Run one of the User commands below to find the session ID (you need to be an administrator on the target machine):

Issues

If you have a blue box highlighting areas of the screen and preventing you from using the keyboard, then switch off Narrator: See Issues.

Connection Bar

I struggled with this, but Ctrl, Alt, Tab does allow me to switch windows.

For more information, see How to show the Connection Bar in a remote desktop session?

If your session freezes (or never gets started), use Control, Alt, Delete to escape. The command will run on your local workstation and will not upset the remote machine.
