Microsoft introduced this startup sound with Windows Vista in 2007, replacing the simpler tones used by earlier versions of the operating system. The same chord, or close variants of it, continued to be associated with Windows 7, Windows 8, and later releases, which is why many listeners recognise it across several generations of PCs. Clips of the sound later spread on soundboards and in short videos, where editors reuse it as shorthand for booting up, logging in, or returning to an old computer.
