How to fix Memory Integrity turning off again by itself

Troubleshooting Guide: Resolving Automatic Deactivation of Windows 11 Memory Integrity

Introduction

Enabling Memory Integrity—a key security feature in Windows 11—helps protect your system by safeguarding it against certain types of malware and unauthorized modifications. However, some users encounter issues where Memory Integrity turns off automatically after enabling it, preventing the feature from staying active. This guide provides step-by-step troubleshooting techniques to help you resolve such issues effectively.

Understanding the Issue

Many users report that after enabling Memory Integrity through Windows Security, the system prompts for a restart. Yet, upon reboot, Memory Integrity is disabled automatically. Common causes include incompatible drivers, BIOS settings, or system conflicts. Identifying and resolving these underlying issues is essential to maintain a secure, stable environment.

Step 1: Verify BIOS and Virtualization Settings

• Enable Virtualization in BIOS:

  1. Restart your PC and enter BIOS/UEFI settings (usually by pressing F2, F10, DEL, or ESC during startup).

  2. Locate settings related to virtualization technology (Intel VT-x, AMD-V, etc.).

  3. Ensure virtualization is enabled.

  4. Save changes and exit.

• Confirm BIOS is up to date, as outdated firmware can interfere with features like Memory Integrity.

Step 2: Identify and Remove Incompatible Drivers

Memory Integrity relies on drivers that support Core Isolation. To locate incompatible drivers:

1. Open Windows Security:

   • Navigate to Settings > Privacy & Security > Windows Security.

   • Click on ‘Device Security’ > ‘Core isolation details.’

2. Check for incompatible drivers:

   • Windows may list drivers preventing Memory Integrity from staying enabled.

3. Use PowerShell to list third-party drivers:

   powershell
driverquery /v /fo list

4. Update or uninstall drivers identified as incompatible:

   • Visit the manufacturer’s website to download the latest drivers.

   • Use Device Manager to uninstall problematic drivers, then reinstall updated versions.

Step 3: Use the Compatibility Mode for Drivers

Some drivers are incompatible with Memory Integrity. If updating doesn’t resolve the issue:

• Consider replacing third-party drivers with Microsoft-provided alternatives.

• For essential drivers that are incompatible, contact the hardware manufacturer for guidance.

Step 4: Ensure Windows is Fully Up to Date

• Keep Windows 11 updated:

  • Go to Settings > Windows Update.

  • Check for updates and install all available patches.

• Updated OS versions often include
