Thing with Pro is that you used to be able to turn off a lot of the annoying shit via group policy, but then MS blocked a lot of this in the anniversary update as they want businesses to use the more expensive Enterprise.
Interestingly enough, I'm a contractor at one of the biggest companies in the world, and we've recently started rolling out Windows 10 Pro, so I guess they've found adequate way to suppress the nasties. For me, it's the forced updating which is the main reason I've not put 10 on any of my PCs. Well, that and MS's frankly appalling attitude of trying to ram it down everyone's throats last year.
It would appear yes, but does of course involve paying MS some money.
Personally, I'd Jim it, but then I'm pretty disgusted with how MS have approached the whole ram-Windows-10-down-your-throat mess, so currently I'd rather clean out a septic tank with a toothbrush than give Microsoft some of my money, but hey-ho!
Can't remember the source, but apparently there's a way to download a legit free 10 from MS if you go in through some kind of special accessibility portal/page. So you get a free accessible version which you can then tweak to run like regular version.
It's the "Accessibility" edition or whatever it's called, pretty easy to find - but that's for upgrading from 7 or 8 to 10, not for going from Home to Pro editions, that's normally a paid-for extra.
I think I just lost my patience with the Dell stuff installed that was popping up. Albeit not a lot installed but I'm just used to clean Windows installs with no bloat. I'll probably partition and dual boot 10 Pro sometime soon.
Just need to find a desktop environment that handles HiDPI screens nicely. Could do with some granular scaling.
I had to swap in old (& with bad sectors) hdd, format it and clean install 7 pro, then upgraded it to 10 whenever the rc came out. No dell cruft on board.
