I have some VMs in Hyper-V. Mostly I use vmconnect.exe to connect to them. Using that method of connection, I can press "Ctrl+Alt+Left" to break out of the MSTSC window, and in my workflow, I then press Ctrl+Win+Left to go to the first of two Windows 10 "Virtual Desktops". In this manner, it is simple to switch back and forth from my host to the VM guest.
If I instead use mstsc.exe to connect to the VM, this Ctrl_Alt+Left key combination is no longer available. Is there any key combination that can be user with MSTSC.exe that will allow me to break out of the VM connection? At this point, the only thing that works is to minimise the mstsc.exe app, and then I can shift to the other desktop, which is not efficient.
