The Windows XP startup sound comes from Microsoft's Windows XP operating system, released in 2001. It became one of the most recognizable computer boot sounds of the early 2000s because millions of people heard it at home, school and work. Long after XP faded out, the chime kept circulating in memes, nostalgia compilations and retro tech videos. It is still used as a quick shorthand for old PCs, internet throwbacks and classic desktop culture, often alongside Windows XP error music in edits about vintage computing.
