I discovered this "community" because I was looking for the answer to this question (how to leave a comment on an article if I don't have a Flakebook or Twit account). Oddly, though there seem to be a couple of MS support folks who chime in here infrequently, they haven't responded directly to the question (above). And it even seems that members of the cabal are unable to post.
As for Windows 10, it wasn't worth the trouble over 7. I've had some odd crashes, trouble with one of the updates, and inability to sort out how each of my windows devices can live together in the cloud. For a while, every time I fired up my notebook it kept trying to download all of the photos (8GB worth) that my phone and Surface Pro kept uploading to the heavenly cloud. Managed to stop that, but it really put a dent in my monthly data quota. And I somehow managed to sync all of my settings across devices, which I really didn't want to do.
It might make more sense to upgrade from 8.1 than from 7, but even then I'd be disinclined to. Windows 10 seems designed for those who were scared off 8 by the unfamiliar appearance (new start screen and lack of a start button). MS is betting on their willingness to upgrade their aging W7 machine (or XP or whatever) for something that looks more comfortable to them than W8 did. Right now, I have two XP machines, a W7 notebook, this W10 notebook, a W8.1 Surface Pro2, and a Windows Phone running 8.1. Tough to keep on top of when you're not in the computing field.
