How to Enable Core Isolation Memory Integrity in Windows 11

This guide explains how to turn the Core Isolation Memory Integrity feature on or off using Microsoft Security in Windows 11.

Why use Core Isolation?

Core Isolation is a security tool. It guards the most important parts of your computer against harmful software like ransomware. It works with Memory Integrity. Think of this as a locked booth for your security settings. It makes it very hard for hackers to sneak bad code onto your system. Memory Integrity uses hardware virtualization to keep these processes safe.

What happens when done?

Once you turn this on, your computer creates a virtual, private area for its main processes. This makes it much harder for attackers to mess with your system’s security.

This security feature acts like a locked booth. It stops attackers from changing your system’s defenses against threats like ransomware.

1. In the search box on your taskbar, type Windows Security and select Windows Security from the list.

2. Inside the Windows Security window, click on Device security.
3. On the next page, click the link labeled Core isolation details.

4. Toggle the Memory integrity switch to On or Off. Note: This step requires admin privileges.

If the feature will not turn on, you likely have an old or broken device driver. Check your computer maker’s website for updates to fix these problems.
