Windows Defender says "succeeded" but "program has potentially unwanted behavior."
some kind of H key current user registry setting, I guess, but I don't know if it was part of the Microsoft update or where it might have come from. anyone know? (I'm very limited in my knowledge -- I don't know where to find a list of accepted tags for posts).

I have Windows Defender, Microsoft Security Essentials and of course Windows Firewall with Advanced Security running.

Is that a bad mix?

you no long need defender ,uninstall it

I wondered why defender kept shutting down but was too busy with other things to look into it.

Microsoft security essentials automatically turns defender off when MSE detects defender this is not very clearly stated in early read me files.You can remove or ignore defender MSE will deal with it as necessary. Had same confusion. Later
