How to run a powershell script in runonce-Key?

Question

I have a call to powershell.exe that looks like this, and which works from my commandline:

powershell.exe -noexit -command " & 'C:\Test\test.ps1' "

However, when I enter that entry exactly that way in the runonce-key of my current user, nothing happens.

What is the correct way to call powershell.exe passing parameters from runonce or run?

Answer 1

Try with full path:

c:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -noexit "C:\Test\test.ps1" 

or

c:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -noexit -command " & 'C:\Test\test.ps1' " 

Answer 2

A slightly different approach would be to put all your call to powershell.exe with all arguments / parameters into a simple *.bat file, and call that *.bat file from your RunOnce Key. This way you don't need to play around with params, which can mess-up sometimes. Your PowerShell script could even delete that *.bat file, since it is required only once.

Answer 3

Use the File argument instead of command. You can also use some of the other parameters to clean things up (noprofile, sta, and/or WindowStyle)

This is an example of what I use.

C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -noprofile -sta -WindowStyle Hidden -File "C:\Test\Test.ps1"
