Windows 10 provides a detailed summary of apps and their total data usage. This can be a useful metric to estimate which apps consume a lot of data and which don’t especially when using metered Internet connection.
To view this data usage :
Go to Windows Settings by clicking on All settings from the Action Center.
Next, choose Network & Internet.
Select Data usage > Usage details.
This will show a breakdown of data consumption per app in descending order.
Browsers and file transfer programs will usually show the highest but if any other app is also on the list which usually shouldn’t, then it may need further action.
