The Windows startup chime is the short sound Microsoft computers play when the operating system finishes loading, and it has become one of the most instantly recognisable computer sounds in everyday life. Online creators later took that familiar jingle and pushed its volume far beyond normal, creating loud, distorted versions that spread through meme soundboards and short-form videos. The humour comes from recognition and excess: everyone knows the polite original, so the amplified version feels deliberately absurd. That contrast is why the clip still appears in pranks, reaction edits and gaming content.
