Windows 7 Pro and Win 7 Ultimate users get Win 10 Pro, but apparently Home is the standard upgrade path from all versions of Win 8.1.
 
Running down the list of differences, it looks as though I'm not giving up anything essential in going from Pro to Home. I've never hosted a remote desktop session (only as an RDC client, which I can still do), never used Bitlocker or Azure AD.
 
I can live with the forced updates, I guess. But I'm waiting for the inevitable day when an automatic update kills millions of computers around the world simultaneously and there's no way to prevent it short of pulling the network cable.
 

bit,
I upgraded from 8.1 to Win10 Pro, but I started out with Win8 Pro. I suspect you may not have had Win8.1 Pro loaded.

Possible moot point but windows 8.1 pro does update to win 10 pro. (That's what I got).

Also, I have wondered whether "home" might be a better choice than "pro" for a DAW.
I am  _speculating_  that the extra networking stuff in "pro" may unnecessarily use more ram/cpu than "home".

I guess I didn't have 8.1 Pro after all. Well, no big. There is nothing unique to W10Pro that's relevant to audio. There may even be one or two unnecessary background processes that aren't running in Home that I'd probably turn off anyhow.
 
I just completed my first SONAR project under Win 10. No I'm not that fast, it's one I started a few days ago. The only odd thing I noticed was that Kontakt libraries seem to load very slowly. This particular project has multiple Kontakt instances and it takes 5 minutes to load the first time and 3 minutes on subsequent loads. I'm pretty sure that yesterday it took less than a minute, although I didn't have my stopwatch handy. Anyone else notice this?

Kontakt libs are very quick to load. Play libs still on the slow side.

I did notice the other day that Windows Defender real time protection is always 'ON' when launching,  doesn't maintain the selected off state as it did before.
I always turn it off, several times now I've heard an audible click through my soundcard. This has never happened to me before in any previous version of Windows.

Make sure to take the time to configure Win 10 to meet your needs. There are a lot of things that you should look at. Updates was a big one, particularly the options for where you get updates. 
 
As for updates in general, I find that 90% are just definition updates for MS security essentials. I get 2 every single day (24hr). It used to be silent definition updates but now it nags. Actual program changes seem infrequent.

Yeah, Windows 10 will turn back on Windows defender after a few days.
I got this notification the first time I turned it off:
"You can turn this off temporarily, but if it's off for a while we'll turn it back on automatically."

I am not certain because I was not looking for issues, but I do think it is taking much longer to load templates and projects with Win10. I have a few VSTs in my main template including Kontakt, so Kontakt could be loading slower with Win10. It is not slow enough to bother me, but I think it is real.

Win7 pro will upgrade to win10 pro. Not surprised they put you down to home they probably want you to pay for an upgrade in future. They are also conning enterprise users into paying up as well, stating they cannot upgrade to 10... When they can legitimately downgrade to pro and then update to 10.

The big advantage of win10 is ability to defer updates. There are other advantages as well which may not be immediately apparent. I strongly urge you to take advantage of this. People are upgrading from home just because of this feature.

Nope. You can turn off the pro features you don't use. MS may also be releasing exclusive pro features in future you may regret not being able to take advantage of. Maybe even features exclusive for DAW environments (for all we know).

"I guess I didn't have 8.1 Pro after all. Well, no biggy."

Missed this sorry.
