OS is just A PART of the whole PC HW/SW architecture, MS doesn't own the whole platform, it just provides one of the many possible OS' just like AMD, Intel and NVidia provide some of the possible families of CPUs and GPUs, so it shouldn't try to monopolise it as if it owned it all. Even if it owned the whole platform, having on PC a near monopoly of the OS, serious antitrust authorities in seriously governed countries would have some objection to make to MS trying to close the app and game market.
