Per the tenforums.com article on the same: https://www.tenforums.com/tutorials...-block-suspicious-behaviors-windows-10-a.html Before doing this, I would scroll down in this registry key area and see if the actual mitigations are stored there. If they are not, I believe enabling this option will do nothing. Also after performing the reg. hack, make sure you change the key's ownership back to what it was originally. I assume that was System. I also suspect these 1809 mitigations could possible work on 1803 if the mitigations were added manually via PowerShell and the EnableASRConsumers DWORD reg key value was added. Anyone game for doing so?
