I am 13. I reverse-engineered why every Windows lock app fails. Then I fixed it.

Most Windows lock apps fail the same way. Open Task Manager. Kill the process. Done. Bypassed. I spent weeks understanding exactly why. The answer: they block at application level. Not OS level. So I went deeper. WH

Most Windows lock apps fail the same way.

Open Task Manager.
Kill the process.
Done. Bypassed.

I spent weeks understanding exactly why.

The answer: they block at application level.
Not OS level.

So I went deeper.

WH_KEYBOARD_LL hook — OS level keyboard intercept.
Watchdog thread — kills Task Manager in milliseconds.
Focus enforcement loop — lock screen unmovable.
NTFS ACL — files untouchable by anyone.

The result: ATLOCK.

A lock screen with two exits only.
Correct password. Or timer end.

Nothing else works.
