About this tool
A full-screen overlay styled after the classic "installing updates, do not turn off your PC" screen, with a spinning loader and a percentage that moves in tiny, irregular increments — by design it takes an implausibly long time to go anywhere. Nothing is actually installing; any keypress, click, or tap exits immediately.
Good for the classic "leave it running on a coworker's monitor before a meeting" prank, or a screen-share gag while you pretend to troubleshoot.
Questions about the fake update screen
Does it install anything?
No. Nothing is installed or changed; it’s just a full-screen page.
Which speed is funniest?
Painfully slow is the classic. Stuck at one number is good for a quick reaction.
How do I exit it?
Press any key, click or tap.
Can I use it on a video call?
Yes. Share the screen and pretend you’re stuck waiting for an update.
