Recovering from HVCI Boot Loop After Enabling Memory Integrity

Hi Hakim Ismail,

What’s happening is that Memory Integrity (HVCI) is enforcing virtualization-based protections, but the legacy debugger driver isn’t compatible, which causes the system to crash before Windows can fully load.

To recover the affected laptops, you’ll need to disable HVCI offline. The safest way is to boot into Windows Safe Mode with Command Prompt (or use Windows Recovery Environment if Safe Mode isn’t accessible). From there, you can run:

• bcdedit /set hypervisorlaunchtype off ,this disables the hypervisor so HVCI won’t load.
• Alternatively, you can edit the registry offline: navigate to HKLM\System\CurrentControlSet\Control\DeviceGuard and set EnableVirtualizationBasedSecurity to 0. Also check HKLM\System\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity and set Enabled to 0.

After making these changes, reboot normally and the system should come back without the BSOD loop. Once recovered, you can either remove the incompatible driver or keep HVCI disabled on those older models.

I hope the response provided some helpful insight. If you find this answer useful, please hit “accept answer” so I know it addressed your concern.
