FAQ

Will this actually update my system?

Not at all. This is just a visual simulation running in your browser — it performs no actual system updates. Click anywhere to safely exit.

Can I use it to prank friends?

Absolutely! Go full-screen and walk away, making your friends think the computer is updating. The Windows version is especially convincing with the Microsoft blue theme and progress bar.

How long does the simulation take?

About 30 seconds, using a non-linear progress bar (fast at start and end, slower in the middle) to mimic real update pacing. You can click to exit at any time.
