How to use it
- Pick a style. Blue, Dark and Light look like a computer update, Phone looks like a phone installing an update, Retro looks like an old text mode upgrade.
- Pick how long it takes to reach 100%. The percentage moves unevenly, with quick bursts and long pauses, just like a real update.
- Tick Get stuck at 99% forever for maximum suffering, or choose what happens at 100%: start the next update, show a restart, or show your own message.
- Press Start the fake update, or press F. Press Esc to exit.
Setting it up on a friend's computer
- Open this page on their computer while they are away, press Start the fake update and leave. The mouse pointer hides by itself after a couple of seconds.
- Clicking and typing do nothing, so it looks like the computer is locked in an update.
- For a phone or tablet, use the Phone style and add the page to the Home Screen first on iPhone so the browser bar does not show.
- Tell them before they switch it off at the wall. A real update being cut off can cause trouble, so the joke should end before anyone reaches for the power button.
Other uses
- Buy yourself a break. A fake loading screen on a work monitor says "I cannot do anything right now" better than any excuse.
- Videos and slides. A clean loading screen for a film scene, a presentation joke or a stream intermission.
- Screen time. Put it on the kids' tablet at bedtime and explain that the update will take all night.
Questions
Is this a real update?
No. It is a web page that shows a spinner and a counting percentage. Nothing is downloaded or installed and the device is not changed in any way.
How do I get out of the fake update screen?
Press Esc. On a touch screen, tap once and a small Esc button shows in the top right corner, or swipe back or close the tab.
Why do clicks not close it?
So the prank does not end the moment someone touches the mouse. Only Esc, the small exit button or closing the tab ends it.
Can I make it get stuck at 99%?
Yes. Tick Get stuck at 99% forever. The percentage climbs as usual, then stops at 99% and never moves again.
Does it look like a real operating system?
It is inspired by update screens in general but uses its own layout and wording, with no logos from any real company.
