The Windows XP shutdown sound comes from Microsoft Windows XP, released in 2001, and became widely recognizable because of how common the operating system was on home and school computers. Over time, people began reusing its shutdown chime in memes, compilations, and nostalgic edits to represent an ending, a mental crash, or a system powering off. It is still popular because even a very short clip can instantly evoke early PC culture. It is often paired with the Windows XP Error sound in retro tech jokes.
