My brother across the country, and I, have been dealing with his inadequate computer knowledge for over two years now. He is 67, now, and due to no fault of his he is basically illiterate computer-wise. Anyways, he effed up something a day,or so, ago and I elected to do a system restore to bring him back three days. How long is this expected to take? Ballpark for an AMD dual core laptop, two years old. Thanks!
