I have been running win 8 for a longtime, and ran win 8.1 for months without any problems, then got a virus, and could not get rid of it, so went back to win 8. Now when I try to reload win 8.1 it says "failure configuring windows updates, and reverts to win 8. What can I do ? or is it possible to load win 10 with what I have now. ????
