Bugs and quirks[edit | edit source]

Desktop Compositing Engine[edit | edit source]

While the Desktop Compositing Engine functions correctly, Direct3D shaders are not enabled due to a bug. As the DCE window frames rely on these shaders to function, it is not possible to enable them in this build.

File Explorer[edit | edit source]

Searching and cut/copy-pasting is not functional, as attempting to do so will cause an explorer.exe crash.
WinFS is not present. Thus, applications relying on it, such as Outlook Express will crash upon launching.
The USB Mass Storage feature is non-functional.
The file saving dialog is non-functional.
