Qui me permet de checker puis d'effectuer les mises à jours Windows.

Mon problème est le suivant : Je dois effectuer ces MAJ sur plusieurs postes/serveurs.
J'aimerais pour éviter me de connecter en RDP puis lancer le script à chaque fois pouvoir lancer ces MAJ comme le faisait un autre de mes scripts :

Code : Sélectionner tout - Visualiser dans une fenêtre à part
get-content C:\Users\test\Documents\Script\Infos\List1.txt |
C'est a dire, récupérer dans la "List1" le nom des serveurs, appliquer le script (donc check + install des MAJ + redémarrage si nécessaire), et c'est tout ou a la rigueur créer un "result.txt" en sortie dans lequel un simple message m'indique "Tout s'est terminé correctement" ou "Des erreures sont survenues".

Si je n'ai pas était assez clair merci de me le préciser.

Cordialement.
