Windows 10: Boot DMA Protection not supported

My hardware meets all requirements of Kernel DMA Protection, but i just can't enable it. I already turned on CPU Virtualization, IOMMU and TPM 2.0. Looking at Windows Admin Center, it says that:My PC Specs:CPU: Ryzen 7 5800xMotherboard: B550M AORUS Elite GigabyteBIOS Version: FE Mar 27, 2024RAM: 128GB DDR4 3600MHzDisk: NVMe Corsair MP600 CORE XTGPU: GTX 1060 6GB

how to enable kernel dma protection

Good day! I am Independent Advisor Paul R. and also a Microsoft/Windows user like you and I am glad to be able to provide assistance to you today. I understand that you are looking to enable the Kernel DMA protection.

Windows 10 home does not exactly support the Hyper-V role/feature in which it can deter with this feature that you are looking to use but if you still want to check your system then you can check the steps below and hopefully this helps out with your query.

- Open the Run window and type msinfo32 and press Enter

- This should open the System Info window, check and find the Kernel DMA Protection option in the list and check if it’s on or off

- If it is on it means that your System is protected from drive by DMA attacks

- If it is off and Virtualization Enabled in Firmware has yes then it means your System does not support the protection feature

- In the event that the feature is off and the Virtualization Enabled in Firmware has no then your System supports the protection feature

Paul R.
