Symptoms

• Windows is frozen and not working, however Parallels Desktop application and macOS work properly
• Once I launch Windows I get black screen

Cause

Such issues also happen on a real PC, this is Windows related issue caused by hanging vital system processes or malfunctioning drivers.

Resolution

To revive Windows a simple system force restart helps on the real PC.

To force restart Windows in Parallels Desktop go to Actions on Mac menu bar > click Reset.

If you use a virtual machine in Full Screen view mode move the mouse to the top of the screen and wait for 1-2 seconds to open the Mac menu bar. To release the mouse input and access the top menu bar easier, press Ctrl + Alt shortcut.

Note: To avoid such issues in the future, we recommend disabling Windows built-in fast startup feature. If resetting Windows did not help or Actions menu is unresponsive please follow the steps from KB 6338.
