Once you start using your virtual PC, how do you get control back to the host PC? The help document of VPC says to press the host key, but what on earth is the host key? It’s the right ALT key of your keyboard. Not any ALT key, but the RIGHT ALT key. Press it and the mouse control comes back to your host PC.
You can launch your virtual PC in full screen mode. Once you have done that, how do you quit full screen mode? Again, press host key and enter. That is RIGHT ALT + Enter.
Simple, yet it took me some time to figure it out.
