Windows XP was Microsoft's operating system released in 2001, and its startup sound played as the system loaded, becoming one of the most recognised sounds from early desktop computing. As XP machines became common in homes, schools and offices, the chime became tied to memories of family computers, early internet use and first experiences with games and messaging. Years after support ended, clips of the sound spread through memes, reaction videos and retro edits, where it now works as instant shorthand for the 2000s and for a simpler, slower era of technology.
