Information Windows en Powershell

Voici un petit script qui en dit long sur la version de Windows exécutant le script PowerShell.
Selon les cas, cela peut-être vraiment très intéressant.

   $regset = get-item "HKLM:Software/Microsoft/Windows NT/CurrentVersion"
   foreach( $i in $regset.GetValueNames() ){ 
      Write-Host $i " = " $regset.GetValue($i) 
   }

Ce qui produit le résultat suivant (dont j'ai masqué une partie des valeurs):
