No, because I don't do the updates unless there is a need, and in the 18 or so months since I built my rigs, there hasn't been a need, and I am quite happy with W7 Pro, no intention of moving further until it is absolutely necessary due to software or hardware support etc.
Having said that, on one of my laptops which I use for the net, which i do update from time to time, I did get the feeling of a possible slow down since I last updated, which contained the Windows 10 thingy, nothing drastic, but I did think it wasn't quite as snappy, no more updates for me.
