Re: What information does Win 10 slurp?
There are some GitHub projects which block/disable double digits of suspect Microsoft domains and functionality which the deceptive Microsoft security switches may not, some of my bookmarked sites for Windows 10 lock-down are:
http://www.majorgeeks.com/files/details/destroy_windows_10_spying.html
https://modzero.github.io/fix-windows-privacy/
The above tools disable lots of dubious OS functionality and domains.
A Windows 10 Enterprise version is probably the safest because it can be formally locked down even more than the Professional version, but it should be commons sense to never do any personal stuff on work kit which you not OK with being monitored, because some employers do, so no private, NSFW or P2P stuff.
I also block several domains, I never want any machines to access, in my router's domain filter, just-case an OS tries to bypass my lock-down measures.
