QUSER is a synonym for QUERY USER

Query User returns the following information:

• The name of the user
• The name of the session on the RD Session Host server
• The session ID
• The state of the session (active or disconnected)
• The idle time (the number of minutes since the last keystroke or mouse movement at the session)
• The date and time the user logged on

If you do not specify a user by using UserName, SessionName, or SessionID, a list of all users who are logged on to the server is returned. Alternatively, use a query session to display a list of all sessions on the server. When information for multiple users is returned, a greater than > symbol is displayed before the current session.

A user can always query the session to which the user is currently logged on. To query other sessions, the user must have Query Information special access permission.

The User Access permission type grants the following special permissions: Query Information, Logon, and Connect. These special permissions allow a user to Log on to a session on the terminal server. Query information about a session. Send messages to other user sessions. Connect to another session.

Permissions are set under:

Terminal Services Configuration | Connections | Properties | Permissions | Advanced | Permissions

Powershell

When running quser under Powershell it is useful to split the output into rich objects, this can be done with a regex and ConvertFrom-CSV:

Examples
