Suddenly when I open windows 7 and it seems that all work ok In the welcome screen, I can see only cursor and black window. So I can't do nothing.
Same problem for me, only way to fix is to turn off video hardware acceleration. But then everything is so slow How to fix this?
Try DirectX 9 instead of 10. Does that fix? Also recommend uninstall Parallels Tools from Windows, then reinstall again.
