Is there any remote desktop software for Windows that can access a computer, but not showing your session on the computer of the host and vice versa?
So for example:
Someone at the hostcomputer logs in as user A. And you login as user B at the same time. The person on the hostcomputer only sees session A and you the one who uses the remote desktop only sees session B. Like a kind of dualscreen configuration, but with the second screen taken by the remote desktop user.
