Bugs and quirks

 * While the Desktop Composition Engine works in this build, the Desktop Composition Engine does not enable Direct3D shaders due to a bug. Because the Aero Glass borders rely on these shaders to function, it is not possible to enable the borders at this time.
 * Search is broken and as a result, it crashes explorer.exe.
 * WinFS is not present.
 * USB Mass Storage is broken.
 * The file saving dialog is broken.
 * Sidebar is not present.
 * This build uses the i386-style setup instead of using.
 * The login screen has no background, defaulting to black instead.
 * The TCP/IP stack is broken, sometimes it functions, sometimes it doesn't.
 * Windows Product Activation is absent.
