Disable Core Isolation

Core Isolation is a security feature in Windows 10 and Windows 11 that uses virtualization-based security to protect core processes from malicious software. However, you may need to disable Core Isolation for compatibility reasons with certain applications or drivers.

1. Open Windows Security

   • Click the Start button or press the Windows key on your keyboard.
   • Type Windows Security in the search bar and select the Windows Security app from the search results.
2. Navigate to Device Security

   • In the Windows Security app, click on Device security in the left-hand menu.
   • Under the Core isolation section, click on Core isolation details.
3. Disable Memory Integrity

   • In the Core isolation details window, you will see an option for Memory integrity. Toggle the switch to Off.
4. Restart Device

   • Click the Start button, select the Power icon, and choose Restart.

Troubleshooting

If the Memory integrity toggle is grayed out or you encounter issues disabling Core Isolation, you may need to take additional steps.

Verify Driver Compatibility

1. Check for Incompatible Drivers

   • Some drivers might prevent you from disabling Memory integrity. Check the list of incompatible drivers by running the following command in Command Prompt:
   sigverif
   

2. Update or Remove Incompatible Drivers

   • Update the drivers from the manufacturer’s website or, if necessary, uninstall the incompatible drivers through Device Manager.

Edit Registry (Advanced)

Editing the registry can have serious consequences if not done correctly. Proceed with caution and consider backing up the registry first.

1. Open Registry Editor

   • Press Windows + R, type regedit, and press Enter.

2. Navigate to the Core Isolation Key

   • Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity.

3. Modify the Value

   • Double-click the Enabled entry and change its value to 0.

4. Restart Your Computer

   • Restart your computer to apply the changes.
