I have the same problem only with version 1709 failing to load on a Surface Pro 4 (which is a MS product). It continually fails to install due to driver error. I believe the issue is that Windows 10, 1703 and `1709 have come to the point where there
are just too many variables for MS to make new windows version that can update without a clean install. Meaning, they are at the point where it is impossible to handle all the loaded software and drivers on every person's different type of computer including
MS's own hardware. So updating is only a 80% possibility. Clean installing is a pain for those of us who do run numerous programs and of course even MS office will think you are on a different computer when you do a clean install, so you better have your
product keys handy. I managed to hold it at bay by using group edit.. But every so often I try using the MS update assistant. When I recently updated the update assistant, it appears they've turned it into somewhat of a virus in that you can't unistall
it. It comes back and back and back. Task scheduler won't kill it. I'll try a few more things and then I may have to bite the bullet and do a clean install. The message here is don't use update assistant. If you already have, it's probably too late.
Fortunately, my main computer is an Apple running Boot Camp and Parallels. I have been successful holding off 1709 through the group edit and I have not and won't run update assistant. If you think 1703 was tricky to update, wait until you try 1709.
