I don't see the point in that - i had some computers receiving 1709 as upgrade from a previous version (160x, and 1703) and other computers, that were completely fresh installed from 1709 iso - same bug.
Anyway.. on a computer that's not needed that much right now, i wanted to run the repair upgrade with the latest windows 10 1709 x64 iso: now, windows can't mount the image.. somwhat like 'problems to make the file available'. i'm running the german of windows where it says "Problem beim Bereitstellen der Datei", suggested fixes like removing virtual dvd drives don't work: no (hidden) virtual dvd drives.. now writing the image to an usb stick.. I'll report back tomorrow..
