Windows Vista build 5001

Windows Vista build 5001 is among one of the first builds of Windows Vista to be compiled after the development reset of Windows "Longhorn". Images of this build were released by UX.Unleaked on May 1, 2008. On January 23, 2020, Grabberslasher, the owner of the website, announced that this build would be released to BetaArchive. It was later released in the third set of his 33 Longhorn/Vista builds on January 26, 2020, alongside build 4048 and multiple compiles of build 5000.

Changes
Despite being similar to Windows XP due to it being compiled early on in its development, this build still has a not entirely insignificant number of changes due to the busy nature of Microsoft around the reset and the fact that almost a month separates this and build 5000.

Default Wallpaper
This build has a new default wallpaper, which is simply Bliss with a Texas Longhorn bull added. Alongside this, the banners in "About Windows" have been updated to say "lh" instead of "XP". These rebrands, which are hastily made, raised doubts from many people prior to the release of this build.

Portable Media Devices control panel option
The Control Panel includes an option called "Portable Media Devices", which was not included in build 5000.

This is due to Windows Media Player being updated from 9 Series to 10, although the icon to the program is missing in the Start menu.

User-Mode Driver Framework
The User-Mode Driver Framework has been implemented in this build.

Minor changes
The background of the User Accounts control panel option has been changed from blue to grey.

Longhorn Help Place
In builds 5000 and 5001, a "Longhorn Help Place" button has been added to the Help and Support Centre. Upona ttempting to launch it, HelpCtr will attempt to launch, which while not existing in this build, does exist in some Longhorn pre-reset M6 builds, such as [[Windows Longhorn build 4033|4033[]. It will appear to do nothing as none of the files required to launch helpplace exist in this build.

Bugs
This build has a not entirely insignificant number of bugs, likely due to the significant changes being made under the hood to the operating system around this time (the first 5000 build was compiled almost two months before this build)


 * The details pane in Windows Explorer is broken, as well as several other panes and tasks such as the ones in Control Panel.
 * The panes and tasks that do work cannot be opened or closed.
 * The Out of Box Experience (OOBE) crashes when loading the desktop on first boot.
 * Classic view in Control Panel is almost impossible to access due to bugs, as the option disappears almost immediately after it is selected unless you are extremely quick with your viewing
 * There is a small bug with theme previewing.
 * It is possible to get an endless loop of error messages asking you to insert the currently inserted disc.
 * Right-clicking on any file in Explorer causes DEP to block Explorer from executing data as code. Explorer immediately crashes and is automatically restarted after the user clicks OK on the DEP message box.
