Fake Windows update FAQ
How do I make a fake Windows update screen?
Press Start prank on this page. The fake update screen opens in full screen with a slowly rising percentage. Choose the length first, from 1 minute to 2 hours.
How do I exit the fake update screen?
Press Esc. Leaving full screen also ends it, and a small “Esc to exit” button sits in the bottom corner.
Does it change anything on the computer?
No. It is just a web page in full screen. Nothing is installed or changed, and closing the tab ends it too.
What happens when it reaches 100%?
It shows “Finishing up”, a short restart animation and then a lock screen with the time, which stays until you press Esc.
