The name points to the Windows family of operating systems, whose numbered releases shaped personal computing in the 1990s, and the shutdown chime became a familiar end-of-session cue for desktop users. As old computers were replaced, clips of their startup and shutdown sounds survived on video sites and soundboards, where creators reuse them as shorthand for an era of bulky monitors, floppy disks and dial-up connections. It remains popular because the sound is instantly recognisable, even to people who never used that exact version, and it signals a clean ending.
