I had been using the PC line up of Windows for quite a long time, marking the good old days of 2003 when I first bought my PC. Windows had been my top-notch choice for OS from then. However, nothing had made me as disappointed as my upgrade to windows 10, not even Vista or the lack of a start menu on 8. I'm currently using HP pavillion 15 laptop model. I upgraded a few days back from windows 7. Mine was a 32-bit one and my first disappointment was that the upgrade tool also upgraded mine to Win 10 32-bit, where it SHOULD have let me choose what architecture I prefer. Anyway, I had to take a full day off and download it again (the 64-bit because that's what I needed) and from then, my laptop crashes everytime I put it to sleep by closing the screen panel lid. Sometimes, it even crashes when I press the shut down button. And the updates! Oh Good Lord! This is something I must say out loud to MS. The point that you made the upgrade free, well, I was ready to pay for it. But when the updates started to kuck in, I started to regret my decision on upgrading. MS shouldn't be the one to bother me wuth updates after updates! I could be doing important stuff. Why do I have to close my important tasks just to apply those stupid updates??? I will update when I want to update, i.e., when my work is over! REALLY DISAPPOINTING MICROSOFT! This even makes 8 more pleasing to use to me. Personally, I regret my move to Win 10 and I think it was one of the worst decisions I ever made.
