Another option using your original code is to use splatting, which will avoid you from needing to write out the similar Start-Process line twice: Function Start-Elevated { [CmdletBinding()] Param ( [parameter(Mandatory = $true,ValueFromPipeline=$true,Position=0)][String]$Executable, [parameter(Mandatory = $false,ValueFromRemainingArguments=$true,Position=1)][String]$Parameters ) $StartProcessParams = @{} If ($Parameters) { $StartProcessParams.ArgumentList = $Parameters } Start-Process -Verb RunAs -FilePath $Executable @StartProcessParams } This worked on these examples: Start-Elevated 'eventvwr' 'somecomputer' Start-Elevated 'eventvwr' I'll be curious to hear from MBS or others if there is a way to adjust the code MBS provided earlier to account for no parameters since the tuple assignment is definitely cleaner! -Aakash Shah From: listsad...@lists.myitforum.com<mailto:listsad...@lists.myitforum.com> [mailto:listsad...@lists.myitforum.com] On Behalf Of Damien Solodow Sent: Thursday, October 9, 2014 9:20 AM To: powershell@lists.myitforum.com<mailto:powershell@lists.myitforum.com> Subject: [powershell] RE: Better way to accomplish this? Hmm. Problem here is that if I use this to run a command without arguments it throws an exception. So if I do 'start-elevated diskmgmt.msc' it throws an 'Start-Process : Cannot validate argument on parameter 'ArgumentList'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

I tried to make minimal changes and didn't test. My bad. Here is a much shorter (and working) solution. Note the dependence on a tuple assignment.

I forgot about $args. :) The main issue/concern I had with the way I was doing it was that I had to mostly duplicate the Process{} in the If..Else and I was hoping there was a "cleaner" way to do it. Although.. I tested the function you provided, and if I do "Start-elevated -executable notepad test.txt" it tells me that A positional parameter cannot be found that accepts argument 'test.txt' DAMIEN SOLODOW Systems Engineer 317.447.6033 (office) 317.447.6014 (fax) HARRISON COLLEGE From: listsad...@lists.myitforum.com<mailto:listsad...@lists.myitforum.com> [mailto:listsad...@lists.myitforum.com] On Behalf Of Michael B.

There is already a built-in $args variable that accomplishes the same thing. To use the same function, formatted the way I prefer is below. But the question really is (since formatting is a religious argument, not a capability argument) - what problems/concerns do you have with the script/link you posted? What challenge do you need to overcome?

I'm creating a function to invoke a specified executable in an elevated session. The main obstacle right now is around passing parameters (arguments) to the process I'm launching.
