QUERY USER is a synonym for QUSER.exe

Available to 64 bit sessions only, there are no 32 bit implementations of QUSER.exe (QUERY USER).

Query User returns the following information:

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 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


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:

(quser) -replace '\s{2,}', ',' | ConvertFrom-Csv

Alternatively the script Get-LoggedOnUser.ps1 will also show disconnected sessions.


Display information about all users logged on the system:

C:\> query user
