With the methods shared below, you can not only see which apps are using the network but also display all network usage. Users can view a list of apps that have used the network in the past 30 days. Whether an app is communicating with a remote server over the Internet or a local network device, this information will be displayed.
1. Check network usage level.
2. Launch Resource Monitor.
3. View network data usage.
1. Check current network usage level using Task Manager
Task Manager will precisely inform you about which applications are currently using the network and the amount of data they're downloading and uploading.

In the process list, click on the Network item to sort running processes by network usage. Check the list, and you'll see which apps are using the network along with the amount of bandwidth they're consuming. (If you don't see the Network heading, click on More Details first).
Technically, this isn't a complete list if a process isn't using much network resources. Windows rounds down to 0 Mbps (Megabits per second). It's just a quick way to know which process is using a significant amount of bandwidth.
2. Open Resource Monitor for more details
To find out more information, open the Resource Monitor application. You can open this application by searching for the Resource Monitor keyword in the Start Menu or clicking on the Performance tab in Task Manager and selecting Open Resource Monitor below the window.
Next, you select the Network tab and a list of processes downloading and uploading data over the network will appear. You'll also see the amount of data they're transferring in B/sec (Bytes per second).
This also shows processes using a small amount of network bandwidth, which also appear as using 0 Mbps in Task Manager.
With both the list in Task Manager and Resource Monitor, you can right-click on the app and select Search Online to find more information about what exactly this process is.
3. View network data usage over the past 30 days
Windows 10 monitors which apps are using your network and the amount of data they're transmitting. You can view which apps have used the network in the past 30 days and the amount of data they've used.
To find this information, you go to Settings > Network & Internet > Data Usage and click on View usage per app at the top of the window.
Here, you can browse the list of apps that have used the network in the last 30 days. If you're connected to a Wi-Fi network, you can see which apps have used the current Wi-Fi network or a list of apps that have used the network on all Wi-Fi networks you've connected to. Choose what you want to view in the Show usage from box.
The top of the list will contain the likely culprits. They could be the apps you use the most. Scroll down, and you'll see some apps that rarely connect to the Internet and don't use much data to function.
