Disabling HVCI and KMC in Windows 11 is quite straightforward. These settings, known as Hypervisor-Protected Code Integrity (HVCI) and Kernel Mode Code Integrity (KMC), are part of Windows’ security measures designed to keep your system safe from malware. If you need to disable them, maybe for software compatibility reasons or troubleshooting, you can do so by tweaking some settings in the Windows Security app and using the Command Prompt. Don’t worry, we’ll walk through each step to make sure you get it right.
How to Disable HVCI and KMC in Windows 11
In this section, we’ll guide you through the process of turning off HVCI and KMC on your Windows 11 computer. Follow these easy steps to modify your system settings safely.
Step 1: Open Windows Security
First, click on the Start menu and search for "Windows Security."
Windows Security is the built-in app that protects your PC. By searching for it in the Start menu, you ensure quick access to the features you need to adjust.
Step 2: Navigate to Device Security
Next, click on "Device security" in the navigation pane.
Device Security helps you manage your PC’s hardware security. This is where you’ll find the settings related to your device’s integrity protections like HVCI and KMC.
Step 3: Select Core Isolation Details
Then, click on "Core isolation details."
Core Isolation is a feature that uses virtualization-based security. By accessing its details, you can view and tweak settings related to memory integrity, which involves HVCI.
Step 4: Disable Memory Integrity
Toggle off the switch for Memory Integrity.
Turning off this switch will disable HVCI. It might require you to restart your computer for the changes to take effect. If the switch is grayed out, administrative permissions are needed.
Step 5: Open Command Prompt
Search for "Command Prompt," right-click on it, and choose "Run as administrator."
Executing the Command Prompt as an administrator ensures that you have the necessary permissions to make system-level changes, like disabling KMC.
Step 6: Enter the Command to Disable KMC
Type bcdedit /set nointegritychecks on and press Enter.
This command stops Windows from enforcing KMC, effectively disabling it. Ensure you type the command accurately to avoid any errors.
After executing these steps, HVCI and KMC will be turned off on your Windows 11 machine. This change should allow software that previously encountered compatibility issues to run without problems.
Tips for Disabling HVCI and KMC in Windows 11
- Always back up your data before making system changes.
- Use an administrator account to ensure you have the necessary permissions.
- Disabling these features may increase security risks; weigh the pros and cons.
- Restart your computer after making these changes to ensure they take effect.
