You're comparing a MacBook Air to a Macbook Pro Retina which use different hardware and asking why one doesn't appear to have an issue and another one does which somehow suggests new rMBP have a hardware problem.

Windows is completely irrelevant but it does receive different updates for and from various hardware/software vendors. Intel chips, GFX Cards and various other parts via Windows Update.
