Bugs and quirks[edit | edit source]

Desktop Compositing Engine[edit | edit source]

While the Desktop Compositing Engine works in this build, the Desktop Compositing 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.

File Explorer[edit | edit source]

  • Search and cut/copy-pasting are broken as they cause explorer.exe to crash.
  • WinFS is not present. Thus, applications relying on it, such as Outlook Express will crash upon launching.
  • 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.
