I believe this is the key, clearly there is a difference between various ISOs, despite how illogical it may seem.For me the driver worked right away on my windows 10 install, as long as I selected the "lowest" folder, so either the amd64/w10 or the vioscsi/w10/amd64
The one thing I did see in other posts, that some windows-iso's of different languages behave differently from eachother, but the english version usually works fine.
