Windows 2000, released by Microsoft in 2000, used a short, polite shutdown chime to signal the end of a session, and that sound became a familiar marker of early 2000s computing. Years later, creators began slowing, pitch-shifting and clipping those classic system sounds to make them feel haunted or broken, a style that spread through meme edits and soundboards. This distorted version keeps that nostalgia while flipping it into something eerie, which is why it still appears in retro tech jokes, vaporwave edits and ironic crash compilations.
