Microsoft released Windows 2000 for business users in early 2000 after preview builds circulated in 1999, and Windows ME arrived later that same year for home users with the identical startup chime. As those systems aged, the sound survived on nostalgia channels, retro computing forums and meme edits, often paired with a computer error sound for comic effect. Creators still reach for it when they need an instantly recognisable old PC moment, because few other clips mark outdated technology, patience and early internet culture quite so quickly in a few seconds.
