Hi Sandy, thanks for your code and I can set my AppLocker via Powershell. Have you tried to lock "StoreApps" too? I encountered the error "The requested object could not be found" when I changed your sample code from "MDM_AppLocker_ApplicationLaunchRestrictions01_EXE03" to "MDM_AppLocker_ApplicationLaunchRestrictions01_StoreApps03".
