I have to use Windows for work, and I'm beginning to regret switching from 8 to 10. But I really didn't like Windows 8. So, maybe back to 7... I also have my main home PC on Windows 10 because I use a lot of Windows software. Sigh. Maybe that one has to go back too. Or maybe Windows has to go into a VM on Linux. Damn, just when I thought Microsoft were improving they turn out to be shadier than ever.
Yeah, I have used linux in the past for about a year, and now I'm seriously considering of upgrading from Windows 8.1 to Debian instead of Windows 10.
Oh man, this takes me back to middle school. Had gotten my first laptop, an amd box running 64bit vista, and man were those bundled parental controls fun. I probably wouldn't have gotten into computing as much as I am if I hadn't gotten so pissed off at the restrictions UAC and parental controls enforced. Ended up booting linux off a slider phone's sd card while in usb mode just to use chntpw and promote myself to admin. On the side I also did that to my cousin's computer and while my parents didn't care much anymore that I had did that to my own, boy was my cousin's mother pissed. On the bright side of that, I actually earned a good amount of how the registry works and the SAM hive.
You would have to block all outgoing connections to prevent this unauthorized communication. There is no exhaustive list of domains or IP addresses that are used to send your personal information. The best solution is really just to not use Windows 10. GNU/Linux operating systems like Debian, Mint, and Arch respect your privacy by default.
