Windows 11 - Core isolation: This setting is managed by your administrator

Question

Hi, I use Windows 11 and in the menu:

• Windows security
• Device security

On "Core isolation" I find:

"This setting is managed by your administrator"

Memory integrity slide is greyed off but is setted to ON

I checked also in the registry and I verified that is ON, but I wannna disable "This setting is managed by your administrator" and have the possibility to set this option ON or OFF manually.

Someone could help me to fix this issue ?

Thanks in advance.

Answer 1

I know this is an old post, but it's still the first thing that came up when I was searching for a solution to this. Hopefully this will save someone else.

To remove the message "This setting is managed by your administrator" from the Core Isolation, Memory Integrity toggle, run the following command in an elevated Windows command prompt.

reg add HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity /v "WasEnabledBy" /t REG_DWORD /d 2 /f

That will add a Reg_Dword called "WasEnabledBy" to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity and set its value to 2.

You may need to reboot but I didn't.

Answer 2

Open Registry Editor.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios.

Make sure HypervisorEnforcedCodeIntegrity is set to 1 to enable Memory integrity.

Answer 3

This did not solve my problem. My settings are still blocked and "manage by administrator".
