Microsoft commissioned Brian Eno in 1995 to compose a startup sound for Windows 95 that felt inspiring, futuristic and optimistic. Eno, a pioneer of ambient music, submitted dozens of short options, and the selected piece became the default welcome heard as the system loaded. The sound continued to be associated with later releases including Windows 98 and Windows 2000, embedding it in the memory of a generation of PC users. It later circulated widely in retro computing videos, memes and remixes celebrating 1990s technology.
