Windows Vista build 5000 (vbl core.040803-2000)

Windows Vista build 5000 (vbl core.040803-2000) is a build of Windows Vista. Prior to its leak, there were some alleged screenshots of this build circulating on the internet, but they are fake due to containing the Bliss wallpaper with a bull, which is not included on the actual build. 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.

There isn't much differences in terms of features compared to build 3790.1232, however the "winver" and About Program banners in the Professional SKU now has the "XP" changed to "lh", and the Multilingual User Interface (MUI) feature has been implemented, although it is not functional as the resources located in the MUI are duplicated in the actual file.

While this build uses the Windows Server 2003 Service Pack 1 codebase, this build was compiled before the development reset.

Windows Vista's rewritten Event Tracing for Windows architecture already appears to be implemented in this build, at least to some extent.
