Specifies a set of user credentials to use for all subsequent uses of Run and RunWait.

RunAs , User, Password, Domain



If this and the other parameters are all omitted, the RunAs feature will be turned off, which restores Run and RunWait to their default behavior. Otherwise, this is the username under which new processes will be created.


User's password.


User's domain. To use a local account, leave this blank. If that fails to work, try using @YourComputerName.


If the script is running with restricted privileges due to User Account Control (UAC), any programs it launches will typically also be restricted, even if RunAs is used. To elevate a process, use Run *RunAs instead.

This command does nothing other than notify AutoHotkey to use (or not use) alternate user credentials for all subsequent uses of Run and RunWait.

ErrorLevel is not changed by this command. If an invalid User, Password, or Domain is specified, Run and RunWait will display an error message explaining the problem (unless their UseErrorLevel option is in effect).

While the RunAs feature is in effect, Run and RunWait will not able to launch documents, URLs, or system verbs. In other words, the file to be launched must be an executable file.

The "Secondary Logon" service must be set to manual or automatic for this command to work (the OS should automatically start it upon demand if set to manual).
