I don't think stock would be a good metric. If I had to guess, Windows at this point is probably just a cost center. Their main revenue streams are office362 and azure. The Windows OS itself is just a rounding error. Another way to put it. People aren't buying Microsoft stock because of Windows. They are buying because of Azure and Office365.
