If I could buy the Pro version as an individual, and run it on an isolated machine, as I've done with every prior version of Windows I've purchased, I probably would have upgraded by now.

Since they don't offer that, and the non-pro version treats ALL users as imbeciles who cannot manage to keep their machines secure and up to date, and who are unable to decide for themselves if the benefits of participating in usage metrics gathering, voice-operation, and integrated web and local search outweigh the risks and costs, I'll be sticking with Win7.

Are you thinking of the Enterprise version?

Pro is available just fine: https://www.amazon.com/dp/B00ZSHDJ4O/

And my Win 10 is Pro since i upgrade it from Win 7 Pro.

Hmm, I am. Does the Pro version support turning off the privacy and updating features without being joined to a domain? If there is only partial control, that's not good enough. Otherwise I may owe you a beer :)

I'm sorry, but i have no idea what it does in regards to privacy features.

I do however have access to this, and it works: http://i.imgur.com/9dutfsY.png

Important: installing many big update packs manually will toggle this setting back.
