Windows XP launched in 2001 and became one of the most widely used desktop operating systems of its era, so its startup and shutdown chimes were heard daily by millions of people at home, school, and work. When support ended in 2014 and newer systems replaced it, those notes turned into instant nostalgia. Clips and remixes spread on video and soundboard sites, and the shutdown chime kept its role as an exit cue, much like the Disconnect discord sound for leaving a voice chat.
