I am still using the Win 7 OS. I have been very protective of it and have managed (thus far) to block efforts by MS to replace it with Win 10. My wife has a laptop running Win 10 and I have had just enough exposure to it to know I don't want it! If at some time MS manages to replace my OS with Win 10 or something else, I will probably move on to one of the Apple products. As mentioned above, Win NT was a great system, perhaps the best thing Microsoft ever produced.
