Windows Vista build 5284 (vbl media ehome)

Windows Vista build 5284 (vbl media ehome) is a Beta 2 build of Windows Vista. This build was leaked by BetaArchive user marcoguy on 2016-12-19. Since this is an eHome build, there are features dedicated to this development branch, mostly for Windows Media Center. This is the last build of Vista to have at least one Longhorn reference, and also the last leaked build to be compiled in 2005.

Setup
Since this is an eHome build, a Media Center DVD Launcher will appear upon booting into setup, giving you the option of running setup manually or installing now from the DVD launcher. This DVD launcher replaces the setup autorun that appears usually upon boot.

If manually installing, you will essentially go through the same setup layout as previous builds of Vista. This setup layout is practically the same as previous builds of Vista, asides from the EULA being changed once again.

If using the DVD launcher to set up, you will be given a warning before proceeding to format the hard drive. If choosing to continue, you will be taken straight to the copying files page. After restarting, it's essentially the same procedure as manually installing.

New features and changes

 * This build has a few new icons, such as the sound tray icon being updated to a simplistic flat-white one.
 * Relating to the sound tray icon, this also shows even if there are no sound drivers installed. It also has a new volume popup, which is similar to that found in the RTM.
 * The sidebar process was introduced back into this build, however it will not open.
 * Windows Explorer has been organized in a more cleaner design and also has new icons.

Start menu
The start menu has received a few minor uplifts. The icon of the hibernate button has been changed, alongside its color. The icon for the user's profile picture is now inside the start menu range itself, rather than popping out. For this very reason, the start menu is slightly larger by default than aforementioned builds.

Internet Explorer
A new button next to the star before the tabs section has been added, which resembles a + symbol. It is an addition to the pre-existing star button, which manages favorite websites even further. The toolbar underneath the tabs has been removed too.

Windows Sidebar

 * The Windows Sidebar comes back after being absent since Windows Vista build 5212, but here, it is non-functional and thus it doesn't open as a result.

Bugs

 * Help and Support will not launch properly and will either crash Windows Explorer or itself.

Installation
This build cannot be upgraded as setup will fail to copy the temporary files. Alongside, the $OEM$ folder in the /sources folder must be deleted or setup will fail with an "An error occurred while copying privates" message, whether you're upgrading or not. The eHome OEM features in this build are only known to install properly on real hardware.
