It is possible to take control of Session 0 from another user.
A user who is currently connected to Session 0 cannot prevent a session takeover. Furthermore, Windows provides no advance warning prior to a session takeover.
To steal control of Session 0, simply click the Steal From menu item.
Note: The RDP user is listed along with the client machine name. It is also possible to kick a user off Session 0 and leave it unoccupied.
This function is useful for cleaning up orphaned Session 0 connections, e.g. when a user connects to a remote server through RDP, switches to Session 0, and then disconnects the RDP session, thus leaving Session 0 inadvertently occupied.
For information about command-line parameters that are used to take control of Session 0, see Command Line Parameters.
