This clip is a user-made mashup rather than an official Microsoft sound, pairing the recognisable Windows 3.1 startup chime with a slow fart for comic effect. It circulates on soundboards as a short fart meme sound that creators reuse whenever they want retro technology to turn suddenly crude and silly. Its appeal comes from that simple twist: the familiar boot-up cue sets up a serious, nostalgic expectation, then the drawn-out noise breaks it. Because the joke is instantly understood without any context, it keeps appearing in prank videos, edits and reaction clips.
