Windows ME, short for Windows Millennium Edition, was released by Microsoft in 2000 as a home-focused successor in the Windows 9x family. Its startup sound greeted users when the system booted, becoming a small but recognisable part of the experience of using a turn-of-the-century PC. As retro computing videos, nostalgia edits and memes about aging technology grew online, the short jingle was reused as audio shorthand for that era. It remains popular because it instantly places a scene in the early 2000s without needing any explanation.
