Unfortunately Microsoft has not made it very easy to update. You have to make a bunch of Registry edits, and never got around to trying that out. I have a SSD in my system, but not my C drive yet. I would not buy a ew computer without a SSD. That is why Android and i OS systems are enjoyable to use since they use SSDs rather than mechanical HDs. There is so much conflicting information out there on changing over to a SSD, that it is frustrating trying to see what may apply in your case. Will stick with W7 though. There is no W8s in my future at least anytime soon.I wouldn't want to install it on any of my computers even if it was free.
