How to monitor the data usage of your apps, in Windows 10 and Windows 8.1
Many users do not monitor their network usage because, in many cases, internet service providers offer unlimited data plans. Because of that, the majority of the users don't really know anything about the amount of data traveling in and out of their Windows computers and devices. However, there are also users who don't rely on unlimited data plans, and instead have metered internet connections, like mobile network connections offered by telecom providers. If you're one of them, or if you just want to keep track of your data flow, then you should read this article, as we will show you how to monitor how much data your Windows Store apps use, both in Windows 10 and Windows 8.1:
How to monitor the data usage of Windows Store apps, using the Task Manager
Both in Windows 10 and in Windows 8.1, you can track the amount of data transferred over your network by your apps, with the help of the Task Manager. However, you should know that this method will work only for monitoring the network usage of universal Windows platform apps and other apps that are found in the Store. This method doesn't work for classic Windows desktop programs.
On your Windows 10 or Windows 8.1 computer or device, launch the Task Manager. There are many ways to do that, and we've covered all of them in this guide: 10 ways to start the Task Manager in Windows 10 and Windows 8.1. However, if you don't have time to read that guide too, a quick way to launch the Task Manager is to simultaneously press the Ctrl + Shift + Escape keys on your keyboard. Or, if you prefer, in Windows 10 you can search for "task manager" using Cortana's field from your taskbar.
In Windows 8.1, you can search for task manager on the Start screen.
Both in Windows 10 and in Windows 8.1, once the Task Manager opens, head to the App history tab.
In the App history tab, you'll see the list with all the Windows apps installed on your Windows 10 or Windows 8.1 computer or device. By default, they are sorted alphabetically.
One of the data columns to the right of the apps' names, called simply Network, will show you exactly how much data each of them has consumed over the last month.
If you prefer, you can click or tap on the Network header, and the apps list will be sorted by the amount of network data consumed by each app.
How to monitor how much data all your apps use (including desktop apps), in Windows 10
If you're using Windows 10, the information shared by the Data usage panel from the Settings app lets you see how much network data has been transferred by all your apps. The good thing about this method is that the Data usage panel shows how much data was transferred over your networks regardless whether they're universal Windows platform apps or traditional Windows desktop programs. If you want to see how all that works, you should read this guide: Identify which apps use the most data on your Windows 10 PC or device.
Unfortunately, this feature is not available for Windows 8.1, only for Windows 10.
As you can see, there are tools available in Windows for tracking how much network traffic apps make on a monthly basis. If you are not satisfied with what Windows provides, you can try using a network monitoring app such as Glasswire. If you have any questions or comments, share them below.
