Microsoft released Windows Vista in 2007, and its short startup sound quickly became one of the most recognisable sounds of the mid-2000s personal computer era. It was heard by millions of users as their computers loaded, and its calm, polished tone stood out from the sharper system sounds that came before it. As older computers disappeared, the clip survived online through nostalgia videos, retro computing channels and meme edits, where it now signals an old PC, a bygone version of the internet or a deliberately dated piece of technology.
