I installed Windows 10 Pro a week ago over Windows 7 Pro and I have to say generally I like it. They had disabled so many things on Windows 7 like Movie Maker and now I can use it again plus it has a decent photo editor. As well as Trainz I play Fallout 76 and the first day and a half gameplay was as smooth as butter but then for one day it descended into crashes and freezes which made both games virtually unplayable. Then suddenly, presumably due to an update , it righted itself and it is now 100% stable.
