How to Turn Off Core Isolation Windows 11: A Step-by-Step Guide

Turning off core isolation in Windows 11 is a straightforward process that involves a few simple steps in the system settings. By following this guide, you’ll be able to disable core isolation, which is a security feature that protects your computer against malware. Be aware that turning it off can make your system vulnerable, so make sure you know what you’re doing and why you’re doing it.

Step by Step Tutorial to Turn Off Core Isolation in Windows 11

Before we dive into the steps, let’s understand what we’re about to do. Core isolation is a feature that uses hardware virtualization to create a secure area of system memory that’s isolated from the normal operating system. Turning it off could potentially expose your system to security risks. Here’s how to do it:

Step 1: Open Windows Security

Open the Windows Security app by clicking on the shield icon in the taskbar or searching for it in the start menu.

The Windows Security app is the central hub for all security-related settings on your system. Make sure to proceed with caution and double-check that you really want to turn core isolation off.

Step 2: Click on Device Security

In the Windows Security app, click on the "Device Security" section.

This section contains settings related to the physical security of your device, including core isolation.

Step 3: Click on Core Isolation Details

Under the "Device Security" section, find and click on "Core Isolation Details."

This will open a new page where you can manage the settings for core isolation.

Step 4: Turn Off Memory Integrity

On the Core Isolation page, toggle the switch under "Memory Integrity" to Off.

By turning off memory integrity, you’re disabling the main component of core isolation that helps protect against attacks on system memory.

After completing these steps, core isolation will be turned off. Your system might require a restart to apply the changes fully.
