The Fake Update Screen imitates an operating-system update that is stuck “installing” — a spinner, a reassuring message and a percentage that creeps up, plateaus and never quite finishes. It is the classic harmless desk prank: leave it fullscreen on a friend’s monitor and watch them wait.
What you can do with it
- A harmless desk prank — leave it running before a coffee break
- A believable “please wait” filler for videos and sketches
- A fake “updating” holding screen for bits and streams
How to use System Update
Open Customize to set the colours, title and behaviour, then press Fullscreen (or add ?present=1 to the URL) for a clean, controls-free screen. To run it unattended on a stream, copy the OBS browser-source URL; to drop it into a web page, use the <iframe> embed. Everything is a visual prop — no real hacking, network or data.
Will it actually update or install anything?
No. Nothing installs, downloads or changes. It is a full-screen picture of an update with an animated percentage — pure fiction.
How do I exit the prank?
Press Escape (or leave fullscreen). No settings are changed and nothing needs undoing.
