Execute a program under a different user account (non-elevated).

      RUNAS [ [/noprofile | /profile] [/env] [/savecred | /netonly] ]
         /user:UserName program

      RUNAS [ [/noprofile | /profile] [/env] [/savecred] ]
         /smartcard [/user:UserName] program

      RUNAS /trustlevel:TrustLevel program

   /noprofile       Do not load the user's profile.
                    This causes the application to load more quickly, but
                    can cause some applications to malfunction.

   /profile         Load the user's profile. (default)

   /env             Use the current environment instead of user's.

   /netonly         Use the credentials for remote access only.

   /savecred        Use credentials previously saved by the user.
                    This option is not available on Windows 7 Home or
                    Starter Editions and will be ignored.

   /smartcard       Load the credentials from a smartcard.

   /user            UserName in the form USER@DOMAIN or DOMAIN\USER

   /showtrustlevels Display the trust levels that can be used.

   /trustlevel      Level should be one of levels enumerated
                    in /showtrustlevels.

   program          The command line .EXE to run.

/profile is not compatible with /netonly.
/savecred is not compatible with /smartcard.

When you start a program with RunAs /netonly, the program will execute on your local computer as the user you are currently logged on as, but any connections to other computers on the network will be made using the user account specified.

Without /netonly everything will run under the user account specified.

RUNAS used backslash \ as an escape character (not the standard ^ used by other CMD commands).
RunAs Reqires the "Secondary Logon" service to be running.

The error level %ERRORLEVEL% returned by RunAs: success=0, failure=1

Run with Elevated permissions

In Windows Vista and above, you can run a script with elevated permissions by right clicking and choosing "Run As Administrator"

The RunAs command predates elevation, so it has no switch for running an elevated command.
An alternative is to invoke the UAC dialogue by calling the VBScript .ShellExecute function.

When a script is run with elevated permissions several aspects of the user environment will change: The current directory, the current TEMP folder and any mapped drives will be disconnected.

RunAs from Windows Explorer

Select an executable file, Shift-Right-click and select Run As..
This option can be hidden by setting


Run notepad.exe as the user Jdoe on domain SS64dom with no profile:

Run CMD.exe as the Administrator on the local machine Dellpc64:

C:\> Runas /profile /user:DELLPC64\administrator CMD

Run Notepad.exe as 'Natasha' on domain SS64dom using the current environment, and open a file, escape the quote characters around the filename with \ :

C:\> Runas /profile /env /user:SS64Dom\natasha "notepad \"C:\work\demo file.txt\""

Run Active Directory Users and Computers (dsa.msc) as the user Jdoe on domain SS64dom
