I have Windows 10 enterprise x64 1903 18362.592 which has been installed for at least 6 months. I had windows defender disabled via group policy. Since a recent update defender real time scanning gets turned on every time I reboot. This is my group policy settings Why is Defender turning itself back on at reboot? How can I force it to stay off? I do lots of development and the real time scanning interferes with benchmarks and slows out build process down massively. I tried the exclusion folders but it doesn't respect these settings when doing a real time scan.
