Windows Vista build 5000 (vbl_core.040809-2000) 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 is not much different from the other compiles, aside from having the "Access Violation" problem in the win32k.sys file from the earlier day's compile fixed.
