Download Offline Maps over Metered Connections in Windows 10

Windows 10 comes with a built-in Maps app powered by Bing Maps. It is Microsoft's own answer to Google Maps which are available on Android and online. Maps can be useful because of voice navigation and turn-by-turn directions. They can be used to quickly to find directions or locate a building. To use Maps when offline, you can download them in advance. Here is how it can be done in Windows 10 when the metered connection feature is enabled.

The maps app has landscape mode and supports turn-by-turn directions for quick glanceable information so you can watch your mobile device's screen while you are on-the-go. The maps app also has a nice guided transit mode which comes with notifications for your stops.

The Maps app has its own section in Settings. By default, maps will be automatically updated only when your device is not on a metered connection. You can change this behavior.

To download offline maps over a metered connection in Windows 10, do the following

1. Open the Settings app.
2. Go to Apps & security -> Maps.
3. On the right, scroll down to Metered connections.
4. There, turn on the option below the Metered connections label and you are done.

This option can be enabled or disabled with a Registry tweak. Here is how.
