From 98 to Win 8.1 I had all versions, always up to date. When Vista came I was disappointed for the first time, but Win 7 then has compensated me. But what Win 8 or 8.1, brings to me is just junk. Am therefore again went on Win 7 back. I would recommend anyone to wait on Win 10 and not Win 8 / 8.1 purchase.
Otherwise, even Linux would recommend always better than Win 8
