"This setting is managed by your system administrator"

[xenogen]

Attempting to activate Core isolation and Memory integrity. Feature turned on for a second, turned off, and received error message in the title. UEFI boot, secure boot, and virtualization are all activated. I am the administrator with the only user account. My computer is personal. Can anyone help me with this?

Hi xenogen,

it might help if you give us more info on what you were actually doing and with what app(s).

Hi Wolfie,

Thank-you for responding. In the latest version of Windows 1803 (build 17134.1), there is a new feature available that allows you to protect your memory from specific attacks. You access it by going to "Windows Defender Security Center" -> "Device Security" -> "Core Isolation." There, you will see a switch to turn it "on" or "off." In my settings, it's grayed out, with a message above it that says, "This setting is managed by your administrator." It's a built-in feature to Windows that I am trying to activate. I can provide the necessary logs.

UPDATE

Let me add that the message did not display until I attempted to turn the switch on.


Thank-you again.

It appears to be a bug that you can't turn it off again. However, there's a fix involving a registry setting.

O.K. Before I waste any of your time, it is confirmed, that Microsoft screwed up here it seems. The feature is not working properly. I am not the only one getting this error. Take a look at this link, that I found in https://www.tenforums.com

I want to add this for correction, and sorry for the confusion on my part. It looks like option # 2 (the registry key change option) in this tutorial will actually work. It is not recommended to use the steps in rejzor's method unless the tutorial method DOES NOT work for you.

I want to thank personally all those who contributed to this thread.
