If MS had continued to support XP, I'd have been more than happy to stick with it. However, my old PC was creaking and the new one I bought last year came with 8.1, which was an improvement on 8, but still a bit clunky.

Win 10 seems less clunky than 8.1. If I hadn't been driven out of my mind by lumbering daily 8.1 updates which didn't, (update, that is) and which kept requiring seemingly constant re-starts, I would probably have stayed with 8.1 but, having 'upgraded' to 10, I have no regrets so far. Whether that will continue to be the case, only time will tell but, as yet, I haven't been afflicted with any of the problems others have reported here.
