I don't understand why you would want to disable LAN distribution of Windows 10 updates to your other Windows 10 machines. It seems like a great way of avoiding multiple downloads of the same thing, and I'd love something similar for Linux (aptorrent or something; manual rsync of /var/cache/apt/archives isn't quite the same, neither is apt-mirror).

Disabling uploads to other external machines does make sense to me, though.

Probably not much point in disabling that. Disabling downloads from other machines on the web makes more sense if you have a data cap or are charged per MB, which is common in some countries. It's not really a privacy-related change as far as I can see.
