How to Disable HVCI and KMCi in Windows 11: A Step-by-Step Guide

Disabling HVCI and KMC in Windows 11 is a straightforward process that starts with accessing the Windows Security app. From there, you’ll need to navigate through Device Security settings and turn off Core Isolation. This guide will walk you through each step with simple explanations to ensure you can complete the task without any confusion.

How to Disable HVCI and KMC in Windows 11

Turning off Hypervisor-protected Code Integrity (HVCI) and Kernel-mode Code Integrity (KMC) will help you manage device security settings more effectively. Follow the steps below to disable these features.

Step 1: Open Windows Security

First, click on the Start menu and type "Windows Security." Then, hit Enter.

Windows Security is your hub for managing various security settings on your device. Accessing it will allow you to make necessary changes to HVCI and KMC settings.

Step 2: Navigate to Device Security

Once you’re in the Windows Security app, find and click on the “Device Security” tab.

Device Security contains all the settings related to the hardware security of your device. This is where you will find the Core Isolation settings.

Step 3: Click on Core Isolation Details

Within the Device Security section, locate the “Core Isolation” area and click on the “Core Isolation Details” link.

Core Isolation protects important parts of the Windows kernel, but disabling it is necessary for turning off HVCI and KMC.

Step 4: Turn Off Memory Integrity

In the Core Isolation Details window, you’ll see an option labeled “Memory Integrity.” Toggle this switch to the off position.

Turning off Memory Integrity will effectively disable HVCI and KMC, but keep in mind this might lower your device’s security.

After completing these steps, HVCI and KMC will be disabled, which might help with compatibility issues or system performance. However, this also reduces some security measures.
