How to run an application as "run as administrator" from the command prompt?

Question

I have a batch file called test.bat. I am calling the below instructions in the test.bat file:

start /min powershell.exe %sysdrive%\testScripts\testscript1.ps1

When I run this through the command prompt, my testscript is running successfully. I want to run it as administrator (as if I have created a desktop shortcut and run as administrator. It shouldn't prompt for any username or password).

I have tried adding /elevate and /NOUAC parameters in the above test.bat, but no luck. How do I fix this issue?

I know how to do it manually, but I want this to be executed from the command prompt.

Answer 1

Try this:

runas.exe /savecred /user:administrator "%sysdrive%\testScripts\testscript1.ps1" 

It saves the password the first time and never asks again. Maybe when you change the administrator password you will be prompted again.
