On systems that include Terminal Services Process Explorer displays a Users menu that lists the currently connected sessions. Process Explorer creates a menu entry for each session that's name includes the session's session ID and the user logged into the session. Each entry opens a sub menu that has options for disconnecting, logging off, and sending a message to the session's user. In addition, a Properties menu for each session entry opens a dialog box that lists detailed information about the session, including the IP address and name of the client connected to the session.
The contents of the Users menu is updated each time you open the menu to reflect current session information.
