Disable hardware acceleration for Office in Application Guard

This policy setting controls whether Office in Application Guard uses hardware or software acceleration to render graphics. If you enable this setting, Application Guard uses software-based (CPU) rendering and won’t load any third-party graphics drivers or interact with any connected graphics hardware. Important: Be aware that disabling or not configuring this policy setting with potentially compromised graphics devices or drivers might pose a risk to the user's device. If you disable or don't configure this setting, Application Guard uses Hyper-V to access supported, high-security rendering graphics hardware (GPUs). These GPUs improve rendering performance and battery life while using Application Guard, particularly for video playback and other graphics-intensive operations. If you disable or don't configure this setting without connecting any high-security rendering graphics hardware, Application Guard will automatically revert to software-based (CPU) rendering. Note: This policy setting only applies to Microsoft 365 Apps for enterprise.
