Kernel itself is not a sole determining factor. Windows 10 is a mobile operating system which can't decide if it wants to target the amateur android "click here and it will happen" users or more advanced PC users. It's trying to be two things at once. Now only that it doesn't give users the kind of control Windows 7 use to give it's users. The Settings app is a disaster. Half of the time, I can't remember if a certain tweak is in settings o in control panel and if it's in settings then exactly where. There are things fundamentally wrong with Windows 10, for example not allowing the users to sign in without a password etc and when it's broken at the root, no amount of UI improvement can fix it. Microsoft use to do things like a Pro, that's what made them the masters of OS market. Windows 10 doesn't feel like their product. It feels like the product of their support staff (cooks, janitors etc) with controlling and daddy issues.
I haven't upgraded from my 8.1 yet because there's just too much wrong ith Windows 10 that hamper drastically with my workflow. Though having said that I'll give the Enterprise edition a try only if they do something to the start menu.
And BTW, where is the promised Windows 10 lite version for low end PC's ?? or was it just sugar promise to get people hooked to Windows 10 ? Amazing what greed can transform you into.
