I upgraded to Win 10 and have had nothing but problems for the last month. Apparently it run's fine on brand new latest computers. Problem is older computers not designed to run it (but Microsoft say will)
I was given a desk top with windows 7 which I intended to use to play films on the TV. However although on boot TV started to work as it continued lost signal to TV it would only work with a monitor which was far smaller than TV so not really what I wanted. However it asked me to do updates and in error I ended up installing windows 10.
However once installed TV worked A1. So as far I am concerned windows 10 is 100% better as windows 7 did not do what I wanted.
