Hi,
I installed your ISO as a "Upgrade" over the Win 7 Ultimate SP1 I was running...
There was no "Repair" option...
It was successful, but it had issues... For one thing IE11 wouldn't install and I couldn't read the forum pages with IE8...
I reloaded my Image of Win 7 which is from a much older ISO I think...
That might make a difference...
This particular image did not have all cumulative updates installed...
That might make a difference also...
I will try again with all cumulative updates installed...
