Windows XP launched in 2001 as Microsoft's mainstream operating system and its system sounds became part of everyday computing for a generation. The logoff chime was heard alongside the startup melody and the familiar error sound, embedding it in school, home and office routines. As XP was retired, the sounds survived online in memes, remixes and retro videos. Creators now use the logoff clip out of context to signal that someone is done, leaving or mentally shutting down, long after the operating system itself faded from daily use.
