Windows 10: 'System' data usage over 25GB; how do I decrease System data usage?

My data usage is currently over 25GB in the last 24 hours. It's the same in the last 30 days too.I'm wondering how I can decrease data usage in my System, and wondering why and how it's so high. I'm trying to install a game, and it's downloading at around 20 Mbps, when it should be downloading at around 200 Mbps.

High System data usage

Hi, the common suggestion for System data usage being high is related to Windows Update. However your data usage is so high that seems improbable. Given that, what does your Windows Update History show you? Please provide a screenshot. That said, it also seems improbably this is the cause- your build number is the same as mine. You can get a more complete picture- and perhaps convince yourself whether it is app-related usage or not from this:

You can break down current System usage with Process Explorer.

Note the column I've added on the right- data from the internet. You can monitor disk and internet activity.

 

data usage system

Hi Mohammad

Open the Settings App, go to Network and Internet - Data Usage - View Data per App

Is 'System' listed as using a lot of data?

If so, in the Settings App, go to Home - Update and Security - Delivery Optimization

Turn off Delivery Optimization, then click Advanced Options

Pull all sliders on that page to their minimum values

That will reduce the amount of data used by System . . .

 

System data usage

We appreciate the additional information that you have provided. As the screenshot shows, System has used only 8.77 GB of data usage which is the estimated calculation for 30 days. The details that show that the data is for the past 30 days can be seen on
the Overview page before clicking on Data usage. These data usage could have been acquired if there are downloaded updates on your computer.

Regards.
