Showing the UAC prompt in PowerShell if the action requires elevation

Question

I have a simple PowerShell script to stop a process:

$p = get-process $args
if ( $p -ne $null )
{
$p | stop-process
$p | select ProcessName, ID, HasExited, C

AFAIK, there is no way to do it in the sense that you seem to want. That is running a specified .exe and expecting a prompt to appear immediately.

What I do is for commands that I know have to be run with administrative privs, I run them with a functions I have laying around called Invoke-Admin. It ensures that I'm running as admin and will prompt the user with the UAC dialog if i'm not before running the command.

Here it is

function Invoke-Admin() {
    param ( [string]$program = $(throw "Please specify a program" ),
            [string]$argumentString = "",
            [switch]$waitForExit )

    $psi = new-object "Diagnostics.ProcessStartInfo"
    $psi.FileName = $program 
    $psi.Arguments = $argumentString
    $psi.Verb = "runas"
    $proc = [Diagnostics.Process]::Start($psi)
    if ( $waitForExit ) {
        $proc.WaitForExit();
    }
}
