Starting in Windows 11, 22H2 and Windows Server 2025, VBS and Credential Guard are enabled by default on devices that meet the requirements.
Credentials Guard needs to be turned off in order to restore guest machine using Virtual Export. Check the following Windows Registry:
Key path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard
Key name: EnableVirtualizationBasedSecurity
Type: REG_DWORD
Value: 0 (to disable Virtualization Based Security)
Virtual Standby job might fail even if the feature is not configured. Created the Windows Registry Key and set it to 0. This feature can also be enabled by Group Policy; therefore, if the job keeps failing, check the GPO settings.
Support for Credentials Guard will be provided in a future release of Rapid Recovery.
