Windows 2000 and Windows Me were both Microsoft operating systems released in 2000, and each shipped with its own set of system sounds for starting up, logging off and shutting down. The logoff and shutdown chime captured here comes from that era of desktop computing, when closing a PC was a distinct, audible event rather than a silent sleep. Today the clip circulates on soundboards and in retro computing videos, where its brief, dated tone instantly places a scene in the early 2000s and gives creators a quick, recognisable way to signal that a computer, session or joke has ended.
