Windows Vista was released by Microsoft in 2007, and its startup sound quickly became one of the most recognisable audio signatures of that era. Designed to feel calm and welcoming, the short melody replaced the louder, more dramatic startup sounds of earlier Windows versions. As Vista machines disappeared, the chime survived online through nostalgia videos, parodies and anniversary tributes, where it now works as instant shorthand for mid-2000s computing. Its gentle tone is why it still feels familiar even to people who never owned a Vista computer.
