Hello,
Thank you for the catch and the good questions.
We need answers from Microsoft, Intel and NVIDIA.
Please see below

I think there is a signing procedure here:
https://learn.microsoft.com/en-us/windows-hardware/drivers/install/whql-release-signature
Unfortunately, after 7 years since first introduction of Windows support,
the roadmap still mentions "inbox kernel-mode driver" in "Future (unscheduled)".

Anyone from Microsoft can answer please?

We really need to state who is responsible in Microsoft.
> 4. Whether NetUIO supports Intel XL710/E810 and other PCI device IDs in a signed package.
The question refers to i40e and ice drivers support on Windows.
Someone from Intel to answer please?
> 5. Whether virt2phys is still required for mlx5 with WinOF-2,
It is said "required by hardware PMDs" but I am not sure it is true with IOVA-as-VA.
We should explain this clearly in
https://doc.dpdk.org/guides/windows_gsg/run_apps.html#install-drivers
> or whether IOVA-as-VA is officially supported in production.
It is not said it is officially supported, but I suppose it should work.
Someone from NVIDIA to confirm please?
> 6. Whether the packages support Secure Boot and HVCI / Windows Memory Integrity.
> 7. Whether redistribution with a commercial application is permitted.
> 8. Whether the obsolete dpdkwin@microsoft.com address can be removed or replaced in the dpdk-kmods documentation.
We need Microsoft support for these questions.
