My update went smoothly, but my pc spent a day on ASRock's Xtreme Tuner where it was reading -60C for my MB temperature! After a day and a couple restarts it's back to normal. I can only attribute this weird behavior to the update. No complaints now though. Question: The article said there were only five weeks left to get this update before future patches won't work. what if someone buys Windows 8.1 4 weeks from now, then installs two weeks later? Are they barred from being patched? I really didn't understand what the guy meant.
