Windows Longhorn was the codename for the operating system that eventually became Windows Vista, and during its long development after Windows XP, enthusiasts shared imagined concepts for its look and sound online. This clip is one of those fan-made fakes from 2003, created in the style of the XP startup rather than by Microsoft itself. It has survived in soundboard collections because it captures a specific what-if moment in Windows history, and creators still reuse it for retro computing jokes, fake OS videos and nostalgia edits about early-2000s PCs.
About this sound
A fake 2003 Windows Longhorn startup sound, styled like an early Windows XP boot chime. Creators use it for retro tech jokes and parody operating system intros.
This short clip imagines what Windows Longhorn might have sounded like when it booted up in 2003, long before it became Windows Vista. It opens with a soft, polished chime that builds into a smooth, hopeful melody, closely echoing the familiar Windows XP startup style but with a slightly more futuristic sheen. The tone feels clean, optimistic and unmistakably early-2000s, which makes it instantly recognisable to anyone who grew up hearing a PC switch on. Played over a video, it creates a wave of tech nostalgia and a playful sense that something new is about to begin.
