How to: Tell if a PowerShell script is running as the Administrator

$currentPrincipal = New-Object Security.Principal.WindowsPrincipal([Security.Principal.WindowsIdentity]::GetCurrent()) if (-not ($currentPrincipal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator))) { Write-Warning “This script needs to be running as the administrator.” Exit 1 } Write-Host “You are running as the administrator.” This script gets the current Windows Identity, then queries it to find out if it has the appropriate role.
