This sound was the startup jingle for Windows NT 4.0, Microsoft's business-focused operating system, and it also appeared in early builds of NT 5.0, which later became Windows 2000. Unlike the more familiar consumer Windows chimes, it was associated with workstations and office machines, giving it a distinct place in computing history. It has since circulated on soundboards and in retro technology videos, where creators reuse it as an instantly recognisable cue for old computers, vintage software and the early days of modern desktop computing.
