Bugs and quirks[edit | edit source]

Installation[edit | edit source]

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

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.
