Windows Vista was Microsoft's successor to Windows XP, released to consumers in early 2007, and its startup chord was part of a new set of system sounds designed to feel warmer and less intrusive than earlier versions. As Vista faded and Windows 7 and 10 took over, the short chime lived on in YouTube nostalgia videos, tech retrospectives and meme edits that used it as instant shorthand for the mid-2000s PC era. Today it survives mainly as that cultural cue, instantly recognisable even to viewers who never used Vista itself.
