Windows XP launched in 2001 and became one of Microsoft's most widely used operating systems, so its default sounds were heard in homes, schools and offices for over a decade. The shutdown chime closed every session, pairing with the green Start button and rolling hills wallpaper in most people's memory. After support ended in 2014 the sound survived online as a nostalgia cue, reused in retro computing videos, fake error edits and memes about something powering down for good.
