One of the less obvious features in Windows 8.1 is the ability to track data usage on a connection — handy if you're using mobile Wi-Fi or a limited connection in a hotel. Here's how to set it up.
To enable this option:
- Make sure you're connected to the network you want to measure.
- Bring up the Settings charm by swiping from the right (or type Windows-I).
- Choose 'Change PC settings'.
- Choose 'Network'.
- Under Data Usage, switch 'Show my estimated data usage on the Networks list' to 'On'.
With that option enabled, you'll see estimated usage if you tap on the Networks icon in Settings. It's a potentially useful second check against other estimates (such as those provided by your carrier).
