Bugs and quirks[edit | edit source]

Desktop Composition Engine[edit | edit source]

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.

Explorer[edit | edit source]

  • Search and cut/copy-pasting are broken as it crashes explorer.exe.
  • WinFS is not present.
  • USB Mass Storage is broken.
  • The file saving dialog is broken if explorer.exe is running.

TCP/IP bug[edit | edit source]

The TCP/IP stack malfunctions most of the time.

Windows Product Activation[edit | edit source]

Windows Product Activation is missing.
