I ended up going back to a 1703 Macrium backup, loading that. Catching up on updates ( itunes, Cumulatives etc) and then making a new backup. The hit windows update. It loaded 16241 which was interesting and took 1 hr ++ Then after a couple of reboots I hit WU again and down comes 16251. Which is now in the 'working on updates' phase so it will probably work. Probably be a bit over 1.5 hours when it is finished. It was 1 hr 45 minutes.
I wonder why each update gets longer...I bet they have some kind of bug in there. Something like, for every device it scans the whole catalog of devices. For every app the same.
One interesting thing in the update was being able to link ones phone with W10...problem is that the iPhone link is not done yet. I couldn't find anything else interesting to me in there.
