Memory Integrity is an important Core Isolation security feature of Windows 11 that helps protect your system from malware and other threats. If this feature is off, it can be a threat to the security of your system. In this article, we will explain in detail how to enable Memory Integrity, as well as provide solutions to problems related to it.

What is Memory Integrity?

Memory Integrity, also known as Hypervisor-protected Code Integrity (HVCI), is a part of Windows 11’s Core Isolation technology. This feature checks the code running on your device in a virtual environment and prevents any unauthorized or bad code from entering the system.

Why does Memory Integrity get disabled?

There can be several possible reasons behind Memory Integrity being off:

Outdated or incompatible drivers

The virtualization setting is being disabled

Some important settings are off in BIOS

Conflict of third-party antivirus or security software

How to enable Memory Integrity in Windows 11

1. Enable via Windows Security Settings

1. Click on the Start Menu and open Windows Security.

2. Go to the Device Security section.

3. Here you will see Core Isolation, click on it.

4. Turn on the Memory Integrity toggle.

5. Restart the system.

2. Enabling from Windows Registry (for advanced users)

> Note: It is important to take a backup before making changes to the Registry.

1. Type `regedit` in the Run Box and press Enter.

2. Go to the following path:

`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity`

3. There should be a DWORD value named `Enabled`.

If not, create New > DWORD (32-bit) Value and name it `Enabled`

Double click it and set its value to `1`.

4. Reboot the system.

What to do if Toggle is not Enabled

1. Check for Incompatible Drivers

1. Go to Windows Security > Device Security > Core Isolation.

2. Scroll down, and you may see a list of Incompatible Drivers.

3. Note down the driver name and download its latest version from the manufacturer’s website.

Example:

If a driver `IntcRun.sys` is causing the problem, install the latest version from Intel’s site.

2. Enable Virtualization in BIOS

Virtualization needs to be enabled for memory integrity.

1. Restart the system and enter the BIOS (usually with the F2, DEL or Esc key).

2. Enable Intel VT-x or AMD-V.

3. Save the settings and reboot the system.

3. Check through the Group Policy Editor

Problem: Error is coming as soon as you click on Enable

Solution:

Check Driver Compatibility

Ensure Virtualization in BIOS

Download all patches from Windows Update

Problem: The System starts running slowly after enabling

Memory Integrity can affect performance in some older systems.

If you have an SSD and 8 GB+ RAM, then the difference will be less.

Otherwise, you should turn it off and use alternative security measures.

Benefits of Memory Integrity

Better protection from Zero-Day attacks

Protection from driver-based attacks

Benefits of Hardware-Level Virtualization

Better Integration with Windows Defender

Under what circumstances should Memory Integrity be kept off

If your system has old or essential hardware drivers that cannot be updated.

If your PC is low-end and the performance impact is high.

> However, for security reasons, we always recommend keeping it enabled.
