About this prank
This is the classic office prank: the screen someone comes back to and cannot do anything about. It fills the display with the “Working on updates” message, the spinning ring of dots and a percentage that climbs in uneven steps and then stalls in the nineties — the detail that makes people give up and walk away rather than wait.
Nothing is installed, downloaded or changed. It is a web page drawing a picture of an update screen, and pressing Esc ends it instantly. Because it is only a page, it works on any computer, including a Mac.
If you want the crash rather than the update, try the fake blue screen of death, the fake error message generator or hacker typer.
