How to Fix Memory Integrity Is Off Error in Windows 11

Memory Integrity is a security feature in Windows 11 that is part of Core Isolation. It helps protect your system by preventing malicious code from accessing high-security processes in memory. When enabled, it uses virtualization-based security to isolate critical system processes from potential threats. However, some users encounter the “Memory Integrity is off” warning inside Windows Security.

This error typically appears when incompatible drivers, outdated system components, or hardware limitations prevent Memory Integrity from being enabled. Even if your system supports the feature, driver conflicts can block activation. Since Memory Integrity is an important security layer, resolving this issue helps maintain system protection and stability.

This guide explains how to fix the “Memory Integrity is off” error in Windows 11 using structured troubleshooting steps.

How to Fix Memory Integrity Is Off Error in Windows 11

If the toggle fails or shows incompatible drivers, proceed to the next step.

2. Identify and Remove Incompatible Drivers

Incompatible drivers are the most common cause of this error.

1. Open Windows Security.
2. Go to Device security.
3. Click Core isolation details.
4. Review the list of incompatible drivers displayed.
5. Note the driver file names.
6. Press Windows + X and select Device Manager.
7. Locate the related device and right-click it.
8. Select Uninstall device.
9. Restart your computer.

After removal, attempt to enable Memory Integrity again.

3. Update All Drivers

Outdated drivers may prevent Memory Integrity from functioning.

1. Press Windows + X and select Device Manager.
2. Expand key categories such as Display adapters, Network adapters, and System devices.
3. Right-click each device and select Update driver.
4. Choose Search automatically for drivers.
5. Restart your computer after updates complete.

You may also download updated drivers directly from your hardware manufacturer’s official website.

4. Enable Virtualization in BIOS

Memory Integrity requires virtualization support.

1. Restart your computer.
2. Enter BIOS or UEFI settings (commonly by pressing F2, F10, Delete, or Esc during startup).
3. Locate the Virtualization Technology or SVM Mode setting.
4. Enable virtualization.
5. Save changes and exit BIOS.
6. Boot into Windows and attempt to enable Memory Integrity again.

Virtualization must be enabled for Core Isolation features to function properly.

5. Run System File Checker (SFC)

Corrupted system files can prevent security features from activating.

1. Press Windows + S, type cmd.
2. Right-click Command Prompt and select Run as administrator.
3. Type the following command and press Enter:sfc /scannow
4. Wait for the scan to complete.
5. Restart your computer.

SFC repairs corrupted system files that may interfere with Windows Security features.

6. Run DISM to Repair System Image

If SFC does not resolve the issue, use DISM.

1. Open Command Prompt as administrator.
2. Type the following command and press Enter:DISM /Online /Cleanup-Image /RestoreHealth
3. Wait for the process to complete.
4. Restart your PC.

DISM repairs deeper system image issues affecting Core Isolation.

7. Install Pending Windows Updates

Outdated Windows builds may contain compatibility issues.

1. Press Windows + I to open Settings.
2. Click Windows Update.
3. Select Check for updates.
4. Install all available updates.
5. Restart your computer.

Keeping Windows 11 updated ensures security features work correctly.

Conclusion

The “Memory Integrity is off” error in Windows 11 is usually caused by incompatible drivers, disabled virtualization, outdated system files, or pending updates. By removing problematic drivers, updating system components, enabling virtualization in BIOS, and running system repair tools, you can successfully enable Memory Integrity.
