RunElevated.bat: Run an Elevated command on Windows
Posted by jpluimers on 2025/09/02
For a long time, I have ran with the runelevated.bat in [Wayback/Archive] Run an Elevated command using that: “net file” returns errorlevel 1 when not UAC, and “PowerShell Start-Process” has a “-Verb RunAs“; see the answers at http://stackoverflow.com/questions/7044985/how-can-i-auto-elevate-my-batch-file-so-that-it-requests-from-uac-admin-rights for more information
By now, I would just prepend this oneliner into each batch-file needing elevation:
@pushd "%~dp0" & fltmc | find "." && (powershell start '"%~f0"' ' %*' -verb runas 2>nul && popd && exit /b)
Both the initial batch file and one-liner are from [Wayback/Archive] windows – How can I auto-elevate my batch file, so that it requests from UAC administrator rights if required? – Stack Overflow (thanks [Wayback/Archive] Ir Relevant, [Wayback/Archive] ceztko, [Wayback/Archive] Jamesfo, and [Wayback/Archive] PDixon724)
Note that the net file trick below should actually be repeated twice. This is explained in [Wayback/Archive] windows – Batch script: how to check for admin rights – Stack Overflow (thanks [Wayback/Archive] zumalifeguard), but wait: there is even a better solution!
The fltmc trick above works much better than the net file trick and is available from Windows XP and up, see [Wayback/Archive] windows – Batch script: how to check for admin rights – Stack Overflow (thanks [Wayback/Archive] npocmaka).
Oh: on systems where I have full installation control, I always install gsudo, see gsudo (sudo for windows).
