superUser is a simple and lightweight utility to start any process as the System user with Trusted Installer privileges.
Supported operating systems: Windows 11, 10, 8.1, 8, 7, Vista.
The program acquires the TrustedInstaller process' access token and creates a new (user-specified) process as the System user with Trusted Installer privileges using this token.
There are two ways to run the program:
Double-click the executable, grant administrator privileges and wait for a command prompt to appear.
Run superUser from the command prompt opened as administrator, using the following arguments:
superUser [options] [command_to_run]
command_to_run is the command line used to create the new process. It is a filename followed by arguments. If not specified, cmd.exe is started.
This filename can be:
- An executable name (the .exe extension can be omitted).
- A batch name (.cmd or .bat).
| Option | Meaning |
|---|---|
| /h | Display the help message. |
| /m | Minimize the created window. |
| /s | The child process shares the parent's console. Requires /w. |
| /v | Display verbose messages with progress information. |
| /w | Wait for the child process to finish. Used for scripts. Returns the exit code of the child process. |
- You can also use a dash (-) in place of a slash (/) in front of an option.
- Multiple options can be grouped together (e.g.,
/ws).
The /ws options allow you to run a process in a completely transparent way:
- The new process runs in the same window and performs its inputs and outputs there.
- The exit code of the new process is returned and you can retrieve it with the errorlevel variable.
Open a command prompt as administrator to run these commands.
superUser64 /ws whoami /user
superUser64 /ws whoami /groups | find "TrustedInstaller"
superUser64 /w my_script.cmd arg1 arg2
| Exit Code | Meaning |
|---|---|
| 1 | Invalid argument. |
| 2 | Failed to acquire SeDebugPrivilege. |
| 3 | Failed to open/start TrustedInstaller process/service. |
| 4 | Process creation failed (prints error code). |
| 5 | Another fatal error occurred. |
If the /w option is specified, the exit code of the child process is returned.
If superUser fails, it returns a code from -1000001 to -1000005 (e.g., -1000002 instead of 2).
