Setting up non-administrative control of Hyper-V through PowerShell–Updated

Yesterday, I told you about how it was now easier to allow a non-administrative user to control Hyper-V.  This is nice – but it does mean that this script that I blogged about 4 years ago no longer works.  Here is a new one:

 $myWindowsID=[System.Security.Principal.WindowsIdentity]::GetCurrent()
 $myWindowsPrincipal=new-object System.Security.Principal.WindowsPrincipal($myWindowsID)
  
 # Get the security principal for the Administrator role
 $adminRole=[System.Security.Principal.WindowsBuiltInRole]::Administrator
  
 # Check to see if we are currently running "as Administrator"
 if ($myWindowsPrincipal.IsInRole($adminRole))
    {
    # We are running "as Administrator" - so change the title and background color to indicate this
    $Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)"
    $Host.UI.RawUI.BackgroundColor = "DarkBlue"
    clear-host
    }
 else
    {
    # We are not running "as Administrator" - so relaunch as administrator
  
    # Create a new process object that starts PowerShell
    $newProcess = new-object System.Diagnostics.ProcessStartInfo "PowerShell";
  
    # Specify the current script path and name as a parameter
    $newProcess.Arguments = $myInvocation.MyCommand.Definition;
  
    # Indicate that the process should be elevated
    $newProcess.Verb = "runas";
  
    # Start the new process
    [System.Diagnostics.Process]::Start($newProcess);
  
    # Exit from the current, unelevated, process
    exit
    }
  
 # Prompt for the virtual machine to use
 $Domain = Read-Host "Specify the domain of the user to add to Hyper-V Administrators (use $($env:ComputerName) for this computer)"
  
 # Prompt for the path to export to
 $User = Read-Host "Specify the username of the user to add to Hyper-V Administrators"
  
 $HvAdmins = [ADSI]"WinNT://$env:COMPUTERNAME/Hyper-V Administrators,group"
 $HvAdmins.Add("WinNT://$($Domain)/$($user),user")

This script will add any user you specify to the local “Hyper-V Administrators” group.

Cheers,
Ben
