Windows XP launched in 2001 and became one of the most widely used PC operating systems of its era, making its default startup and shutdown chimes instantly familiar to millions. The shutdown melody was heard daily in homes, offices and schools, so it remained embedded in popular memory long after support ended in 2014. As retro tech nostalgia grew on video platforms, creators reused the chime alongside the classic error sound in edits and memes. Its calm finality still works as a universal cue that something is closing, logging off or powering down for good.
