Windows 10: Data usage by ntoskrnl

So I try to play league of legends and out of nowhere my game starts lagging, high ping for a very long time . So I open task manager and see that ntoskrnl.exe System is using my network. This has been going for more than a month and I've tried so many things to resolve it :changed something with my virtual memory, ran a windows defender scan both a full scan and an offline one, turned off all background services beside Microsoft ones, and i cant seem to find a solution. everything is updated and the problem comes and goes at very random times and stop on its own.

Data card usage in windows 10

Hi,



I understand your concern and will assist you to resolve this issue.

I suggest you to follow the steps to check which application is using Data.

• 
  Open the Settings app, and click/tap on the
  Network & Internet icon.
  
• 
  Click/tap on Data usage on the left side. You will now see a general overview of the network data usage from the last 30 days on your PC.
  
• 
  Click/tap on the Usage details link on the right side under
  Overview.
  
• 
  You will now see how much network data has been used by each app from the last 30 days.
  

After that go to task manager and End Task the Application which uses the internet.

• 
  Press ctrl +shift +Esc to open Task manger.
  

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help

Unknown data usage

The Nokia Lumia Windows Phone has a very good considerable battery life. I wouldn't worry with having the Battery Saver featured enabled much because honestly you won't need it unless in case of emergencies. The data usage is very much so defined by your
wireless carrier more than Windows Phone. You may need to contact them directly to ask why your data usage is increasing if you are not changing from your regular routines and the usage was not the same in usage.

This can also be defined by observing the things you do with Windows Phone. Your service area also defines when and where your data is used by the phone automatically because in a sense it tells the phone the only way it can function at certain times is
via the data connection (hence increasing the data usage on your wireless plan). You can always disable the data features on Windows Phone. This is mainly what I suggest you do until you contact the carrier directly and alert them of what is going on. You
should also consider using an unlimited data plan, or a data plan that only allows for WiFi usage. The very last step is how to completely disable the data features, but you can also try these steps as well to improve your data usage overall, follow
these steps and then call your carrier to inquire about the data options you have:

If you don't have an unlimited data plan, you may be looking for ways to shave a little bit off of your data usage. This topic provides a few ways to turn down or turn off some of the features that require a data connection on your phone.
Turn on Battery Saver
Battery Saver turns off some, but not all, of the features that require a data connection. You can turn it on whenever you want, or set it to turn on automatically when your battery is low. To learn more, see Battery:
making it last.

• 
  On Start, flick left to the App list, and then tap Settings
  
  > Battery
  saver.
  
• 
  Do one or both of the following:
  
  • If you want Battery Saver to turn on whenever the battery gets to 20%, select Always turn on Battery Saver when battery is low.
  • If you want to turn on Battery Saver now and leave it on until the next time you plug in your phone, select Turn on Battery Saver now until next charge.

Change email sync settings
You can choose how often your phone automatically syncs email, or you can sync it manually, just when you want to.

• 
  On Start, flick left to the App list, and then tap the email account whose settings you want to change.
  
• 
  Tap More
  
  > Settings, and then tap Sync
  settings.
  
• 
  Tap the Download new content list, then tap a time. If you don't want your phone to ever sync email from this account automatically, tap Manually.
  

Turn on airplane mode
If you're looking to turn off your cellular connection just for a while, an easy way is to turn on airplane mode.

• 
  On Start, flick left to the App list, and then tap Settings
  
  > Airplane
  mode.
  
• 
  Turn Status to On.
  

Stop sending usage feedback with a data connection
Your phone can send feedback to help improve Windows Phones, but you can choose not to send this feedback using a cellular data connection.

• 
  On Start, flick left to the App list, and then tap Settings
  
  > Feedback.
  
• 
  Clear the Use my cellular data connection to send feedback check box.
  

Turn off your cellular data connection
The most thorough way to make sure you're not using data is to turn off your data connection altogether.

• 
  On Start, flick left to the App list, and then tap Settings
  
  > Cellular.
  
• 
  Turn Data connection to Off.
