Decided to take a look at it today so I popped it in on my NUC.
One thing that is nice, if you have an activated Windows 7/8 you don't need to run the old upgrade utility to activate from 7 to 10. I have it, but I never bothered running it. Instead, it accepts you typing in the Windows 7 product key (and 8 as well I believe) and it'll activate. So, now I have an activated 10 Pro without having to run any of the third party utilities. Which is nice, because you can download the .iso directly from MS, all you have to do is change the user agent on your browser to a non-Windows string and it will let you download an .iso so you don't need to use their tool to construct whatever.
I honestly don't know why people like 10. Eye issues critiques aside, it just feels slower, heavier and clunkier than 7 which is really nice and responsive on my NUC. It really shows how there's still a ton of Vista/7-era elements still kicking around that MS just slapped stuff on top of.
Even Netflix, while sure it's nice that it lets you use full resolution, there's this "smoothness" to it that doesn't feel right to me which is likely due to the display compositor, it reminds me of the soap opera effect on TVs where tvs interpolate frames. I do prefer video on 7 for netflix, the framerate feels more natural. Of note, I also don't have this weird smoothness on my Android phone either which is whitelisted for full resolution.
Having it search for a driver update for my monitor had it install the same colour profile as I have in 7, so that took care of the harsh white that some here have commented on that 10 has. I would suggest you have it search for an updated monitor driver in your device manager, it very well might bring a colour profile along.
Played around with different display driver versions from multiple different years for fun. I can see subtle differences between them but that doesn't change the fact that I just don't like 10, it doesn't feel nice like a planned OS like Vista/7 is with the Aero interface. I use 10 (1809) every day Mon-Fri on my work laptop, so it's not solely a get used to it thing.
WDDM # stayed at 2 for every version of the display driver I tried including the same one I use on 7 as well as the latest one available from Intel for download for my 5th gen cpu with HD 6000. Probably it'll never be updated past 2.
If I was forced to, I could use 2004, but I don't want to you know? It just feels more comfortable in 7 for me, and I have everything set up the way I like it.
Makes me laugh how Windows 10 still has two separate control panels. The gear icon, and the real one.
Guess I'll try build 20150 beta for the heck of it which is the 20H2 update scheduled for November.
