Any computer without IOMMUs will not have VBS or memory integrity protection.Īll drivers on the system must be compatible with virtualization-based protection of code integrity otherwise, your system may fail. If you select Secure Boot with DMA, memory integrity and the other VBS features will only be turned on for computers that support DMA. A computer without IOMMUs will simply have Secure Boot enabled. A computer with input/output memory management units (IOMMUs) will have Secure Boot with DMA protection.

This option provides Secure Boot with as much protection as is supported by a given computer's hardware. In most situations, we recommend that you choose Secure Boot. These keys provide exactly the same set of configuration options provided by Group Policy.Īmong the commands that follow, you can choose settings for Secure Boot and Secure Boot with DMA. Set the following registry keys to enable memory integrity. Use registry keys to enable memory integrity To apply the new policy on a domain-joined computer, either restart or run gpupdate /force in an elevated command prompt. Once enabled with UEFI lock, you must have access to the UEFI BIOS menu to turn off Secure Boot if you want to turn off memory integrity. Only select Enabled with UEFI lock if you want to prevent memory integrity from being disabled remotely or by policy update. Select Enabled and under Virtualization Based Protection of Code Integrity, select Enabled without UEFI lock. Navigate to Computer Configuration > Administrative Templates > System > Device Guard.ĭouble-click Turn on Virtualization Based Security. Use Group Policy Editor (gpedit.msc) to either edit an existing GPO or create a new one. Enable memory integrity using Group Policy You can configure these settings by using the settings catalog.

Memory integrity can be turned on in Windows Security settings and found at Windows Security > Device security > Core isolation details > Memory integrity.

Microsoft Intune (or another MDM provider).

To enable memory integrity on Windows devices with supporting hardware throughout an enterprise, use any of these options:

Protects the kernel mode code integrity process that ensures that other trusted kernel processes have a valid certificate.

Protects modification of the Control Flow Guard (CFG) bitmap for kernel mode drivers.

Device Guard is no longer used except to locate memory integrity and VBS settings in Group Policy or the Windows registry.

Memory integrity is sometimes referred to as hypervisor-protected code integrity (HVCI) or hypervisor enforced code integrity, and was originally released as part of Device Guard.
