Hyper-V RDP settings

If you have saved, accidentally or on purpose the Enhanced Mode settings, the dialog is not shown and resolution cannot be changed. In that case you need to close the vm window, the vm can left running, then manually delete the saved Enhanced Mode configuration file. The file is called vmconnect.rdp.XXXXXXXX.config (XXXXXXXX = hexadecimal string representing the machine ID), and is located in %userprofile%\AppData\Roaming\Microsoft\Windows\Hyper-V\Client\1.0
