Windows re-install takes a lot of time. Especially if one has to then also wait for all updates (incl 1709 fall creator's update). We're talking hours there unfortunately.
I'll recommend using image with current updates. 15 minutes to reinstall with all current updates and automatic updates disabled as free bonus in my case.
Wanted to create an image of the fully working system... Unfortunately I hadn't got that far yet. Oh well. Since I don't have a spare GPU at hand (not going to take any off my working rigs just for this, that'd be asking for trouble), re-install here we come.
Also, is there anywhere I could get devcon.exe without having to download the whole Windows Drivers Kit?
