On UAC-enabled systems, to make sure a script is running with full admin privileges, add this code at the beginning of your script:
param([switch]$Elevated) function Test-Admin { $currentUser = New-Object Security.Principal.WindowsPrincipal $([Security.Principal.WindowsIdentity]::GetCurrent()) $currentUser.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator) } if ((Test-Admin) -eq $false) { if ($elevated) { # tried to elevate, did not work, aborting } else { Start-Process powershell.exe -Verb RunAs -ArgumentList ('-noprofile -noexit -file "{0}" -elevated' -f ($myinvocation.MyCommand.Definition)) } exit } 'running with full privileges'
