I genuinely upgraded to 10 pro, but after seeing the ridiculous amount of spyware traffic being sent, I installed Enterprise 2015 LTSB instead, none of those useless apps, no store, no Edge browser, and the ability to disable telemetry from gpedit, but I wasn't born yesterday so I imagine there will still be plenty of stuff being sent - just nice not to have any of that tablet UI crApps any more
