Windows Vista was Microsoft's successor to Windows XP, released in 2007, and its system sounds were designed to feel softer and more welcoming than earlier versions. The log off chime played when a user signed out, marking a quiet end to a session. After Vista was replaced by Windows 7 in 2009, the sound survived mainly through nostalgia, appearing in retro computer videos, tech memes, and soundboard collections. It remains recognisable because so many people heard it daily on home and school computers during the late 2000s.
