Obviously the best version of windows for the navy and a lot of big businesses.
I would think W10 is not user friendly for some businesses or for that matter some users.
So why do they not come out with a new version of XP for those that would want to use it without all the bundled crap on it.
I can see your point of view why have a state of the art Aircraft Carrier with an ancient version of XP on it.
Maybe because it is less complicated than W10 but you have to think that the navy must know what's best for communications on board.
I would think as the new Aircraft carrier uses it all naval ships will also still use it.
