How to Launch a Vbscript in Elevated Mode (Run as Administrator)

With the introduction of User Account Control (UAC) in Windows Vista, you usually open an elevated Command Prompt in order to run batch files and scripts that need administrative privileges. Applications can make use of manifest files (using the RequireAdministrator flag) to automatically run elevated.

For scripts, this article provides you some neat little tricks using which you can automatically elevate using the ShellExecute “runas” parameter.

(See also How to Automatically Elevate a Batch file to Run it as Administrator? for another auto-elevation method.)

Launch a Vbscript elevated

Thanks to Jim Barry for tipping me off about the using runas argument in the ShellExecute method of Shell.Application object. Using Jim’s suggestions, my original script was condensed down to a great deal. Use one of these methods to run VBScripts elevated.

Method 1

Here is a sample script that re-launches itself as administrator (elevated) using the runas parameter, if the script has no command-line arguments passed. When re-launching the script as administrator, simply pass a bogus argument so that the script does not run in a cyclic loop.

If WScript.Arguments.length = 0 Then
   Set objShell = CreateObject("Shell.Application")
   'Pass a bogus argument, say [ uac]
   objShell.ShellExecute "wscript.exe", Chr(34) & _
      WScript.ScriptFullName & Chr(34) & " uac", "", "runas", 1
   'Add your code here

End If

Method 2

This method uses a launcher script which runs the main VBScript elevated using the runas verb.

Set objShell = CreateObject("Shell.Application")
Set FSO = CreateObject("Scripting.FileSystemObject")
strPath = FSO.GetParentFolderName (WScript.ScriptFullName)
If FSO.FileExists(strPath & "\MAIN.VBS") Then
     objShell.ShellExecute "wscript.exe", _
        Chr(34) & strPath & "\MAIN.VBS" & Chr(34), "", "runas", 1
     MsgBox "Script file MAIN.VBS not found"
End If

You’ll see see the UAC elevation dialog.

Once user clicks Continue to approve, the main script is launched as administrator.

  1. Found this useful method after reading about it on TenForums – but your page doesn’t display fully on Firefox (78.0.1) even after disabling tracking protection (all ad boxes show spinning circles). It works fine in ‘new’ Edge.
