What It Does: Makes it look like Windows is updating forever.

How to Use It:

1. Open the file on their laptop when they step away (bathroom break, lunch, you know the drill).
2. Set the duration. If you’re wicked, go for 5 minutes. If you’re Satan, try 10.
3. Click “Enable fullscreen mode” (this is key, no escape route visible).
4. Hit “Start Prank” and walk away like nothing happened.
5. Watch from a safe distance as they return to “Working on updates… 3% complete.”
