Has anyone used Defender Application Control policy in SCCM yet? I have a basic policy with the "Authorize software that is trusted by the Intelligent Security Graph" option enabled. Once my test PC checks in, notepad doesn't work and if I reboot, the system is bricked and won't boot. Says it can't access a txt file that is used for event logs. I would have thought the Intelligent Security Graph option would at least let Windows boot....
