Bugs[edit | edit source]

Upgrade[edit | edit source]

Upgrading to this build will cause lsass.exe to throw out errors, and the system will become unbootable. This bug does not affect clean installation, as it will boot up properly.

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.
