Windows 2000 was released by Microsoft in 2000 as a business-focused successor to Windows NT 4.0, and its default system sounds, including the shutdown chime, were part of the everyday experience of using a PC at the time. As later versions of Windows replaced these sounds, the closing jingle became a shorthand for early 2000s computing. It now circulates online as a short nostalgic clip, recognised by former users and reused in retro technology videos, old computer restorations and edits about logging off for good.
