Windows Vista launched in 2007 with a redesigned set of system sounds intended to sound calmer and less intrusive than Windows XP. Its shutdown chime was part of that scheme and was carried over to Windows 7, which is why many listeners know it from both systems. As those versions aged, the clip resurfaced in nostalgia posts, fake error videos and meme edits online, where the instantly recognisable power down cue now signals an ending, a freeze or someone mentally switching off.
