I just spent $550. to have the old Windows removed, reinstalled Windows 7 again because I do not want Windows 10. He installed all the latest updates in everything, he worked his butt off and even Microsoft was on with 2 hours with him and they said they could not fix the problem. They had no idea what to do except remove the the corrupt windows 7 and replace it with a clean windows 7....that is what he did. Now I am hoping the new mouse makes the difference. I must go now.
