.

How to Find Hidden Scheduled Tasks on Windows (Before They Become a Security Risk)

Darkssel — Fri, 04 Sep 2026 09:24:50 +0000

You open Task Manager. You check Startup programs. Nothing looks suspicious.

But malware doesn't always need to show up in Startup.

Sometimes, it hides in a place most users rarely check — the Windows Task Scheduler.

Attackers abuse scheduled tasks for persistence, allowing malicious programs to run automatically when a system starts, a user logs in, or a specific trigger occurs. Some tasks are deliberately hidden or made difficult to spot through normal Task Scheduler views.

So the question is: How can you investigate scheduled tasks and look for suspicious or hidden persistence on Windows?

This guide walks through several ways to inspect scheduled tasks and explains what to look for when something doesn't seem right.

Why Scheduled Tasks Are a Favorite Target for Malware

Scheduled tasks are a legitimate Windows feature. Windows and installed applications use them for updates, maintenance, backups, telemetry, cleanup, and other normal operations.

The problem is that attackers can abuse the same mechanism for persistence.

A malicious task might launch a program:

When Windows starts
When a user logs in
At a specific time
Every few minutes or hours
After another system event occurs

Common Abuse Techniques

Technique	How It Works
`schtasks.exe` abuse	Malware uses the built-in `schtasks.exe` utility to create or modify scheduled tasks
Task Scheduler APIs	Software interacts with Task Scheduler programmatically instead of using the command line
High-privilege tasks	A task may be configured to run with elevated privileges, making suspicious configurations important to investigate
Obfuscated or misleading names	Attackers choose names that resemble legitimate Windows or software components
Hidden or difficult-to-enumerate tasks	Attackers manipulate task metadata or permissions to make persistence harder to discover

The important point is that not every suspicious task is malware, and not every hidden-looking task is malicious. Windows and legitimate applications create many tasks that users may not recognize.

The goal is to investigate unusual behavior rather than automatically delete anything unfamiliar.

7 Ways to Find Suspicious or Hidden Scheduled Tasks

Method 1: Check Task Scheduler GUI

The Task Scheduler GUI is the easiest place to start. It provides a visual way to inspect scheduled tasks and their triggers, actions, and security settings.

How to open it:

Press Win + R
Type taskschd.msc
Press Enter
Select Task Scheduler Library
Browse the available tasks and subfolders

Red flags to investigate:

Tasks with random or misleading names
Tasks launching executables from Temp or unusual AppData locations
Tasks executing scripts from unexpected directories
Tasks running at user logon or system startup without an obvious reason
Tasks with unusual triggers
Tasks that recently appeared or point to files that no longer exist

For example, a task launching C:\Users\Public\Documents\updater.exe deserves investigation if you don't recognize the associated software.

Important limitation: The Task Scheduler GUI is useful, but it should not be treated as proof that everything on the system has been discovered. Attackers can manipulate task-related configuration, permissions, or other system components to make persistence harder to identify.

Method 2: Use PowerShell

PowerShell provides a convenient way to enumerate registered scheduled tasks.

Basic enumeration:

Get-ScheduledTask | Select-Object TaskName, State, TaskPath

Detailed inspection:

Get-ScheduledTask | Select-Object TaskName, TaskPath, State, Actions, Triggers

With execution history:

Get-ScheduledTask | ForEach-Object {
    $task = $_
    $info = $task | Get-ScheduledTaskInfo
    [PSCustomObject]@{
        TaskName = $task.TaskName
        TaskPath = $task.TaskPath
        State    = $task.State
        LastRun  = $info.LastRunTime
        NextRun  = $info.NextRunTime
    }
}

What to investigate:

Unknown task names
Unexpected task paths
Recently created tasks
Tasks executing unusual programs or scripts from temporary directories
Unexpected logon or startup triggers
Tasks configured to run with elevated privileges

PowerShell is powerful, but Get-ScheduledTask is an enumeration method, not a guarantee that every form of persistence will be exposed.

Method 3: Use the schtasks Command

Windows includes the schtasks.exe command-line utility for investigating scheduled tasks.

List tasks with detailed information:

schtasks /query /fo TABLE /v

List-style output:

schtasks /query /fo LIST /v

What to look for:

Task names
Task paths
Run times
Next scheduled runs
Run-as accounts
Task status
Actions and commands

Investigate tasks that have unusual names, run from suspicious directories, execute unknown scripts or programs, run with unexpectedly high privileges, trigger at logon or startup, or appear to have been created recently.

Like the GUI and PowerShell, schtasks should not be considered a complete forensic solution. Different persistence techniques can be difficult to discover through normal task enumeration.

Method 4: Inspect the Task Files on Disk

Windows stores task definitions under C:\Windows\System32\Tasks.

How to inspect:

Open File Explorer
Navigate to C:\Windows\System32\Tasks
Browse directories and look for task files you don't recognize
Compare suspicious entries with what you see in Task Scheduler and PowerShell
Inspect a task definition using a text editor

A task definition may contain information about commands, executables, triggers, users, run levels, and conditions.

For example, an entry containing an unexpected executable like this would be worth investigating:

<Exec>
    <Command>C:\Users\Public\Documents\updater.exe</Command>
</Exec>

Important warning: Do not delete task files simply because their names look unfamiliar. Many legitimate Windows components and third-party applications use obscure-looking names. First identify what created the task and what executable it launches.

Method 5: Use Microsoft Sysinternals Autoruns

For a broader persistence investigation, Autoruns from Microsoft Sysinternals is a useful tool. It examines many different locations where applications can configure automatic execution, including scheduled tasks.

How to use it:

Download Autoruns from Microsoft Sysinternals
Run it as Administrator
Open the Scheduled Tasks section
Review unfamiliar entries
Investigate their executable paths and publishers

Useful things to examine include unknown publishers, missing files, suspicious executable paths, programs running from temporary directories, recently installed software, and tasks with unusual names.

The Hide Microsoft Entries option can make third-party entries easier to review. However, don't assume every remaining entry is malicious—a third-party application can be completely legitimate.

Method 6: Inspect Task Scheduler's Registry Data

Windows maintains Task Scheduler metadata in the registry. Two important locations include:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree

How to inspect it:

Press Win + R, type regedit, press Enter
Navigate to the TaskCache locations above
Compare suspicious entries with known scheduled tasks

You may encounter GUID-style task identifiers under the Tasks key and task names or paths under the Tree key.

What to look for:

Entries that don't correspond to known tasks
Unexpected task names
Suspicious task relationships
Recently introduced entries
References associated with unusual executables

Registry inspection is an advanced technique. Do not delete registry entries unless you are certain what they belong to. Removing Task Scheduler registry data incorrectly can break legitimate Windows tasks.

Method 7: Monitor New Scheduled Task Activity

Finding suspicious scheduled tasks after the fact is useful, but detecting changes as they happen is even more valuable. If a new persistence mechanism appears on your PC, you ideally want to know about it soon rather than discovering it weeks later.

Useful monitoring can include:

New scheduled task creation
Changes to existing tasks
New processes launched by scheduled tasks
Startup configuration changes
Unexpected resource usage

No single monitoring technique sees everything. Scheduled Task monitoring, process monitoring, startup monitoring, and other security controls complement each other.

How SysPulse Can Help

Manually checking Task Scheduler, PowerShell, registry entries, and task files can be time-consuming. That's where SysPulse can provide an additional layer of visibility.

SysPulse is a lightweight Windows security monitor that watches for important system changes and sends Telegram alerts. It does not directly inspect or parse every scheduled task. Instead, some activity resulting from scheduled-task persistence can be visible through the areas SysPulse monitors.

New Process Detection

If a suspicious scheduled task launches an executable, SysPulse can detect the resulting new process and report:

Process name
Full executable path
Resource usage
Detection time

For example, if a task launches an unfamiliar executable from an unusual directory, the process alert gives you an important clue about where that program is located.

Startup Monitoring

SysPulse also monitors Windows startup entries. This is separate from Task Scheduler, but it can provide another useful persistence signal when malware modifies startup configuration.

Resource Monitoring

SysPulse monitors CPU, RAM, and disk activity. If an unexpected background process starts consuming significant resources, this provides another clue that something deserves investigation.

Telegram Alerts

Instead of requiring you to manually check the computer, SysPulse sends security alerts to Telegram when monitored activity changes. The goal isn't to replace antivirus software or perform full malware analysis—it's to provide real-time visibility into important system activity.

SysPulse runs quietly in the background and uses less than 30 MB of RAM.

Summary Table

Method	Tool	Best For	Complete Detection?
Task Scheduler GUI	`taskschd.msc`	Quick visual inspection	❌ No
PowerShell	`Get-ScheduledTask`	Command-line enumeration	❌ No
schtasks	`schtasks /query`	Detailed CLI output	❌ No
Task files	`C:\Windows\System32\Tasks`	Inspecting stored task definitions	❌ No
Autoruns	Microsoft Sysinternals	Broader persistence investigation	❌ No
Registry	TaskCache	Advanced investigation	❌ No
SysPulse	Telegram alerts	Real-time process/startup/resource monitoring	⚠️ Complementary

No single method should be treated as a complete scheduled-task security solution. Combining several sources gives you a much better picture.

Common Suspicious Scheduled Task Scenarios

Scenario	What to Investigate	Recommended Response
Task launches a file from Temp	Unknown executable or script	Identify and verify the file
Task launches from unusual AppData location	Unknown software	Check publisher, signature, and file reputation
Task runs at user logon	Whether the task is legitimate	Identify the program and creator
Task runs every few minutes	Unexpected recurring activity	Investigate the command and executable
Task has a misleading name	Possible masquerading	Compare its action with legitimate Windows components
Task appeared without explanation	Possible unauthorized persistence	Investigate the task, executable, and recent system changes

Don't Assume Suspicious Means Malicious

This is extremely important. Windows itself creates many scheduled tasks, and legitimate applications frequently create their own. A task named something unfamiliar does not automatically mean your PC is infected.

Before disabling or deleting a task, investigate:

What executable does it launch?
Where is that executable located?
Is the file digitally signed?
Which software installed it?
When was the task created?
Does its behavior match legitimate software?

What If You Find a Truly Suspicious Task?

If you find a scheduled task that clearly appears malicious, don't immediately delete everything associated with it.

First collect information:

Task name
Task path
Action/command
Executable path
Trigger
User account
Creation or modification information
Digital signature of the executable

Then investigate the executable itself. If malware is suspected, use a reputable antivirus or endpoint security solution for a full scan. If you believe an account has been compromised, change affected passwords from a trusted device and enable multi-factor authentication where possible.

Final Thoughts

Scheduled Tasks are a legitimate and powerful Windows feature, but they can also be abused for persistence.

If you're investigating suspicious activity, don't rely on only one place. Start with:

Task Scheduler
PowerShell
schtasks
C:\Windows\System32\Tasks
Microsoft Sysinternals Autoruns
Task Scheduler registry data

Discovering a suspicious task is only the beginning. The most important question is: What does the task actually execute, and is that program legitimate?

For ongoing visibility, a combination of process monitoring, startup monitoring, resource monitoring, and traditional security software provides broader coverage than any single technique.

SysPulse adds lightweight real-time visibility to Windows by monitoring processes, startup changes, USB connections, and unusual resource activity while sending alerts directly to Telegram.

Know what is happening on your PC before a suspicious change becomes a bigger problem.

Stay secure!

How to Check Which Apps Are Sending Your Data Over the Internet on Windows

Darkssel — Wed, 02 Sep 2026 23:58:51 +0000

You open your browser. Everything seems normal.

But behind the scenes, dozens of applications might be quietly sending data over the internet — without you knowing.

Game launchers checking for updates. PDF readers pinging analytics servers. System services phoning home. Even some antivirus tools regularly send data to the cloud.

Most of this is legitimate. But some of it might not be.

The question is: How do you find out exactly which apps are using your internet connection?

This guide covers 6 practical ways to check which apps are sending your data over the internet on Windows — from built-in Windows tools to powerful third-party utilities.

Why You Should Care About App Network Activity

Understanding which apps use your internet connection matters for several reasons:

Reason	Why It Matters
Privacy concerns	Some apps send more data than they should — including personal information
Data caps	Background data usage can eat through your monthly limit without you noticing
Security risks	Malware often communicates with remote servers to exfiltrate data or receive commands
Performance issues	Apps consuming bandwidth can slow down your entire network
Suspicious behavior	Unknown processes making unexpected connections are a red flag

The good news? Windows provides several built-in tools to monitor this activity. And if you need more detail, there are excellent third-party options as well.

Method 1: Data Usage in Windows Settings

The simplest way to see which apps are using your internet is through Windows Settings.

How to check:

Press Win + I to open Settings
Go to Network & Internet → Data usage
Review the usage breakdown by app

What you'll see: A list of apps and the amount of data they've used over the selected period. The available breakdown and filtering options may vary depending on your Windows version and connection type.

Best for: A quick overview of which apps are consuming the most data over time.

Limitation: This shows historical usage, not real-time activity.

Method 2: Task Manager (Real-Time Monitoring)

For real-time network activity, Task Manager is your friend.

How to check:

Press Ctrl + Shift + Esc to open Task Manager
Go to the Processes tab
Right-click any column header and select Network from the dropdown
Sort by Network usage to see the most active apps at the top

What you'll see: Which processes are actively using your internet connection right now, with the amount of data they're sending or receiving.

Best for: Seeing which apps are actively using your internet connection right now.

Limitation: Only shows current activity, not historical patterns.

Method 3: Resource Monitor (Detailed Process-Level View)

For granular, process-level visibility into network activity, Resource Monitor is one of the most useful built-in tools.

How to check:

Open the Start Menu and type Resource Monitor
Click "Resource Monitor" in the search results to launch it
Switch to the Network tab
In the Processes with Network Activity section, you'll see all processes using the network

What you can see:

Image: The process name and path
PID: Process ID
Send (B/sec): Data being sent per second
Receive (B/sec): Data being received per second
Total (B/sec): Total bandwidth usage

You can also expand the TCP Connections section to see the remote IP addresses and ports each app is connecting to.

Best for: Deep investigation of which specific processes are using bandwidth and where they're connecting.

Limitation: Requires some technical knowledge to interpret the data.

Method 4: netstat Command (Advanced Users)

For users comfortable with the command line, netstat provides detailed information about all active network connections.

How to check:

Open Command Prompt or PowerShell as Administrator
Run this command to see all established connections with Process IDs:


netstat -ano | findstr ESTABLISHED

What each flag does:

-a: Shows all connections and listening ports
-n: Displays addresses and ports in numerical form
-o: Shows the owning process ID (PID)

To identify which app is using a specific connection:

Note the PID from the netstat output
Open Task Manager → Details tab
Find the process with that PID

For a more detailed view with process names:


netstat -b

(May require Administrator privileges depending on your system configuration)

Best for: Power users who want to see every single network connection in detail.

Limitation: Command-line interface isn't user-friendly for everyone.

Method 5: Portmaster — Application-Level Network Monitoring

If you want full visibility and control over every outbound connection, Portmaster is a strong free option.

Portmaster is a free, open-source application-layer firewall that shows every outbound connection an app makes and gives you the power to block it.

Key features:

Feature	Description
App-level visibility	Shows exactly which app is trying to connect, not just an IP or port
Real-time monitoring	Live-updating interface that lists every connection
Tracker blocking	Identifies and blocks known trackers, ad servers, and malware domains
Secure DNS	Uses encrypted DNS lookups instead of Windows' default DNS
Per-app rules	Set permanent allow/block rules for each application
Connection details	Shows the destination domain name and whether it's a known tracker

Once installed, Portmaster runs in the background monitoring outbound traffic. You'll see exactly which apps are "phoning home" — often more than you'd expect.

Best for: Privacy-conscious users who want full control over app network access.

Limitation: Requires some initial setup and decision-making about which apps to allow or block.

Method 6: TCPView and GlassWire

TCPView (Microsoft Sysinternals)

TCPView is a free tool from Microsoft's Sysinternals suite that provides a graphical representation of all TCP and UDP endpoints on your system.

How it works:

Lists all active TCP and UDP endpoints
Shows local and remote addresses
Displays connection states
Reports the owning process name
Updates in real-time (default: every second)
Color-coded: new endpoints in green, closed in red

You can even close established connections directly from the interface.

Note: Closing a connection does not necessarily stop the application from reconnecting. Use this feature for temporary investigation, not as a permanent solution.

Best for: Quick, visual inspection of all active network connections with process information.

Limitation: Doesn't show historical data — only current connections.

GlassWire

GlassWire is a popular network monitor with visual traffic graphs and application-level firewalling.

Key features:

Visual traffic monitoring with graphs
Breakdown by application, host, and traffic type
Built-in firewall controls
VirusTotal integration
Helps identify unusual network activity

Best for: Users who prefer visual, easy-to-understand network monitoring.

Limitation: Free version has some limitations compared to the paid version.

How to Identify Suspicious Activity

Regardless of which tool you use, here's what to look for:

Red Flag	What It Means
Unknown process names	If you don't recognize the process, investigate it
Connections to unfamiliar domains	Check if the destination is legitimate
Apps sending data when idle	Background activity when you're not using the app may be worth investigating, though many legitimate apps also perform background updates
High bandwidth usage	Apps consuming significant bandwidth without clear purpose
Repeated connections to an unfamiliar server	Worth investigating, especially if the process or destination is unknown

If you find something suspicious:

Note the process name and file path
Check the digital signature (right-click file → Properties → Digital Signatures)
Search the process name online
Upload suspicious files to VirusTotal for analysis, but avoid uploading files containing sensitive or private information

How SysPulse Can Help

Tools like Task Manager, Resource Monitor, and netstat are excellent for checking network activity at specific moments. But they don't alert you when something changes.

That's why I built SysPulse — a lightweight Windows security monitor that runs silently in the background and sends you Telegram alerts when monitored system activity changes.

Note: SysPulse monitors processes, startup changes, USB connections, and resource usage — it does not directly monitor network traffic. It's designed to help you stay aware of system changes that could indicate suspicious activity.

SysPulse can:

Detect new processes — Every time an executable launches, SysPulse logs the name and full file path
Monitor CPU and RAM anomalies — Get alerts when resource usage exceeds your thresholds
Detect USB connections — Know instantly when someone plugs a USB drive into your PC
Detect startup changes — Be alerted when a program adds itself to startup
Send Telegram alerts — Get instant notifications even when you're away from your desk

SysPulse runs silently in the background, uses less than 30MB of RAM, and never touches your personal files — it watches system behavior, not your data.

You can find it at: syspulse.pro

How to Tell If Your Windows PC Has Been Hacked (11 Warning Signs)

Darkssel — Wed, 02 Sep 2026 23:40:44 +0000

You close your laptop. You walk away.

When you come back, the mouse is in a different position.

A program you didn't open is running.

Your passwords stop working.

You might think:

"Has my PC been hacked?"

It's a terrifying thought. But the truth is, hackers don't always leave obvious traces. Sometimes the signs are quiet — a slightly slower system, a network connection you don't recognize, a webcam light that flickers for no reason.

The good news? Hackers leave footprints. You just need to know where to look.

This guide covers 11 warning signs that your Windows PC may be hacked — plus exactly what to do if you find evidence.

11 Signs Your Windows PC May Be Hacked

1. Your Mouse Moves or Clicks on Its Own

If your cursor moves, clicks, or selects things without your input — that's a potential sign of remote access, especially if clicks or actions happen without your input. However, hardware issues (faulty mouse, driver problems, touchpad glitches) or Bluetooth interference can also cause similar behavior.

What to do:

Unplug your Ethernet cable and turn off Wi-Fi
Check for remote access software (TeamViewer, AnyDesk, Chrome Remote Desktop)
Run a full malware scan

2. Programs Open or Close Unexpectedly

If windows pop up, close, or switch without you touching anything, this can be a sign of remote access, but software bugs, automation tools, or other Windows issues can cause similar behavior.

What to do:

Open Task Manager (Ctrl + Shift + Esc) and look for unfamiliar processes
Check the Startup tab for unknown entries
Look for programs you don't recognize in Installed apps (Settings → Apps)

3. Security Software Is Disabled Unexpectedly

If your security software turns off without you doing it, that's a red flag — but it's not always a hack. Windows Defender can automatically disable itself when another antivirus product is installed and active. This is expected behavior. However, if you don't have another antivirus installed and Defender is off, investigate immediately.

How to check:

Open Windows Security (search "Windows Security" in Start)
Go to Virus & threat protection
Check if Real-time protection is On

If it's off, you didn't turn it off, and no other antivirus is active — that's a sign worth investigating.

4. Unusual Network Activity When Idle

Hackers need to communicate with their command servers. If your network light keeps flashing when you're not doing anything, something may be sending data out.

How to check:

Method 1: Resource Monitor

Open Task Manager → Performance tab
Click Resource Monitor → Network tab
Look for processes you don't recognize sending data

Method 2: netstat command

Open Command Prompt as Administrator
Run: netstat -ano | findstr ESTABLISHED
Look for connections to IP addresses you don't recognize
Cross-reference the PID (Process ID) in Task Manager's Details tab

Important: Don't assume a connection is malicious just because it uses a particular port. Common ports can be used by completely legitimate software. Focus on the process, remote address, connection state, and whether you recognize the application.

Pro tip: Paste suspicious IP addresses into VirusTotal — it checks against 90+ security vendors.

5. Your PC Is Suddenly Slower Than Usual

Malware runs in the background, consuming CPU, memory, and disk resources. If your computer suddenly feels sluggish — even when nothing is open — something may be running without your knowledge.

How to check:

Open Task Manager (Ctrl + Shift + Esc)
Go to the Processes tab
Sort by CPU, Memory, or Disk usage
Look for unknown processes consuming high resources

A slow computer isn't always a hacked computer — it could be a dying hard drive or too many browser tabs. But if you see unknown processes using resources, investigate further.

6. Unauthorized Account Activity

If you see unexpected password reset emails, strange posts on your social media, or friends receiving spam from your accounts, your credentials may have been stolen.

What to do:

Check your email for unexpected security alerts
Review login history for your important accounts
Check for unfamiliar devices or IP addresses in account settings
Immediately change passwords from a different, trusted device
Enable two-factor authentication (2FA) wherever possible

7. Your Webcam Light Turns On Unexpectedly

If your webcam indicator light turns on when you're not using it — that's a red flag.

What to do:

Close all video apps (Zoom, Teams, Chrome, etc.)
Check which apps have camera access: Settings → Privacy & security → Camera
If the light stays on, run a full malware scan immediately

8. New User Accounts You Didn't Create

Hackers often create backdoor accounts to maintain access.

How to check:

Open Settings → Accounts → Other users (or Family & other users)
Look for accounts you don't recognize
Also check Control Panel → User Accounts

If you find an unknown account: Disconnect from the internet, remove the account, and change your passwords.

9. Browser Home Page or Search Engine Changed

Malware often hijacks your browser settings — changing your home page, search engine, or installing extensions without your permission.

How to check:

Chrome: chrome://extensions/
Edge: edge://extensions/
Firefox: about:addons

Look for:

Extensions you didn't install
Home page or search engine changed
Unexpected toolbars or add-ons

What to do: Remove any extension you don't recognize. Reset your browser settings if needed.

10. Suspicious Files or Programs You Didn't Install

If you find files you don't recognize — especially in C:\Users\[YourName]\AppData\Local\Temp\ or other unusual locations — they could be malware.

How to check:

Open Task Manager → look for suspicious processes
Right-click → Open file location
If the file is in Temp, AppData, or another unusual location — investigate further

Important: Files in Temp or AppData are not automatically malicious — many legitimate applications use these locations. Investigate the file's publisher, digital signature, process, and behavior before drawing conclusions.

Pro tip: Check the digital signature: Right-click the file → Properties → Digital Signatures. Legitimate software from trusted vendors will have a valid signature. If there's no signature or it's invalid, that's a red flag.

11. Your PC Wakes Up by Itself

If your computer wakes from sleep or hibernation without you touching it, it's worth investigating. A PC waking by itself does not automatically mean someone is remotely accessing your computer — it can also be caused by scheduled tasks, USB devices, network adapters, or wake timers.

How to check:

Open Command Prompt as Administrator
Run: powercfg -lastwake — this shows what woke your PC last
Also run: powercfg -waketimers — this shows scheduled wake timers
Check Event Viewer: Windows Logs → System → filter by Power-Troubleshooter

What to Do If You Find Evidence of a Hack

Step 1: Disconnect from the Internet Immediately

Unplug your Ethernet cable and turn off Wi-Fi. This cuts off the hacker's communication with your PC.

Step 2: Run a Full Malware Scan

Open Windows Security → Virus & threat protection
Click Scan options → Full scan → Scan now
For a second opinion, run Malwarebytes (free)

Step 3: Check for Remote Access Software

Look for programs like TeamViewer, AnyDesk, LogMeIn, or RemotePC in your installed apps. If you didn't install them, uninstall them.

Step 4: Change Your Passwords

From a different, trusted device, change passwords for:

Email accounts
Banking and financial accounts
Social media
Any account that may have been compromised

Step 5: Enable Two-Factor Authentication

Turn on 2FA for all important accounts to prevent future unauthorized access.

Step 6: Remove Suspicious Programs

Open Settings → Apps → Installed apps
Sort by installation date (newest first)
Uninstall anything you don't recognize

Step 7: Check Startup Programs and Scheduled Tasks

Task Manager → Startup tab — disable unknown entries
Press Win + R, type taskschd.msc → check for unfamiliar scheduled tasks

Step 8: Consider a Fresh Install (Last Resort)

If you can't fully clean the system, consider reinstalling Windows. Back up your important files first, then perform a clean installation.

How SysPulse Can Help Detect Hacks Early

Checking for all 11 signs manually is time-consuming. You'd have to:

Check Task Manager every day
Monitor network connections
Review startup programs
Check for new user accounts
Watch for USB devices

That's exactly why I built SysPulse — a lightweight Windows security monitor that watches for suspicious activity and sends you Telegram alerts the moment something changes.

SysPulse can:

Detect new processes — Every time an executable launches, SysPulse logs the name and full file path. If a suspicious process appears, you'll know immediately.
Monitor CPU, RAM, and Disk anomalies — Get alerts when resource usage exceeds your thresholds.
Detect USB connections — Know instantly when someone plugs a USB drive into your PC.
Detect startup changes — Be alerted when a program adds itself to startup.
Send Telegram alerts — Get instant notifications even when you're away from your desk.

SysPulse runs silently in the background, uses less than 30MB of RAM, and never touches your personal files — it watches system behavior, not your data.

You can find it at: syspulse.pro

Windows 11 Microphone Not Working? Here's How to Fix It

Darkssel — Wed, 02 Sep 2026 10:04:50 +0000

You join a Zoom meeting.

You say "Hello."

Nobody responds.

You type in the chat: "Can you hear me?"

They can't.

You check your microphone. The settings look fine. But still — no sound.

You might think:

"Is my mic broken? Do I need to buy a new headset?"

Probably not.

Microphone problems are a common Windows 11 issue. They can happen after a Windows update, a driver conflict, a privacy setting change, or just randomly.

The good news? Many microphone issues can be fixed without buying new hardware.

This guide covers 10 practical ways to fix microphone problems on Windows 11 — from simple checks to driver updates.

Why Is My Microphone Not Working on Windows 11?

Microphone problems can happen for many reasons:

Go to the Enhancements tab
Check Disable all enhancements
Click Apply → OK

Fix 9: Check for Conflicting Apps

If another app is actively using or has locked access to the microphone, your current app may not be able to use it.

How to check:

Close all apps that might be using the microphone (Zoom, Teams, Chrome, Discord, etc.)
Open Task Manager → Processes tab
Look for any app that might be using the mic
Right-click → End Task only on apps you recognize that may be using the microphone
Restart your app and test the microphone

Pro tip: Some apps (like antivirus software) can also block microphone access. Check your security software's privacy or microphone-protection settings before disabling it entirely.

Fix 10: Run SFC and DISM

Corrupted system files can cause microphone issues.

How to run SFC and DISM:

Open Command Prompt as Administrator
Run:


DISM /Online /Cleanup-Image /RestoreHealth

Wait for completion

How to disable in Windows:

Settings → System → Display → Graphics
Click Change default graphics settings
If the option is available, toggle Hardware-accelerated GPU scheduling to Off
Restart your PC

Fix 8: Check HDR Settings

HDR (High Dynamic Range) can sometimes cause washed-out colors or display issues.

How to check and adjust:

Settings → System → Display
Under HDR, toggle HDR to Off (temporarily)
Check if the display looks normal

If HDR is causing issues:

Update your graphics driver
Check if your monitor supports HDR
Use the Calibrate HDR tool in Windows Settings

Fix 9: Run SFC and DISM

Corrupted system files can cause display issues.

How to run SFC and DISM:

Open Command Prompt as Administrator
Run:


DISM /Online /Cleanup-Image /RestoreHealth

Wait for completion
Run:


sfc /scannow

Wait for completion
Restart your PC

Pro tip: This fixes many system-wide issues, not just display problems.

Fix 10: Adjust Power Settings

Power-saving modes can throttle your GPU, causing display issues.

How to adjust power settings (Windows 11):

Open Settings → System → Power & battery
Under Power mode, select Best performance (if available)
If you're using a laptop, plug it in before selecting Best performance

Alternative (if Power & battery is not available):

Search Power Options in the Start menu
Select High Performance (if available)
If you don't see it, click Show additional plans

Note: On laptops, this may reduce battery life — use only when plugged in.

Windows 11 Taskbar & Start Menu Not Working? Here's How to Fix Them

Darkssel — Wed, 02 Sep 2026 04:19:10 +0000

You click on the Start button.

Nothing happens.

You try to click on a taskbar icon. No response.

You right-click on the taskbar—the menu appears, but nothing else works.

You might think:

"Is my PC broken? Do I need to reinstall Windows?"

Probably not.

Taskbar and Start menu issues are among the most frustrating problems in Windows 11. They can happen after an update, a corrupted system file, or a glitch in Windows Explorer.

The good news? Many taskbar and Start menu issues can be fixed without reinstalling Windows.

This guide covers 9 practical ways to fix taskbar and Start menu problems on Windows 11 — from simple restarts to advanced repairs.

Why Is My Taskbar or Start Menu Not Working on Windows 11?

Taskbar and Start menu problems can happen for many reasons:

Cause	Description
Windows Explorer crash	The process that manages the taskbar and Start menu has crashed or is stuck
Corrupt system files	Damaged Windows components
Windows updates	Some updates break UI elements temporarily
Corrupt user profile	Your user profile may be damaged
Background apps	Some apps can interfere with the taskbar
Registry issues	Incorrect or corrupt registry settings
Malware	Malware can block or disable the taskbar
Outdated drivers	Graphics or display drivers can cause UI glitches

9 Ways to Fix Taskbar and Start Menu Problems

Fix 1: Restart Windows Explorer

This is the simplest fix — and it often works immediately.

When Windows Explorer crashes or hangs, the taskbar and Start menu stop responding.

How to do it:

Press Ctrl + Alt + Del → click Task Manager
Go to the Processes tab
Find Windows Explorer (or explorer.exe)
Right-click → Restart

What happens: The taskbar, desktop icons, and Start menu will reload. This often resolves temporary glitches.

Alternative: Press Win + R, type explorer.exe, press Enter.

Pro tip: If you can't open Task Manager, press Ctrl + Shift + Esc directly.

Fix 2: Restart Your PC

A full restart can fix temporary issues that cause taskbar and Start menu problems.

How to do it:

Click Start → Power → Restart
Wait for your PC to reboot
Check if the taskbar and Start menu work

Note: Choose Restart — not Shutdown. Windows Fast Startup can sometimes prevent drivers from reloading properly.

Fix 3: Restart the Start Menu Process (Advanced)

If the Start menu is the only issue, restarting its process can help.

How to do it:

Open Task Manager (Ctrl + Shift + Esc)
Go to the Details tab
Find StartMenuExperienceHost.exe
Right-click → End Task

What happens: Windows may automatically restart the process.

Fix 4: Check for Windows Updates

Sometimes Microsoft releases fixes for taskbar and Start menu issues through updates.

How to check for updates:

Open Settings → Windows Update
Click Check for updates
Install any pending updates
Restart your PC

Pro tip: If you're on an older build of Windows 11, consider updating to the latest version. Many Start menu fixes have been included in recent updates.

Fix 5: Re-register the Start Menu (Advanced)

Re-registering the Start menu can resolve certain corruption issues.

How to re-register the Start menu using PowerShell:

Open PowerShell as Administrator (search "PowerShell" in Start → right-click → Run as administrator)
Run this command:

Get-AppXPackage -Name Microsoft.Windows.StartMenuExperience | ForEach-Object { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" }

Wait for completion
Restart your PC

Important: This is an advanced fix. It may not work identically on all Windows builds. If it fails, skip to Fix 6.

Fix 6: Check for Corrupt System Files

Corrupt system files can cause the taskbar and Start menu to malfunction.

How to run SFC and DISM:

Open Command Prompt as Administrator
Run:

DISM /Online /Cleanup-Image /RestoreHealth

Wait for completion
Run:

sfc /scannow

Wait for completion
Restart your PC

Pro tip: This fixes many system-wide issues, not just taskbar problems.

Fix 7: Create a New User Account

If the taskbar works for other users but not for you, your user profile may be corrupted.

How to create a new user account:

Open Settings → Accounts → Other users
Click Add account
Follow the prompts to create a new local user account
Sign out and sign in with the new account

If the taskbar works in the new account: Transfer your files to the new account and use it as your primary account.

Fix 8: Disable Third-Party Apps and Services

Some third-party apps can interfere with the taskbar and Start menu.

How to test:

Open Task Manager → Startup tab
Disable all third-party startup apps
Restart your PC

If the taskbar works, re-enable apps one by one to find the culprit.

For services:

Press Win + R, type msconfig, press Enter
Go to the Services tab
Check Hide all Microsoft services
Click Disable all
Click Apply → OK → Restart your PC

Important: Re-enable services after testing to avoid losing important functionality.

Fix 9: Perform a System Restore (Last Resort)

If the taskbar and Start menu issues started recently, you can roll back.

How to do it:

Press Win + R, type rstrui.exe, press Enter
Select a restore point from before the problem started
Follow the on-screen instructions

Note: System Restore usually doesn't affect your personal files, but it may revert recently installed apps, drivers, and system settings.

What If You Want to Monitor Your PC Automatically?

If you're troubleshooting recurring Windows problems, it can also be useful to know what changes are happening on your PC around the same time.

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

SysPulse can:

· Detect new processes and show their full file paths
· Monitor CPU and RAM anomalies
· Detect USB connections in real-time
· Detect startup changes
· Send Telegram alerts for monitored events
· Use less than 30MB of RAM

You can set it up and let it monitor your PC in the background — so you know when something changes, even if you're not at your desk.

You can find it at: syspulse.pro

Taskbar not responding Restart Windows Explorer
Start menu won't open Re-register Start menu, restart Explorer
Taskbar missing after update Install latest Windows updates
UI issues after restart Restart Windows Explorer or your PC
System-wide UI issues Run SFC and DISM
User-specific issues Create a new user account
Third-party app interference Disable startup apps and services

Final Thought

Taskbar and Start menu problems on Windows 11 are frustrating — but they're almost always fixable.

Start with the simplest fixes:

Restart Windows Explorer
Restart your PC
Check for updates

If those don't work, move to re-registering the Start menu, SFC and DISM, or creating a new user account.

The key: Start with the simplest fixes and work your way toward deeper system repairs only if necessary.

Windows 11 Sleep Mode Not Working? Here's How to Fix Wake Issues

Darkssel — Wed, 02 Sep 2026 04:10:58 +0000

You put your PC to sleep.

You walk away.

When you come back — nothing.

The monitor stays black. The power light is on, but the system won't wake up.

Or worse — your PC keeps waking up on its own in the middle of the night.

You might think:

"Is my power supply failing? Do I need a new PC?"

Probably not.

Sleep mode problems are a common — and frustrating — issue in Windows 11. They can happen after an update, a driver change, or a misconfigured power setting.

The good news? Many sleep issues can be fixed in minutes.

This guide covers 10 practical ways to fix sleep mode problems on Windows 11 — from simple setting changes to advanced command-line fixes.

Why Is My Windows 11 PC Not Sleeping or Waking Properly?

Sleep mode problems can happen for many reasons:

Cause	Description
Power settings	Incorrect power plan configuration
Wake timers	Scheduled tasks waking your PC
Network adapters	"Wake on LAN" or other network settings
USB devices	Mice or keyboards waking your PC
Outdated drivers	Chipset, graphics, or network drivers
Fast Startup	Hybrid shutdown causing power-state issues
Windows updates	Some updates break sleep functionality
BIOS/UEFI settings	Incorrect power management settings
Background apps	Apps preventing sleep
Corrupt system files	Damaged Windows components

10 Ways to Fix Sleep Mode Problems on Windows 11

Fix 1: Check Your Power Plan Settings

The simplest fix — often overlooked.

How to check:

Search "Power Options" in the Start menu
Click Change plan settings next to your selected plan
Click Change advanced power settings
Expand Sleep → Sleep after — make sure it's set to your desired time
Expand Sleep → Allow hybrid sleep — set to Off (if you have issues)
Expand Sleep → Hibernate after — set as needed
Click Apply → OK

Pro tip: If you have "High Performance" selected, it may prevent sleep. Try "Balanced" for better power management.

Fix 2: Disable Wake Timers

Wake timers allow scheduled tasks to wake your PC. Sometimes they wake it unnecessarily.

How to disable wake timers:

Open Power Options → Change plan settings → Change advanced power settings
Expand Sleep → Allow wake timers
Set both On battery and Plugged in to Disable
Click Apply → OK

What you gain: Windows won't wake your PC for scheduled tasks (like maintenance or updates).

Fix 3: Disable Network Adapter Wake

Network adapters with "Wake on Magic Packet" or "Wake on Pattern Match" can wake your PC.

How to disable:

Open Device Manager (right-click Start → Device Manager)
Expand Network adapters
Right-click your network adapter → Properties
Go to the Power Management tab
Uncheck Allow this device to wake the computer
Also uncheck Only allow a magic packet to wake the computer (if enabled)
Click OK

Pro tip: If you use Wake-on-LAN, keep it enabled. Otherwise, disable it to prevent unwanted wake-ups.

Fix 4: Disable USB Device Wake

Mice, keyboards, and other USB devices can wake your PC. Sometimes they wake it accidentally (e.g., a slight vibration moves the mouse).

How to disable:

Open Device Manager
Expand Universal Serial Bus controllers
Right-click each device that exposes a Power Management tab → Properties
Go to the Power Management tab
Uncheck Allow this device to wake the computer
Click OK

Important: If you disable wake for your keyboard, you won't be able to wake the PC by pressing a key. Only disable for mice if you use the keyboard to wake.

Fix 5: Update Chipset and Graphics Drivers

Outdated drivers can cause sleep issues — especially chipset and graphics drivers.

How to update:

Open Device Manager
Expand System Devices (chipset drivers)
Right-click → Update driver → Search automatically for drivers
Also expand Display Adapters → update your graphics driver

For better results:

Visit your motherboard or laptop manufacturer's website
Download and install the latest chipset and graphics drivers

Pro tip: For Intel, use Intel Driver & Support Assistant. For NVIDIA, use GeForce Experience. For AMD, use Adrenalin.

Fix 6: Check Fast Startup

Fast Startup is a hybrid shutdown mode that can sometimes affect power-state transitions, including sleep and wake behavior.

How to disable (if you're experiencing issues):

Open Control Panel → Power Options
Click Choose what the power buttons do
Click Change settings that are currently unavailable
Uncheck Turn on fast startup (if available)
Click Save changes

Note: Disabling Fast Startup may slightly increase boot time, but can help with wake issues and other power-state problems. Sleep still works normally.

Fix 7: Run the Power Troubleshooter (If Available)

Windows 11 includes a built-in troubleshooter for power issues, though it may not be present on every version or build.

How to run it (if available):

Open Settings → System → Troubleshoot
Click Other troubleshooters
Look for Power → click Run
Follow the on-screen instructions

If the Power troubleshooter isn't listed, skip to the next fix.

What it does: This tool checks for common power settings issues and attempts to fix them automatically.

Fix 8: Check Event Viewer for Wake Sources

If your PC keeps waking up, you can find out exactly what woke it.

How to check:

Press Win + R, type eventvwr.msc, press Enter
Go to Windows Logs → System
Click Filter Current Log
In the Event sources dropdown, select Power-Troubleshooter
Click OK
Look for events where Wake Source is listed

Example: If Wake Source is "USB Root Hub", then a USB device woke your PC.

Pro tip: Use this command for a quick summary:


powercfg -lastwake

Fix 9: Check Background Apps Preventing Sleep

Some apps prevent your PC from sleeping — especially media players, download managers, or game launchers.

How to check:

Open Command Prompt as Administrator
Run: powercfg -requests
This shows which processes are preventing sleep

If you see a process:

Close the app that's preventing sleep
Or go to Task Manager → Processes → end the task

Common offenders:

Steam downloading updates
Chrome with background videos
Spotify
Torrent clients
OneDrive syncing

Fix 10: Reset Power Settings to Default

If everything else fails, resetting power settings to default can help.

How to reset:

Open Command Prompt as Administrator
Run:


powercfg -restoredefaultschemes

Restart your PC

Alternative: Create a new power plan:

Power Options → Create a power plan
Select Balanced
Name it Default Power Plan
Click Next → Create

What you gain: All power settings are restored to Windows defaults, which often resolves sleep issues.

What If You Want to Monitor Your PC Automatically?

Sleep issues often happen because of background processes or misconfigured settings. If you want to monitor your system for changes that could affect sleep behavior, automatic monitoring can help.

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

SysPulse can:

Detect new processes and show their full file paths
Monitor CPU and RAM anomalies
Detect USB connections in real-time
Detect startup changes
Send Telegram alerts for monitored events
Use less than 30MB of RAM

You can set it up and let it monitor your PC in the background — so you know when something changes, even if you're not at your desk.

Windows 11 KB5120998 Mouse Cursor Bug: Microsoft Confirmed the Issue — Here's How to Fix It

Darkssel — Tue, 01 Sep 2026 19:06:38 +0000

You install the latest optional update.

You restart your PC.

And then — your mouse cursor is gone.

Or it's huge. Or it's a giant white arrow that looks like it's from Windows 98.

Your wallpaper is black. Your custom cursor settings are gone.

You try to fix it. You restart again. It happens again.

You might think:

"Is my PC broken? Do I need to reinstall Windows?"

No.

On August 30, 2026, Microsoft officially confirmed that the optional update KB5120998 (released on August 27) is causing these exact issues.

The good news? This update is optional — and you can safely uninstall it.

This guide shows you exactly how to fix the KB5120998 mouse cursor and wallpaper problems — step by step.

What Microsoft Confirmed About KB5120998

Microsoft has officially acknowledged the following issues with the KB5120998 optional update:

Issue	Description
Cursor disappears	The mouse pointer is completely invisible
Cursor size changes	The cursor becomes very large or very small
Cursor resets	Custom cursor schemes revert to default
White cursor	The cursor turns into a large white pointer
Wallpaper turns black	Desktop background changes to solid black
Settings don't stick	Even if you fix them, the issues return after restart

Microsoft's official guidance: Users experiencing these issues should uninstall KB5120998. The problem is being investigated, and a permanent fix is expected in a future update.

How to Fix the KB5120998 Mouse and Wallpaper Issues

Fix 1: Uninstall KB5120998 (Recommended — The Most Reliable Fix)

Since Microsoft has confirmed the issue, uninstalling the update is the most reliable solution.

Important: KB5120998 is an optional preview update. Uninstalling it removes that optional update; it does not require reinstalling Windows.

How to uninstall from Settings:

Open Settings → Windows Update → Update history
Scroll down and click Uninstall updates
Find KB5120998 in the list
Click Uninstall
Follow the prompts and restart your PC

How to uninstall from WinRE (if your PC won't boot normally):

Boot into Windows Recovery Environment (WinRE)
Go to Troubleshoot → Advanced options → Uninstall Updates
Select Uninstall latest quality update
Follow the prompts
Restart your PC

After uninstalling: Check whether your cursor and wallpaper have returned to normal.

Fix 2: Restore Your Cursor Settings (If You Want to Keep the Update)

If you absolutely need to keep KB5120998 installed, you can try restoring your cursor settings manually. However, if the underlying update issue remains, the settings may revert after a restart.

How to restore cursor settings:

Open Settings → Personalization → Themes
Click Mouse cursor
Under Scheme, select your preferred cursor scheme
Click Apply → OK

Alternative (via Control Panel):

Open Control Panel → Mouse
Go to the Pointers tab
Select your preferred scheme from the dropdown
Click Apply → OK

Note: This is a workaround rather than a guaranteed permanent fix.

Fix 3: Restore Your Wallpaper

If your wallpaper turned black during the update, you can change it back.

How to change your wallpaper:

Right-click on the desktop → Personalize
Click Background
Select a new background image or color
Click Apply

Note: If the update is still installed, the wallpaper problem may return.

Fix 4: Pause Windows Updates Temporarily

After uninstalling the update, you can temporarily pause Windows Update while waiting for Microsoft's next update or a confirmed fix.

How to pause updates:

Open Settings → Windows Update
Click Pause updates
Select the available pause period

Note: Pause updates only temporarily. Windows will resume updates automatically after the selected period.

What NOT to Do

Don't reinstall Windows — this issue is associated with the optional update.
Don't change random registry settings — there's no need for registry modifications as a first-line fix.
Don't repeatedly reset your cursor settings — if the update is causing the problem, the settings may revert.
Don't panic — removing the problematic optional update is much simpler than reinstalling the entire operating system.

Windows 11 Very Slow After 2026 Updates? Here's How to Fix Performance Issues

Darkssel — Tue, 01 Sep 2026 16:16:54 +0000

You install the latest Windows update.

You restart your PC.

And then — everything is slow.

Apps take forever to open. File Explorer lags. The fan is loud. RAM usage is through the roof.

You might think:

"Is my PC too old for Windows 11? Do I need to upgrade my hardware?"

Probably not.

Some Windows 11 updates released in 2026 have been associated with performance issues for some users. For example, the June 2026 cumulative update (KB5094126) has been linked to system freezes, severe lag, and high CPU usage, as reported by multiple users on Microsoft's official Q&A forums and other platforms[reference:0][reference:1].

The good news? Many performance problems after updates can be fixed without reinstalling Windows.

This guide covers 11 practical ways to fix slow performance on Windows 11 after updates — from simple tweaks to advanced repairs.

Why Is Windows 11 So Slow After 2026 Updates?

Several factors can cause slowdowns after updates:

Cause	Description
Background scanning	Windows Defender or other security tools running full scans
Driver conflicts	Updated drivers not fully compatible with your hardware
Increased resource usage	New features or services consuming more CPU, RAM, or disk
Corrupt system files	Update installation left some files damaged
Startup overload	More apps added to startup automatically
Power plan changes	Updates may reset your power plan to a less performance-friendly setting
Memory management changes	Page file or memory compression settings altered

11 Ways to Fix Slow Performance After Updates

Fix 1: Check Task Manager for Resource Hogs

The first step is to identify what's consuming your system resources.

How to check:

Press Ctrl + Shift + Esc to open Task Manager
Go to the Processes tab
Sort by CPU, Memory, or Disk usage
Look for any process that's using unusually high resources

Common culprits after updates:

Antimalware Service Executable — Windows Defender scanning
Service Host: SysMain — SuperFetch preloading
Windows Update running in the background
Third-party antivirus scanning

What to do:

If it's a temporary process (like a scan), wait for it to finish
If it's a known app (like a browser), close it
If it's a system process and it's constantly high, continue with the fixes below

Fix 2: Disable Unnecessary Startup Apps

Some updates can add new apps to startup without your permission.

How to disable startup apps:

Open Task Manager (Ctrl + Shift + Esc)
Go to the Startup tab
Sort by Startup Impact
Right-click and Disable anything you don't need immediately

Common offenders:

Spotify
Discord
Adobe Creative Cloud
Game launchers (Steam, Epic, etc.)
Zoom / Teams

Pro tip: You can always open these apps manually when you need them.

Fix 3: Turn Off Visual Effects

Windows animations and transparency effects can slow down your system — especially after updates.

How to disable visual effects:

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
Click Apply → OK

What you gain: A snappier, more responsive PC.

Fix 4: Change Power Plan to High Performance (With Caution)

Sometimes updates reset your power plan to Balanced or Power Saver.

How to check and change:

Search Power Options in the Start menu
Select High Performance (if available)
If you don't see it, click Show additional plans
If still not available, create a new plan:
- Click Create a power plan
- Select High Performance
- Name it Gaming Performance or High Performance
- Click Next → Create

Note: On laptops, this may reduce battery life and increase heat — use only when plugged in and if you are comfortable with the trade-offs.

Fix 5: Run Disk Cleanup (Including System Files)

Updates often leave behind old files that take up space and slow down your system.

How to run Disk Cleanup:

Press Win + R, type cleanmgr.exe, press Enter
Select your C: drive → Click OK
Click Clean up system files
Select C: again → Wait for the scan
Check:
- Windows Update Cleanup
- Temporary files
- Previous Windows installations (if present)
- Delivery Optimization Files
Click OK → Delete Files

What you gain: Freed space that can help improve performance.

Fix 6: Disable Windows Search Indexing (If on HDD)

Windows Search indexes your files to make searches faster. On HDDs, this can cause significant slowdowns.

How to disable it (optional):

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

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

Note: This is most effective on HDDs. On SSDs, the impact is usually small.

Fix 7: Disable SysMain (SuperFetch) — Optional

SysMain preloads apps to speed up startup. On older systems, it can cause disk usage spikes.

How to disable it:

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

Note: This is an optional tweak. It may slightly increase app loading times but can significantly reduce disk usage on older systems — especially those with HDDs and high disk usage.

Fix 8: Update Drivers (Especially Chipset and Graphics)

Outdated or incompatible drivers can cause performance problems after updates.

How to update drivers:

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

For better results:

Visit your motherboard or laptop manufacturer's website
Download and install the latest Chipset drivers, Graphics drivers, and Storage controller drivers

Pro tip: For NVIDIA, AMD, or Intel graphics, use their official tools (GeForce Experience, Adrenalin, or Intel Driver & Support Assistant) for automatic updates.

Fix 9: Run SFC and DISM

Corrupted system files from a bad update can cause slowdowns.

How to run SFC and DISM:

Open Command Prompt as Administrator
Run:


DISM /Online /Cleanup-Image /RestoreHealth

Wait for completion (10–15 minutes)
Run:


sfc /scannow

Wait for completion
Restart your PC

Pro tip: This fixes many system-wide issues, not just performance problems.

Fix 10: Adjust Page File (Virtual Memory)

Windows uses a page file as virtual memory when RAM is full. A poorly sized page file can cause performance issues.

How to check and adjust:

Press Win + R, type sysdm.cpl, press Enter
Go to the Advanced tab
Under Performance, click Settings
Go to the Advanced tab
Under Virtual memory, click Change
Make sure Automatically manage paging file size for all drives is checked — this is the safest option for most users

Only change this if: You're running low on disk space and know what you're doing. Avoid disabling it entirely.

Fix 11: Change File Explorer to Open "This PC" (Optional)

By default, Windows 11 File Explorer opens to the Home page, which loads recent files and cloud content. This can slow down File Explorer.

How to change it:

Open File Explorer
Click the View menu → Options → Change folder and search options
Under the General tab, change Open File Explorer to: from "Home" to "This PC"
Click Apply → OK

Windows 11 Audio Not Working? Here's How to Fix Sound Problems

Darkssel — Tue, 01 Sep 2026 16:04:09 +0000

You open a video.

You press play.

The video runs — but there's no sound.

You check the volume. It's not muted.

You restart your PC. Still nothing.

You might think:

"Is my sound card broken? Do I need a new PC?"

Probably not.

Audio problems are one of the most common issues in Windows 11. They can happen after a Windows update, a driver conflict, a wrong setting, or just randomly.

The good news? Many audio issues can be resolved in minutes.

This guide covers 9 practical ways to fix sound problems on Windows 11 — from simple checks to driver updates.

Why Is My Audio Not Working on Windows 11?

Audio problems can happen for many reasons:

Cause	Description
Wrong output device	Windows is sending sound to the wrong speaker or headphone
Muted or low volume	Sound is muted in Windows or on the device itself
Outdated or corrupted driver	Audio driver needs updating or reinstalling
Windows updates	Some updates break audio drivers
Disabled audio services	Windows Audio service is stopped
App-specific issues	One app has no sound while others work
Hardware problems	Loose cable, faulty speaker, or headphone jack
Audio enhancements	Windows audio enhancements causing conflicts

9 Ways to Fix Audio Problems on Windows 11

Fix 1: Check the Physical Connections

Before you change any settings, check the basics:

Is your speaker or headphone plugged in properly?
Is the power cable connected (if using powered speakers)?
Is the volume dial on your speaker turned up?
Are Bluetooth headphones paired and connected?

Pro tip: Try plugging your headphones into a different device (like your phone) to verify they work.

Fix 2: Run the Audio Troubleshooter

Windows 11 has a built-in troubleshooter for audio problems.

How to run it:

Open Settings → System → Sound
Scroll down and click Troubleshoot common sound problems
Follow the on-screen instructions

Alternative: Open Settings → System → Troubleshoot → Other troubleshooters → Audio → Run

What it does: This tool checks for common audio issues — like disabled services, driver problems, or wrong output devices — and attempts to fix them automatically.

Note: The exact path to the troubleshooter may vary slightly depending on your Windows 11 version and updates.

Pro tip: Run this before trying more advanced fixes.

Fix 3: Check Your Output Device

Sometimes Windows switches to the wrong output device — like sending sound to your monitor instead of your headphones.

How to check:

Open Settings → System → Sound
Under Output, make sure the correct device is selected
If you see multiple options, try switching to another one

Alternative: Click the sound icon in the taskbar → click the arrow next to the volume slider → select the correct output device.

Pro tip: If the correct device isn't listed, skip to Fix 5.

Fix 4: Check Volume Levels and Mute Settings

Sometimes sound is muted — but it's not obvious.

How to check:

Click the sound icon in the taskbar
Make sure the master volume is not muted and is turned up
Click the sound icon → Volume mixer (or right-click → Open Volume mixer)
Check that your app's volume is not muted or set too low

Also check: If you're using headphones or speakers with a physical volume dial, make sure it's turned up.

Fix 5: Restart the Windows Audio Service

The Windows Audio service manages all sound on your PC. If it's stopped or stuck, sound won't work.

How to restart it:

Press Win + R, type services.msc, press Enter
Find Windows Audio
Right-click → Restart

If the service is stopped:

Right-click → Start
If the service fails to start automatically, consider changing Startup type to Automatic — but only after checking that the service isn't disabled intentionally.

Pro tip: Also check Windows Audio Endpoint Builder — restart it as well.

Fix 6: Update or Reinstall Your Audio Driver

A corrupted or outdated audio driver is one of the most common causes of audio issues.

Before you start: If possible, download the latest audio driver from your PC or motherboard manufacturer's website before uninstalling the current driver.

How to update the driver:

Open Device Manager (right-click Start → Device Manager)
Expand Sound, video and game controllers
Right-click your audio device → Update driver → Search automatically for drivers

If that doesn't work, reinstall the driver:

Right-click your audio device → Uninstall device
If Windows shows the option, check Delete the driver software for this device
Click Uninstall
Restart your PC
Windows will attempt to reinstall the driver automatically

If Windows doesn't reinstall the driver: Install the driver you downloaded earlier from the manufacturer's website.

Common audio drivers/devices:

Realtek (most common on motherboards)
Intel (common on laptops)
NVIDIA (HDMI audio)
AMD (HDMI audio)

Fix 7: Disable Audio Enhancements

Windows audio enhancements can sometimes cause conflicts or poor sound quality.

How to disable them:

Open Settings → System → Sound
Click your output device → Properties (or Device properties)
Under Enhancements (or Effects):
- Toggle Enhance audio to Off
- Or uncheck Enable audio enhancements

Alternative (via Control Panel):

Open Control Panel → Sound
Right-click your output device → Properties
Go to the Enhancements tab
Check Disable all enhancements
Click Apply → OK

Fix 8: Check App-Specific Audio Settings

Sometimes one app has no sound while others work fine.

How to check:

Click the sound icon in the taskbar → Volume mixer
Check if the specific app is muted or set to a very low volume
Adjust its volume

For individual apps:

Check the app's own volume settings
Some apps (like browsers) have their own mute buttons
Make sure the app isn't muted in Windows Sound settings

Fix 9: Perform a System Restore (Last Resort)

If audio stopped working recently and nothing else helps, you can roll back.

How to do it:

Press Win + R, type rstrui.exe, press Enter
Select a restore point from before the problem started
Follow the on-screen instructions

Note: System Restore doesn't affect your personal files — only system settings and installed programs.

Summary Table

Problem	Quick Fix
No sound at all	Check physical connections, run Audio Troubleshooter
Wrong output device	Change output device in Sound settings
App has no sound while others work	Check Volume Mixer for that app
Audio driver issue	Update or reinstall audio driver
Audio service stopped	Restart Windows Audio service
Audio enhancements causing issues	Disable audio enhancements
Sound stopped after Windows update	Roll back or reinstall audio driver
Hardware issues	Test speakers/headphones on another device
