Windows Vista build 5000 (vbl core.040808-2000)

Windows Longhorn build 5000 (vbl core) (with a buildtag of 5000.vbl_core.040808-2000) is a build of Windows Vista. On 2020-01-23, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to the BetaArchive FTP, and was released in the third set of 33 other Longhorn builds on 2020-01-26, alongside build 4048, other compiles of this build, and build 5001.

This build has a severe bug where it appears to hang as soon as Windows switches to graphical mode, ending up with a light blue or black screen, and making this build technically uninstallable.
