About dialog

Windows Vista build 5000 (vbl_core.040803-2000) is the earliest known post-reset build of Windows Vista, based on a work-in-progress version of the Windows Server 2003 Service Pack 1 codebase.

On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to BetaArchive's FTP server, 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.^[1]

New features and changes[edit | edit source]

Winver[edit | edit source]

The winver and About Program banners in the Professional SKU has been crudely edited to replace the "XP" with "lh", standing for Longhorn.

Longhorn Help Place[edit | edit source]

A new "Longhorn Help Place" button has been added to the Help and Support Center. When clicked, HelpCtr will attempt to launch c:/windows/hsx/helpplace.container, which does not exist in this build, but does in most M5 and M6 pre-reset builds.

Multilingual User Interface[edit | edit source]

Support for the Multilingual User Interface (MUI) feature has been implemented, although it is not functional as the resources located in it are duplicated in the actual file.

Event Tracing[edit | edit source]

The rewritten Event Tracting for Windows architecture has been implemented in this build to an extent.

Bugs and quirks[edit | edit source]

Windows Explorer[edit | edit source]

The details pane in Windows Explorer does not function correctly, while panes and tasks that work cannot be opened or closed. In the Control Panel, they also quickly dissapear after loading, making it almost impossible to switch to Classic View. This issue can be resolved by disabling the "Fade or slide menus into view" option in the Performance Options.

Out-of-box experience[edit | edit source]

The animated "Question Mark" assistant in the Out-of-box experience does not appear until the second page of OOBE is reached, which may be due to bugs in the Microsoft Agent technology itself.
