First if you are on a connection from a mobile broadband device you will want to limit the usage so how do you do this in Windows 10.
- Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.(If you’re using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, click Settings, and then click Change PC settings.)
- Tap or click Network, and then tap or click Connections.
- Tap or click the connection you want to change, and then, under Data usage, turn Set as a metered connection on or off.
Next :Turn off background apps
Windows 10 keeps some apps running in the background such as the Mail app.
Turn off some of these apps by going to Settings > Privacy > Background apps.
Then turn off apps that use background data that you don’t need.
