Elevating a PowerShell script does not work in Windows 11

Question

I am trying to make sure my script runs on elevated PowerShell.

For that, I am using the following snippet:

Verify whether running as Administrator

if (!(Test-Elevated)) {  
    # Stop, and run as Administrator  
    Write-Host 'Not running as Administrator, attempting to elevate...'  
    $arguments = "& '" + $MyInvocation.MyCommand.Definition + "'"  
    Start-Process powershell.exe -Verb runAs -ArgumentList $arguments  
    Start-Sleep -Seconds 3  
    Stop-Process -Id $PID  
}  

I would like to kill the old process, then re-run it on a new, elevated PowerShell process.

This works using a Windows 10 PC, but while trying to run the same script on my Windows 11 Laptop, I get the UAC prompt, I accept, then for a quick second a new PowerShell process opens, and immediately close, without actually executing my script. It seems as if the $arguments are not being included as part of the Start-Process command.

What might be the reason, and solution to this problem?

Answer 1

Do other scripts run fine ? or just problem with running your specific script only?

Answer 2

Was there a resolution? If the script is on a mapped drive, it will lose access to the mapped drive and close. I'm worried that there's a new security feature in Windows 11 that prevents the script from elevating. I don't want the effort to run an automation script to cost more than the script.
