Windows 10 Metered connections
A metered connection is an Internet connection that has a data limit associated with it. Cellular data connections are set as metered by default. Wi-Fi and Ethernet network connections can be set to metered but aren't by default. Some apps might work differently on a metered connection to help reduce your data usage. Also, some updates for Windows won't be installed automatically.
To set a Wi-Fi network connection as metered:
1. Select [Start], select [Settings], select [Network & Internet].
2. Select [Wi-Fi], select [Manage known networks], select the Wi-Fi network.
2. Select [Properties], turn on [Set as metered connection].
