It's such a shame. It's almost as if Microsoft planned their own demise as the OS-supplier of choice for non-Mac people.
Vista Ultimate was, in my opinion, the last great OS. Pity one couldn't just settle for an OS and keep it forever....safely.
I upgraded mine to 7 Ultimate and regretted it, however, it's easy to carry forward Vista features to that OS. Above that it gets harder and harder.
I'd settle for 10 over 8.1 any day but why they made it so plain and drab looking and so unfriendly (as in Windows Updates and many other settings) only they know.
