Windows Vista was released by Microsoft in 2007, and its logo animation used a short, polished musical signature designed to sound modern, calm and welcoming for a new generation of computers. As Vista machines became common in homes and offices, the sound became closely associated with booting up, installing software and first opening a new PC. Years later, clips of it began circulating online in nostalgia videos, retro tech retrospectives and parodies of old operating systems. It remains popular because it instantly signals the mid-2000s era of computing, even for viewers who never used Vista themselves.
