Microsoft Endpoint Configuration Manager est capable de supprimer automatiquement le contenu des mises à jour logicielles des points de distribution lorsque ce contenu est lié à des mises à jour expirées. Ce processus permet de gérer l’espace disque sur vos points de distribution en supprimant tout contenu dont vous n’avez plus besoin.

Si celles-ci ne se trouvent dans aucun groupe de mises à jour logicielles, ConfigMgr purgera automatiquement les mises à jour expirées après 7 jours. Vous pouvez modifier le nettoyage à 0 jour si vous souhaitez que les composants wsyncmgr suppriment immédiatement les mises à jour expirées (en supposant qu’ils ne soient pas dans un groupe de mises à jour logicielles). On appelle ce nombre de jours, âge de nettoyage des mises à jour (Updates Cleanup Age)

Ci-dessous un script VBS qui permet de changer la valeur de l’âge de nettoyage des mises à jour sur votre ConfigMgr :
