Windows Vista build 5284 (vbl media ehome)

This build leaked at the date 2016-12-19. It includes new volume control and network icons, eHome features for Media Center, and notably a custom installer, allowing user to choose between Home Premium and Ultimate (however the regular one is also available to install the Server SKU). The $OEM$ folder in the /sources folder must be deleted or setup will fail with an "An error occurred while copying privates" message. Alongside, upgrading will not work as setup will fail to copy the temporary files. It is also the last build to have at least 1 reference to Longhorn.
