What is Memory Integrity in Windows?

To understand Memory Integrity, you must first know the Core Isolation feature. Core Isolation provides added protection against malware or other forms of hacking attacks.

It protects by isolating your important computer processes from your operating system and device. Memory Integrity is a part of core isolation designed to prevent malicious code execution.

Memory Integrity is also known as Hypervisor-protected Code integrity (HVCI). Its sole purpose is to prevent malicious software and programs from accessing drivers or gaining control over high-security processes.

How to Fix Memory Integrity is Turned Off on Windows 11?

5. To disable Memory Integrity, enter 0 on the Value data field and click the Ok button.

3. Identify and Fix Driver Problems

Driver problems are one of the most prominent reasons Memory Integrity is disabled on Windows 11. The best way to deal with this is to identify and fix the existing driver issues. Here’s what you need to do.

1. First, click on the Windows search and type in Device Manager. Next, open the Device Manager app from the list.

2. When the Device Manager opens, check for the installed drivers with a yellow exclamatory mark at the end.

3. Those are incompatible drives. You need to right-click on them and select Update Driver.

4. Select the Search automatically for drivers option on the next screen. This will download the latest version of driver from the internet and will install automatically.

4. Remove all incompatible drivers

If the Memory Integrity is off due to Driver incompatibilities, you will find an error saying, ‘Resolve any driver incompatibilities and scan again’.

You must click the Scan again button on the Core isolation screen to find all incompatible drivers.

Once you find the incompatible driver, note down the Published Name and follow the steps below.

1. Open Windows 11 search and type in Command Prompt. Right-click on the Command Prompt and select Run as administrator.

2. When the Command Prompt opens, execute the command:

pnputil /delete-driver (driver's published name) /uninstall /force

Important: Replace the (driver’s published name) with the name you have noted in the Core Isolation screen.

For example: pnputil /delete-driver oem27.inf /uninstall /force

This will remove the incompatible driver from your device. Now restart your Windows 11 PC to install the compatible driver version.

5. Fix Corrupted System Files

Corrupted system files are another reason Memory Integrity is off issue on Windows 11. Hence, you can run the System File Checker (SFC) utility to find and repair the corrupted files.

You can use the Command Prompt to run the SFC utility on your Windows 11. For that, follow the steps we have shared below.

1. First, click on the Windows 11 search and type Command Prompt. Next, right-click on the Command Prompt and select Run as administrator.

2. When the command prompt opens, execute the command:

sfc /scannow

3. Now, you need to wait until the scan completes. If the scan returns an error, execute the below command:

DISM /Online /Cleanup-Image /RestoreHealth

Once the scan is complete, restart your Windows 11 PC and try to enable memory integrity again. This time, the security feature will be turned on without any issue.

6. Update your Windows 11

Keeping the operating system up-to-date is an evergreen method for eliminating bugs and security issues.

Timely updates are important, especially if you want to use new features and security patches. For example, the version of Windows you are using has a bug preventing you from enabling the Memory Integrity Core isolation feature.

The best you can do is update the operating system. For example, to update Windows 11, head to Settings > Windows Update > Check for Updates.

These are some of the best ways to resolve the Memory Integrity is off issue on Windows 11. However, it’s an essential security feature and should be turned on. If you need more help dealing with memory integrity problems, let us know in the comments below.
