I had some worries about Win 10 but found out much later that my Win 7 ultimate was a fake so upgraded to windows 10 last year and it will load and shut down very quickly, nothing like the long wait for 7 ultimate.
I really don't see any difference other than an improved operating system that also can be linked to my cell phone apps (still learning), windows Vista was hands down the worst operating system but that's what I got when I bought my first laptop it was always a slow start and slow shut down and it seemed to drag the processor down, I'm not a computer/software expert so take my comments with a grain of salt.
Only thing that I needed to do after upgrading to Win 10 was update the Java, flash players, my video card. It's basically the same only a little different in finding the settings but there's several ways to go about that, both my desk tops have Win 10 now. Video calls on skype or Facebook are flawless I have the A4tech web cam, even playing games online they work, the tech will claim that most of the free video games he gives you won't work but they do and there's a work around if they don't and Youtube will walk you through that.
Improvement reminds me of what it's like getting a new smart phone, what a difference in connectability and ease of apps and programs, I am not feeling any downsides even my son told me to upgrade our other desk top so I did about 3 months ago, last note I still can download music. movies from Youtube or other spots on the internet.
