Bugs[edit | edit source]

Installation[edit | edit source]

It is impossible to upgrade to this build, as it will cause lsass.exe to throw out errors, and the system will become stuck in a bootloop. The only workaround is to reinstall Windows.

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.
