HVCI / Core Isolation

Memory Integrity (HVCI) can block certain drivers from loading. Here's how to turn it off — and back on when you're finished.

Disable Memory Integrity

• Open Windows Security
• Go to Device Security
• Open Core Isolation Details
• Disable Memory Integrity
• Restart your PC

Registry method

In Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard and set EnableVirtualizationBasedSecurity = 0.

Then go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity and set Enabled = 0. Restart your PC.

Disable Hypervisor

Open Command Prompt as Administrator and run: bcdedit /set hypervisorlaunchtype off — then restart your PC.

Verify status

Press Windows + R, type msinfo32, press Enter, and confirm Virtualization-based security reads: Not Enabled.

Re-enable

Run bcdedit /set hypervisorlaunchtype auto and restart your PC.
