No. Getting Windows 10 is not worth it because its got massive amounts of spyware in it and forces you to constantly upgrade, Cortana is always listening so potentially you lose all form of privacy. I'm waiting for some pirate group to liberate Windows 10 for those of us who don't want to lose it.

Windows doesn't have a comprehensive internet socket system like BSD or UNIX, so you can't actually tell if it is opening a network connection - because it doesn't use sockets. The problem is that Microsoft shipped Windows 10 with spyware that could be exploited by the NSA or hackers. You should not be so trusting. I use Windows 7 for this reason. I don't trust Windows 10 and won't.
