I built a Windows lock app that kills Task Manager. Here's how.

Most Windows lock apps are a joke.

Alt+Tab your way out. Open Task Manager. Kill the process. Done. Bypassed in 3 seconds.

I got tired of this. So at 13, I built ATLOCK.

Here's exactly how the hardening works:

1. Low-Level Keyboard Hook

Windows has a hook called WH_KEYBOARD_LL — it intercepts keystrokes at the OS level before any app can process them.

ATLOCK uses this to block:

Alt+Tab
Win key
Alt+F4
Escape

No app can bypass this. Not even Task Manager.

2. Task Manager Watchdog

A background thread runs continuously — checking every 500ms if Task Manager (taskmgr.exe), Process Hacker, or ProcExp is running.

If detected — killed instantly.

The user never even sees it open.

3. Focus Enforcement Loop

Another thread constantly calls focus_force() and grab_set() — making sure the lock screen always stays on top.

Even if something tries to push it to background — it snaps back immediately.

4. The Result

A lock screen that genuinely cannot be escaped conventionally.

No Alt+Tab. No Task Manager. No background push. Timer runs out or correct password — those are your only two options.

Why I Built This

I'm Akhouri Anmol Kumar — 13 years old, India, founder of Akhouri Systems.

ATLOCK also has File Guard (NTFS ACL-level), Password Vault with 10-hour lockout, and a Notification Panel.

Single .exe. No installation. Just run.

Feedback welcome — especially from security researchers.

I'm Akhouri Anmol Kumar — a 13-year-old software developer from Jharkhand, India, and the founder of Akhouri Systems.

I started building software because I was frustrated. Every app I used had problems nobody bothered to fix. Windows Notepad hadn't changed in decades. Lock apps could be bypassed in 3 seconds. Calculators had zero personality.

So I built my own.

In the last few months, I shipped 4 Windows desktop applications completely solo:

ATLOCK — A total security suite. System lockdown, file guard, password vault, and security hardening. Once locked, there is no escape. Alt+Tab blocked. Task Manager killed on sight.

ANOTE — A premium text editor. Multi-tab, syntax highlighting, password lock, translator, meme canvas. Everything Notepad should have been.

ACALCU — The world's most customizable calculator. Right-click any button. Change colors, fonts, even set videos as button backgrounds.

APIC — Advanced Image Processing Center. Edit, convert, compress, batch process — all in one app.

Every single line of code written by me. No team. No funding. No mentor.

I named the company Akhouri Systems because I wanted it to feel like a real company — because it is one.

We build what others forgot to fix.

This is just the beginning.
