Is there a seamless rdp mode for windows?
Solution 1:
You cannot Alt-Tab between RDP sessions, since it is transmitted to the remote session and is not handled locally.
The product Royal TS is an RDP client program that offers more features than the standard Windows Remote Desktop Client. Version 1.5 is still freeware.
This product does use the Windows Remote Desktop ActiveX, same as RDP, but in its own windows. These windows can be embedded in tabs, which makes it easier to move between the sessions.
