The sound originated as the default startup chime for Microsoft Windows XP, the operating system released in 2001 that defined a generation of home computers. Its gentle, optimistic melody became instantly familiar from offices, schools and bedrooms. Online, creators began boosting familiar system sounds far beyond normal levels for earrape humour, and this 300 percent version circulated on soundboards alongside the Windows error sound in retro PC meme edits. It remains popular because the contrast between a calm, nostalgic boot up and painful loudness is immediately funny to anyone who grew up hearing it daily.
