Windows 10: Defender - "This setting is managed by your administrator"

I got fed up with AVG finally and fully uninstalled it with their removal tools. Now I'm trying out Windows Defender to see how I manage.

But under "Virus & threat protection settings", I can't enable Real-Time protection.It's greyed out and says, "This setting is managed by your administrator".

I have shutup10 installed so I'm wondering if that is blocking it, but I don't know which setting would do this. At first, all 4 settings in shutup10 for "Windows Defender and Microsoft Spynet" were enabled (blocked), and Defender wouldn't even turn on. I disabled all 4 in Shutup10 and now Defender is running, but I still can't enable Real-Time protection so I'm thinking something in Shutup10 might still be preventing it.

Any suggestions on what to try? I tried disabling everything one section at a time in Shutup 10 but unless I missed something it hasn't helped. Maybe it's something else?

Settings can't be opened using the built-in administrator account


Hello,
Unfortunately I have the same issue as Dabz from upgrading win7 to win10.
I've tried opening settings using all the suggested methods and it will not load using my account with Administrator access nor the built-in Administrator profile. I also tried other methods not listed such as using Run. Control panel is just a stepping stone to add users in Settings.
I'm also having explorer.exe issues, which I believe is preventing Settings from loading.
Using cmd (Admin) I successfully created a new user profile [and granted admin access also using cmd (Admin)], however win10 will not allow this account to log on. win10 does not list this new user within control panel but it does in the start menu. win10 will not allow to log in or switch to the new account via the start menu either.
I can access settings in Safe Mode but this will not allow me to create a new account.
Any help/suggestions will be greatly appreciated.
Cheers

Try creating an SRP (Software Restriction Policy) in Windows 10 Home. It has no effect.




Settings are totally ignored. The file still launches.





That's just one example.

Could it be that key combo has been reassigned by something else?

And have you otherwise verified the ALT key is working?

And it may be that ALT + Enter no longer works in Win 10 for whatever obscure reason - it's not a Windows key combination, but specific to programs. Why am I suggesting this? Because on a superficial search, others are having problems with it too...

Why doesnt Alt+Enter fullscreen work in Windows 10? - Super User
- suggests perhaps using F11
