Thanks for your reply. I have tried RDC client before but I was after something like RDC manager where I can run multiple servers on one instance as it's easy to switch between VMs.
I was playing around with Remote Desktop (windows app) and that's something which works for me. But I am getting issue when I switch between VMs. Tests fails with error that operation cannot be performed, because the desktop is invisible, on moving to another VM on the same remote desktop instance. I have setup registry settings but still getting the error. Can you please let me know if there's anything else I need to setup to fix this error ?
