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.
