The Windows 95 startup sound originated with Microsoft's Windows 95 release in 1995. The short chime was composed by Brian Eno and became one of the most recognizable computer sounds of the 1990s. It spread far beyond the operating system through tech nostalgia videos, remix culture, and memes about old PCs and the early internet. It still gets used because a few seconds of audio instantly suggest booting up, digital optimism, and a very specific era of home computing, much like the Windows XP shutdown sound does for later PCs.
