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.
