Yes, this is called "delivery optimization" and it's on by default. By default, Windows Enterprise/Education only pull updates from Microsoft and the local domain, while Windows Home/Pro will also pull updates from other peers on the internet.

You can turn it off, or disable pulling from internet peers, but given the OP, who knows if MS actually respects that setting? I guess we have to roll the dice now.

Maybe they changed it, but I just checked my fresh install of Pro build 1703 from MSDN and it was disabled.

Odd, their docs say it's on by default.

One of the handful of tools I installed from Ninite must have turned it off then. After a quick look, I'm guessing it was Classic Start Menu.
