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 that guards the most important parts of your computer against harmful software like ransomware. It works with a feature called Memory Integrity, which acts like a locked booth for your security settings. This makes it very hard for hackers to sneak malicious code onto your system through low-level drivers. Memory Integrity uses hardware virtualization to keep these processes safe.

What happens when done? Once enabled, your computer creates a virtual, isolated area for its core processes. This makes it much harder for attackers to interfere with your system’s security guards.

3. On the next page, click the link labeled Core isolation details.
