Windows 8 and Windows 10 allow to mark Wi-Fi networks as metered in Settings > Network & Internet > Wi-Fi > Advanced Options. There is no GUI option to do the same for Ethernet / LAN connection. Luckily the same result can be achieved by a small registry change.
- Open regedit.exe and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\DefaultMediaCost

- Now open Ethernet key and change its value from 1 to 2.
