    Intel wouldn't care about customers, they'd have a ton of worthless inventory because it couldn't run newest windows any more. But I'm certain that MS wouldn't do that
    either, because of the support nightmare caused by Intels ISA segmentation, and there are still surprisingly many people running sandybridge/early bulldozer era machines.
