It is built purely for harmless pranks and jokes: trick a coworker or family member into thinking your laptop is mid-update so they leave it alone, fake being "busy" installing updates when someone asks you to do something at your desk, or just get a laugh by launching it right when someone walks by. Nothing on your actual computer changes, it is only a fullscreen visual playing in your browser tab, and pressing Escape exits it immediately.

Bill Gates co-founded Microsoft in 1975 and was deeply involved in Windows' early development and public launches, most famously presenting Windows 95 himself and dancing on stage to the Rolling Stones' "Start Me Up" at its launch event. He stepped back from Microsoft's day-to-day product decisions once Steve Ballmer took over as CEO in 2000, though he stayed on as chairman and an influential voice at the company for years afterward.

The full-screen "Working on updates, don't turn off your PC" screen this tool imitates dates back to Windows Vista and became a defining feature of Windows 7, 8, and 10, replacing the older habit of quietly installing patches in the background without telling you. Microsoft added the spinning dots and percentage counter specifically so people would not panic and force a shutdown mid-installation, since interrupting some updates could corrupt the system.

It is hard to pick just one, since this same generic blue loading screen has embarrassingly shown up live on giant venue screens, television broadcasts, retail displays, and public information boards more times than anyone has bothered to count. The reason is almost always the same, and part of what makes it funny: whatever system quietly runs that public display in the background is just a Windows PC, and it wanted to install its updates at the worst possible moment.
