Memory Integrity Page Not Available in Windows 11

Core Isolation is a security feature that helps protect your system from various threats, including some ransomware attacks. If you notice the Core Isolation page or the Memory Integrity setting missing from your Windows Security app on Windows 11, this guide can help you fix the issue.

Memory Integrity Page not available in Windows 11

Method 1: Check Your Windows Security

1.  Press the Windows key, search for “Windows Security” and select the app.

2. Go to “Device security” on the left pane and click on “Core isolation details” on the right.

3. Turn on the “Memory integrity” toggle if it’s disabled and restart your PC to apply the changes.

Method 2: Disable or Uninstall Third-Party Antivirus

Some third-party antivirus programs might conflict with Windows processes. Microsoft Defender Antivirus, a built-in security program, already provides robust protection for your system. Core Isolation is a feature within Defender Antivirus. If you want to make sure Core Isolation working properly, consider temporarily disabling or uninstalling your third-party antivirus software and then restarting your computer.

Method 3: Enable Virtualization from BIOS

Core Isolation or Memory Isolation relies on another feature called Virtualization Technology (VT) to function. If Virtualization is disabled in your BIOS settings, you won’t be able to enable Core Isolation or Memory Integrity. Follow these steps to enable Virtualization Technology in Windows 11:
1. First, open BIOS or UEFI settings on your computer.

2. Navigate to “Advanced Settings” > “System Configuration”.

3. Find the “Virtualization Technology” setting, and set it to “Enabled”.

4. Then, save and exit from BIOS settings.

Method 4: Use Windows Registry to Enable Memory Integrity

1. Type regedit in Windows search and hit Enter.

2. Navigate to the following location in the Registry Editor:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity

3. If the HypervisorEnforcedCodeIntegrity key doesn’t exist, right-click on the “Scenarios” folder and select “New”.

4. Then, rename the newly created key to “HypervisorEnforcedCodeIntegrity”.

5. Select the HypervisorEnforcedCodeIntegrity on the left. Locate an empty space in the right pane, right-click on it, and choose “DWORD (32-bit) Value“.

6. Name the new DOWRD “Enabled”, double-click on it, and set the Value data to “1″.

7. Click “OK” and close the Registry Editor.

8. Then, restart your PC.

Method 5: Reset Windows

Core isolation problems can sometimes be caused by corrupted or missing system files. If the problem continues after trying the previous methods, you can consider resetting Windows 11. This might fix the issue while keeping your issue without erasing your personal data. However, it’s always a good idea to back up your important files before proceeding.

That’s it.
