Configurez l'état et les éléments pour générer les sorties .reg, PowerShell, Intune et SCCM.

Ces exports reproduisent l'effet registre de la stratégie. Modifier le registre directement n'équivaut pas à appliquer la GPO via la console (pas de gpupdate, pas de suivi centralisé). Testez avant la production ; HKLM nécessite des droits administrateur.
