Windows Vista was Microsoft's successor to Windows XP, and Beta 2 arrived in 2006 as a widely tested pre-release build before the final system launched in early 2007. Its startup sound reflects the Aero era design, with glassy visuals and softer interface sounds replacing the look and feel of XP. Clips from beta builds later circulated among Windows enthusiasts and collectors who compare unreleased sounds with retail versions. That collector interest keeps this short chime in use for retro computing videos, operating system histories, and memes about old PCs starting up slowly today.
