Windows Vista build 5000 (vbl_core.040808-2000) is a build of Windows Vista. On 23 January 2020, 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 his 33 Longhorn/Vista builds on 26 January 2020, alongside build 4048, other compiles of this build, and build 5001. This build by default has a severe bug where it appears to hang as soon as Windows switches to graphical mode, ending up with a solid blue or black screen, making this build not installable under normal conditions.
