Microsoft introduced this sound with Windows XP in 2001, replacing the shorter chimes of earlier versions with a warmer, more orchestral welcome. It played automatically on millions of home and office PCs for over a decade, making it one of the most recognised computer sounds in the world. As XP faded, the clip lived on through online compilations, nostalgia channels and meme edits, where its familiar swell instantly signals the early 2000s. Today creators still use it as shorthand for retro computing and simpler technology.
