I personally have wasted enough time not to think of getting another PC with a MS operating system. Since the upgrade of my Win 8.0 to 8.1, I have had problems with every patch Tuesday. I have spent with level 1 and 2 MS support close to 10 hours, plus all the time I spent DISM this, DISM that.
i will spend a final weekend to do factory refresh, apply all the updates, e-bay the Lenovo ultrabook, and get a Mac!
