New features and changes

 * Setup and OOBE have been heavily updated to resemble the RTM, but they use the background that is seen in the official beta build.
 * This build has a new boot screen showing a new progress bar.
 * In addition, the text-mode message "Please wait while Windows sets up your conputer..." has been renamed to "Updating registry settings..." and will now appear as part of the boot screen. If Vista's boot screen is used as fallback, the message still appears at the top left.
 * The login screen is updated to resemble the official beta.
 * Calculator, Paint, WordPad and Sticky Notes have all received numerous updates, taking advantage of the new Ribbon interface for the latter two. Calculator's appearance resembles that of the RTM.
 * The OOBE is now in 1024x768.
 * Display in the desktop dropdown menu has now been renamed to Display Settings.
 * IE8 now shows a "Set Up Windows Internet Explorer 8" window when first opened.
 * Desktop Gadget Gallery supports snapping gadgets to the right side of the screen, however it is buggy and thus it is difficult to take the gadgets out of the snap area.
 * Gadgets are no longer shown by default.
 * Welcome Center no longer appears when logging in.
 * When saving files, folders are shown by default.
 * The system tray resembles that of the RTM.
 * UAC doesn't have a transparent background.
 * Windows Preinstallation Environment was updated with a new background.
 * Accelerators were introduced in Control Panel for Internet Explorer.

Bugs

 * The System Reserved partition is shown in Explorer for no apparent reason.
 * It is not possible to upgrade to this build due to an issue in the method where Windows Setup handles disk volumes.
 * On some machines, setup may fail to create partitions. If this occurs, create a partition, either on another WinPE or on a Linux Live system, such as GParted or Parted Magic.
