Fix Core Isolation Memory Integrity Page not available in Windows 11

If the Core Isolation Memory Integrity Page is missing or not available on your Windows computer, follow the solutions mentioned below.

1. Enable Virtualization Technology from BIOS
2. Enable Core Isolation in a Clean Boot state
3. Repair and/or Reset Windows Security program
4. Disable or uninstall third-party antivirus
5. Reset your computer

Before you begin, make sure that you have updated Windows OS, along with the device drivers and your BIOS.

1] Enable Virtualization Technology from BIOS

Core Isolation is a Virtualization-based security feature. If Virtualization Technology is disabled, you will not be able to access Memory Integrity or Core Isolation. To resolve the issue, we need to enable Virtualization Technology from BIOS. Follow the steps mentioned steps to do the same.

1. First of all, boot into BIOS or UEFI.
2. Navigate System Configuration and then go to Virtualization Technology.
3. You need to select Enabled and save and exit from BIOS.

Do keep in mind that the steps mentioned earlier are for HP computers, if you have one from a different manufacturer, check our post to enable Hardware Virtualization.

2] Enable Core Isolation in a Clean Boot state

There are a lot of programs that can potentially interfere with genuine Windows services, including Core Isolation. Most of them are security programs, but it is possible that a non-security application comes preinstalled with a security feature that is causing this whole conundrum.

To find it out, we need to start the system in a Clean Boot state and then enable Core Isolation. If you can turn on Core Isolation in the Clean Boot state, enable the services manually to find out what’s causing the problem. Once you know the culprit, disable it and your issue will be resolved.

3] Repair and/or Reset Windows Security program

Windows Security is just like any other program installed on your computer. You can pretty easily reset or repair Windows Security from Windows Settings. Before we do that, make sure to close the app from Task Manager as that will kill all of its running instances. Once you have closed Windows Security, follow the below steps to repair or reset it.

1. Open Settings by Win +I.
2. Go to Apps > Installed apps.
3. Search for “Windows Security”, if it’s not there, click on System Components.
   • Windows 11: Click on the three dots and select Advanced Options.
   • Windows 10: Select it and click on Advanced Options.
4. Finally, click on Repair.

If repairing the app is to no avail, click on Reset. Hopefully, this will do the job for you.

4] Disable or delete third-party antivirus and then restart your computer

It came to our attention that some of the victims have had installed a third-party antivirus such as Norton or Avast on their computer. These security programs are actually not needed for Windows as Microsoft has already installed a built-in security program of which Core Isolation is a part. If you want to keep using Core Isolation, you must disable or delete these programs and then reboot your computer.

It is best to use a free security software uninstaller tool released by them to uninstall it completely.

5] Reset your computer

You will get this issue due to misconfiguration or corrupted system files, we need to use Reset This PC, or Cloud Reinstall to reset every Windows component. You can also use In-place Upgrade Repair and see if that helps.

Hopefully, this resolves the issue for you.
