5 Ways to Fix the Memory Integrity Feature Grayed Out on Windows 11


Does the memory integrity feature in Windows Security appear grayed out? Is your PC saying, “Memory integrity is off. Your device may be vulnerable,” but you can’t turn on the toggle? The memory integrity feature prevents malicious software from accessing high-security processes when your device is invaded by malware.


But what causes this feature to be grayed out? In this article, we’ll discuss why you cannot turn on this feature and how to identify and fix the underlying problem.


What Causes Memory Integrity to Become Grayed Out on Windows 11?

The primary cause of memory integrity not working on Windows 11 is your drivers. When they become outdated or corrupt, you are likely to run into this problem. Likewise, if your system is outfitted with incompatible drivers, the memory integrity feature may stop working.

The error message itself usually explains where the problem lies, so fixing the problem is simple. You can fix faulty drivers, repair corrupted system files, update your operating system, revert an update, or remove incompatible drivers. Let’s discuss some fixes to get the feature working again.

As you apply each fix listed below, go to the Windows Security app and try enabling memory integrity again. It will help you identify what was causing the problem and fix it quickly without going through unnecessary fixes.

1. Identify and Fix Driver Issues

In most cases, the primary cause of the problem under discussion is outdated or incompatible drivers, so let’s start by checking your drivers. Before you go ahead and troubleshoot driver issues in the Device Manager, do the following:

  • If you have recently installed a third-party driver and had problems with memory integrity afterward, uninstall it.
  • Open the Windows Security app, click on the Device security tab from the left sidebar, and click on Core isolation details.
    Clicking on the Core Isolation Details Option in the Device Security Tab of Windows Security App

  • Here, enable Memory integrity. If you encounter an error saying, “Resolve any driver incompatibilities and scan again,” click on the Review incompatible drivers link.
    Clicking on the Review Incompatible Drivers Link in Core Isolation Settings of Windows Security App

  • Then, note down any drivers Memory Integrity suspects are incompatible.

Following the above checks, follow these steps to rule out driver-related problems:

  1. Right-click on the Windows Start button and select Device Manager.
  2. Go to the View tab and click Show hidden devices.
    Clicking on the Show Hidden Devices Option in the View Tab Dropdown Menu Of Windows Device Manager App

  3. Look for the device that has a yellow triangle on it with an exclamation mark inside it or the driver(s) with problems indicated by the Memory integrity.
  4. Right-click on that device and select Update driver.
    Clicking on the Update Driver Option by Right-clicking on the Incompatible Driver in Windows Device Manager App

  5. If updating the driver does not solve the problem, right-click it and select Properties.
  6. Under the General tab, read the message in the Device status box.

  7. Take note of the error code and visit the official Microsoft Support documentation where all Device Manager-related errors are listed.
  8. Find the relevant code information and apply the Microsoft recommended fix to fix the problem.

What if applying the Microsoft recommended fix doesn’t fix the problem with the driver, or there is no driver with a yellow triangle? In that case, you’ll have to use third-party software to locate and uninstall the incompatible or corrupt driver.

2. Find and Uninstall Incompatible Drivers

If you cannot locate the incompatible driver in Device Manager, use a third-party program, such as Autoruns, to identify corrupt or incompatible drivers and uninstall them.

You can follow these steps to do that:

  1. Download Autoruns from the Microsoft website.
  2. Unzip the compressed file.
  3. To run the app as an administrator, right-click on its executable file and select Run as administrator.
  4. Go to the Drivers tab.
  5. The drivers with issues will be highlighted, so locate them.
    Clicking on the Run as Administrator Option by Right-clicking on the Autoruns Executable File in Windows File Explorer

  6. Once they have been located, uncheck the box to disable them.
    Unchecking the Box for the Incompatible Driver in the Drivers Tab of Autoruns App

  7. If any driver gives an error when disabling, right-click it and select Delete.
  8. Install the latest drivers from the official website or reboot your device to let Windows install them automatically.

If you can’t locate drivers identified as incompatible by Memory integrity before, the Autoruns app will facilitate finding and removing them.

3. Uninstall Relevant Apps

If uninstalling the incompatible drivers does not work, you should uninstall the apps or software you installed from the same manufacturer as the drivers. Follow these steps to do that:

  1. Right-click on the Windows Start button and select Apps and Features.
    Clicking on the Apps and Features by Right-clicking on the Windows Start Button

  2. In the list of installed apps, locate the software from the same manufacturer.
  3. Upon finding them, click on the three vertical dots next to them and select Uninstall.

Uninstalling the relevant apps from the same manufacturer should resolve the issue. If it does not, ensure it isn’t a Windows Update issue.

If incompatible or corrupt drivers aren’t the problem, you should ensure your system is up-to-date and no updates are pending. To do this, right-click on the Windows Start button and select Settings. Next, navigate to Windows Update and click the Check for updates button on the right.

Check for Updates Windows

If they are paused, click Resume updates to let Windows update your system.

Moreover, if you’ve encountered a problem after installing an update recently, you should uninstall it. Our guide on uninstalling updates in Windows 10 and 11 explains how to do it. If pending or recently installed updates are not to blame, apply the next fix.

5. Fix Corrupt System Files

Corrupt system files are also a major cause of unforeseen issues with Windows features. The Memory integrity feature may have stopped working after a virus invaded your device and corrupted your system files. Thus, you must ensure that your system files are intact to rule out this possibility. An SFC scan can be helpful in this case.

Search for “Command Prompt” in Windows Search, right-click on the Command Prompt in search results and click Run as administrator. Then type “SFC /scannow” and press Enter.

The System File Checker command

Once the scan is complete, refer to our guide on repairing corrupt system files with Windows built-in tools so you can properly analyze the results.

Turn On the Memory Integrity Feature Again

Memory integrity is a critical security feature, and if it is not enabled, it can seriously compromise the security of your device. Hopefully, by applying the fixes mentioned in the article, you will solve the problem and easily turn on Memory Integrity.
