Anniversary Upgrade? Yes, it downloaded (automatiaclly, thanks, Microsoft), but proceeded to foul the whole system up. I managed to roll back, after a fashion, but it screwed up the whole net. Every website was httpS, with a warning that the security certificate was invalid, and I couldn't access it. Money to a professional, who managed to sort that out, but I still don't like Win 10. Win 8.1 I liked, and it wasn't until I spent a couple of computerless days with an old laptop that I remembered how good XP was.
