Windows 2000 was released by Microsoft in 2000 as a business-focused successor to Windows NT 4.0, and its system sounds, including the shutdown chime, were part of the everyday experience for office and home users in the early 2000s. As newer versions of Windows replaced it, the sound survived through retro computing videos, nostalgia compilations and meme edits that reused old operating system audio. It is still used today because it is instantly recognisable to anyone who used a PC at the time, and its gentle ending makes it a useful shorthand for closure in short-form video.
