The times I work this I find I have to manually update IE and other items till it works. I do not have a hard copy of what I've done so far but as you are installing W7 a lot you have to try manually installing missing updates. Try BELARC ADVISOR to get a list.
for about the last month or so (since the "FREE" win10 crap ended) there seems to be an issue with updating a fresh install of Win7. It occurs on EVERY machine ive reloaded. I was able to get around it for about a week now it seems to have stopped completely ? They geniuses at Microcrap have also removed / "retired" ALL the fixits. and whats left does nothing but the same "searching for windows updates" that never completes. Is anyone else experiencing this issue ? Does anyone know of a fix or is it unfixable as they seem to have but a HUGE restriction on dl bandwidth for the updates to the point where it will take forever (and by forever I mean maybe a week or longer) to actually dl the updates. I have yet to have it finish the first set of updates on 3 machines now.
