❌Disable Core Isolation

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.

Disabling Core Isolation can reduce the security of your system. Only disable it if absolutely necessary.

​Step 1: Open Windows Security

1. Open the Start Menu

   • Click the Start button or press the Windows key on your keyboard.

2. Search for Windows Security

   • Type Windows Security in the search bar and select the Windows Security app from the search results.

​Step 2: Navigate to Device Security

1. Open Device Security

   • In the Windows Security app, click on Device security in the left-hand menu.

2. Core Isolation Details

   • Under the Core isolation section, click on Core isolation details.

​Step 3: Disable Memory Integrity

1. Toggle Memory Integrity Off

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

You might need to restart your computer for the changes to take effect. Save any open work before proceeding.

​Step 4: Restart Your Computer

1. Restart

   • 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

   sigverif

2. Update or Remove Incompatible Drivers

   • 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.
