I think that they have a list of approved ISPs or some dependable way to make sure it doesn't happen on metered connections.

"As with Windows 8.1, Windows 10 won't automatically download updates or apps if it detects that your PC is using a metered connection. Similarly, Delivery Optimization won’t automatically download or send parts of updates or apps to other PCs on the Internet if it detects that you're using a metered connection."

Don't you actually have to specify that your connection is metered in order to that to work?

I think it's for tagging things like wireless hotspot, etc.

I'm not sure exactly how it works but there is documentation on what they're calling "Connection Cost".

I wonder how they get those values, considering bandwidth limit parameters can vary depending on contracts even when it is happening to identical networks...

(Perhaps some UI allows users to to put this info, similar to Android settings?)

They have some samples that you could use: https://code.msdn.microsoft.com/windowsapps/Network-Informat...

What it does matter if it's metered or not? I've got metered connection, it's 10TB / month included + 1€/TB for excess (outbound). I don't usually worry about little extra traffic.
