Setup
Setup overall is similar to previous builds of Windows Longhorn.

Changes

 * MyTVApp has been removed.

Installation

 * In some cases, either a BSOD or freeze might happen after the  screen upon first installation reboot. If that happens, simply reboot the machine again to access the hardware portion of setup.

Desktop Composition Engine
While the Desktop Composition Engine works in this build, the Desktop Composition Engine does not enable Direct3D shaders due to a bug. Because the DCE window frames rely on these shaders to function, it is not possible to enable them at this time.
