ok an update.
Firstly when I had the beta option enabled, I was getting UAC prompts on bootup from some of my startup apps that dont normally trigger a UAC prompt, odd behaviour, it went away when I downgraded the protection.
Second, the protection does not appear to be fully working, it appears it doesnt solely rely on SRP, as I think the non SRP protection is working, I know because if I change my time zone, it triggers a prompt asking me to approve the cpl loading as filtered by cryptoprevent.
However if enabling the advanced interface, there is a test button, pressing that button the test fails, and if I manually check the SRP config I can see none of the settings are applied. I have been busy so not looked into this too much yet, but did read on wilders security AV apps can block cryptoprevent from working properly so I suspect nod32 may have blocked it possibly.
See my attached screenshot, the filtering stuff top right is whats working, but the SRP on the left is not.
