I am running windows 10 and using hyper-v have created a virtualized windows 7 Pro 32bit machine. I need 32 bit for some older software that we are running.
When I connect up to the virtual machine using the hyper-v manager, everything runs fine but I can not maximize the screen. I am now testing some surface pro tablets and the screen is even smaller.

the enhanced session option is greyed out and cannot be used. I thought about trying to do a remote desktop connection but it will not let me connect to that either. In the virtualized windows 7 machine I have enabled remote desktop connections.

Now these computers are part of a work domain so not sure if that makes a difference.

Any suggestions on how to get the virtualized machines to go full screen?
