I have now reinstalled win 10 3 times due to win updates
I didn't know you were an insider??/Never had to reinstall - started Win 10 in the Insider program, progressed through all the versions (lots and lots of updates), finally ended up with RTM and couldn't be happier.
I was - switched over to RTM about a year or so ago when I got my new computer and had to upgrade from 8.1 to 10. My biggest problem was that I had DSL and it took hours and hours to download the new releases. Now I have charter, so it would go a lot faster, but I'm happy with version 1709.I didn't know you were an insider??/
I've been on the inside since way back
