Microsoft released Windows XP in October 2001, and the startup chime became one of the most heard sounds of that decade as the system spread to homes, schools, and offices worldwide. It was paired in everyday memory with the Windows XP error music and the Bliss wallpaper, forming a complete sound picture of early 2000s computing. As XP was retired in 2014, the clip survived online through soundboards, meme edits, and nostalgia compilations, where a few seconds are enough to identify the era instantly.
