Windows Security's Core Isolation features are missing and unable to turn on

Question

Hi Colleague,

I have reinstalled my windows many times and most of the features under the windows security are missing. Previously when I clicked on the Window security and nothing is displayed and it is blank screen. Fortunately, now at least is showing some incomplete features. Below is just a tip of the iceberg which I would like to share with you. As for the Memory access protection which is showing "The setting is managed by your administrator" is ridiculous. I have used the command below to create an Administrator and logged in as a Administrator with an administrator privilege. However, it is still showing "The setting is managed by your administrator". I thought I am already an Administrator with administrator privileges.

Please provide guidance on how to regain all window security features back after reinstallation of windows. Do I need to enable on group policy or registry after reinstallation? I am wondering if there is some profiling on my window pc without my approval as the memory integrity is turning off by itself frequently. Please help.

Command to create user Administrator.

===========================

Powershell - net user Administrator /active:yes

Control Panel\All Control Panel Items\User Accounts\Manage Accounts\Change an Account\Change P

Windows Security > Core Isolation

===================================

1. Memory Integrity - (turned off by default)
2. memory access protection (The setting is managed by your administrator)
3. Kernel-mode Hardware-enforced Stack protection (Missing)
4. Microsoft Vulnerable Driver Blocklist (Missing)
5. Microsoft Defender Credential Guard (Missing)
6. Local Security Authority Protection (Missing)

Hello,

Thank you for posting in Q&A forum.

If some Windows features don't work properly or Windows crashes, use System File Checker to scan Windows and recover your files. Open cmd as an administrator and run the following command to see if it can fix the problem:

DISM.exe /online /cleanup-image /restorehealth

SFC /SCANNOW

I hope the information above is helpful.

Best regards
