The Windows Vista boot chime has been officially retired from Windows 11. A bug caused the Vista sound to play during the startup of Windows 11, which Microsoft acknowledged in June and confirmed it was a bug, not an intentional feature. The issue was resolved in Windows 11 Build 27913, which stated that the unexpected use of the Vista boot sound was fixed. Microsoft first introduced startup sounds with Windows 3.1, and they were omitted in Windows 8, but a startup sound was reinstated for Windows 11.
