No worries. I forgot to mention that this will be fixed in a future
driver release, either by dual-signing the binaries with both SHA-1
and SHA-2 or only SHA-1. Requiring the Windows hotfix is a workaround
until then.

It is the same issue though, I have checked the timestamp in your BSOD
screenshot. The driver running on the system at the time of crash was
a build targeted at Win8 or newer.

Can you feed only the Win7 subset of the ISO to WDS? Sorry, I am not
familiar with WDS enough to be more helpful.

The problem with all the virtio-win releases so far is that the
drivers don't declare the minimum Windows version they support. So
Windows (or in this case WDS?) is free to choose any of them, usually
going after the highest version which tends to be the Win8 variety.
This will also be fixed soon.

What does it say when you click "Show details"?
