- Unfortunately, HVIC and VBS are only available on systems running 64-bit versions of Windows 10 (and eventually Windows 11). Those of you running 32-bit systems will have to upgrade your software and possibly your hardware to access these core isolation security features. These features also require an updated input-output memory management unit.

Microsoft offers regular updates to Windows 11, so support for previous releases is time limited. Where possible, always make sure that you update to the most recent Windows release, which still offers Microsoft's full support. Currently, McAfee products are not supported on Windows 11 S.

Nov 19, 2022 · Windows 10 HVCI mode is the same exact Hypervisor-protected Code Integrity - virtualization-based security (VBS) feature in either Windows 10 or 11, it's simply the fact that McAfee in some cases can't tell the difference, so it indicates Windows 10 because it's not aware it's actually Windows 11.

is a virtualization-based security (VBS) feature available in Windows. Memory integrity and VBS improve the threat model of Windows and provide stronger protections against malware trying to exploit the Windows kernel. VBS uses the Windows hypervisor to create an isolated virtual environment that becomes the root of trust of the OS that assumes the kernel can be compromised. Memory integrity is a critical component that protects and hardens Windows by running kernel mode code integrity within the isolated virtual environment of VBS. Memory integrity also restricts kernel memory allocations that could be used to compromise the system.
Memory integrity works better with Intel Kabylake and higher processors with
, and AMD Zen 2 and higher processors with
capabilities. Older processors rely on an emulation of these features, called
Protects modification of the Control Flow Guard (CFG) bitmap for kernel mode drivers.
Protects the kernel mode code integrity process that ensures that other trusted kernel processes have a valid certificate.
To enable memory integrity on Windows devices with supporting hardware throughout an enterprise, use any of these options:
Microsoft Intune (or another MDM provider)
can be turned on in

Beginning with Windows 11 22H2,
If a device driver fails to load or crashes at runtime, you may be able to update the driver using
If you experience a critical error during boot or your system is unstable after turning on memory integrity, you can recover using the Windows Recovery Environment (Windows RE).
First, disable any policies that are used to enable VBS and memory integrity, for example Group Policy.
Then, boot to Windows RE on the affected computer, see
After logging in to Windows RE, set the memory integrity registry key to off:
reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity" /v "Enabled" /t REG_DWORD /d 0 /f
Memory integrity can protect a Hyper-V virtual machine, just as it would a physical machine. The steps to enable memory integrity are the same from within the virtual machine.
Memory integrity protects against malware running in the guest virtual machine. It doesn't provide extra protection from the host administrator. From the host, you can disable memory integrity for a virtual machine:
Set-VMSecurity -VMName -VirtualizationBasedSecurityOptOut $true
Requirements for running memory integrity in Hyper-V virtual machines
The Hyper-V host must run at least Windows Server 2016 or Windows 10 version 1607.
The Hyper-V virtual machine must be Generation 2, and running at least Windows Server 2016 or Windows 10.

Sep 20, 2022 · Hypervisor-protected code integrity (HVCI), also called memory integrity, will be enabled by default on all new Windows 11 devices. HVCI uses VBS to run kernel mode code integrity (KMCI) inside the secure VBS environment instead of the main Windows kernel.
