Parallels 14 with Win 10 Pro. I changed several settings for the Tastatur and set windows to Standby after that. I quited parallels and after restart parallels my windows was in Standby. By reactivating Windows i see only a Black Screen. Shut down Windows with right mouse-click in the Control-center does not function.
Hy, meanwhile I solved the problem by myself. Shutting down the VM was successful. After restart the VM works fine.
