I run with Windows 10 and my wife still uses windows 7. We are both happy campers, but I would not change from 7 if my computer had come with it. As it is, my computer came with 10 and since then I have disabled all the communications that it wants to do on a regular basis. Not sure if I have the first version but it is an earlier version. Works ok for me, but then I don't usually go for new programming, play games etc. I just type some letters, and surf some,watch some youtube... simple stuff,,,now have no problems,,,, yet.
