Now that Windows 10 is a universal operating system, Microsoft has built in some data-monitoring tools for users with a limited data connection.
Desktop users probably don’t need to concern themselves with network data usage, but tablet and laptop users may find these tools helpful.
See How Much Data you’ve using
For a very basic overview of your network usage, you can open up the Settings menu and go to Network & Internet and click Data usage.
Here you’ll see a donut graph that shows how much data you’ve used over what types of connections in the last 30 days. In my case, I’ve only used data over a wired Ethernet connection, but if you switch between Ethernet, Wi-Fi and mobile data, you’ll see a mix of sources.
Set up a metered connection
If you don’t want Windows to automatically download large updates (including app updates), you can set your Wi-Fi connection to “metered.” To do this, go to Settings > Network & Internet > Wi-Fi, scroll down to the bottom of the list of Wi-Fi networks, and click Advanced options.
In the Advanced options menu, you’ll see an option to turn Set as metered connection on or off.
Simply limiting your connection isn’t enough to really save data — while it means you won’t get big Windows updates until you connect to a non-metered connection, apps will still run and sync in the background.
