backgroundtrasferhost.exe using high network bandwidth

Hi Govind,

Could you also let us know if you are using a wireless or a wired connection? If you are using a wireless connection, please connect using a wired and check if the same issue occurs. Also you may want to run a complete scan using the inbuilt Windows Defender
to eliminate any suspicion of infection.

This service also transfers files in the background using idle network bandwidth. Applications which depend on BITS such as Windows update and MSN Explorer automatically downloads programs and other information while the connection
is idle.

As a troubleshooting step you may also try the steps listed below and check, but please do remember that disabling this service will lead not being able to install Windows update. Therefore I would suggest you to try this step,
check and then restart the service again. This is to let us know if indeed this service may be causing the issue.

You can disable this service by opening TASK MANAGER > SERVICES > OPEN SERVICES (Bottom Left corner) > Find the service from the list - BITS / BACKGROUND INTELLIGENT TRANSFER SERVICE > Right click, STOP > Right click, PROPERTIES
> START UP TYPE - Set DISABLED. (credit Vishwa Weerasooriya).

Hope this helps and do let us know if you need further assistance. We will be glad to help.

 

Windows 10 Store app hogs all internet bandwidth, any way to limit bandwidth specifically for it?

Try the steps below:

• Type Local services in search windows on task bar. Open Services window.
• Search for "Peer Name Resolution Protocol".
• Double click "Peer Name Resolution Protocol". On the "General Tab" select startup type"Disabled". Apply and close.
• Continue the same process with "Peer Networking Grouping" and "Peer Networking Identity Manager" and disable it.
• You can also disable "Windows Update" in same window.

I had the same issue but after trying that my bandwidth usage dropped dramatically.

 

How do I PERMANENTLY STOP Service Host: Network Service

Hi

Welcome to Microsoft community.

I understand your frustration, and I'm here to help you address the issue with Service Host: Network Service consuming excessive bandwidth on your Windows machine. Keep in mind that Service Host: Network Service is a critical system process responsible for handling various network-related tasks in Windows, so disabling it entirely is not recommended and could lead to other problems.

Here are some steps you can take to troubleshoot and mitigate the high network usage caused by Service Host: Network Service:

1. Identify the Specific Service: Service Host: Network Service is a container process that hosts several network-related services. To identify which specific service is consuming bandwidth, you can use the Resource Monitor:
   
   • Press Ctrl+Shift+Esc to open Task Manager.
     
   • Go to the "Performance" tab and click on "Open Resource Monitor."
     
   • In Resource Monitor, navigate to the "Network" tab and look for processes under "Processes with Network Activity." Check which specific process is using the most bandwidth.
     
2. Check for Windows Updates: Ensure that your Windows system is up to date with the latest updates. Sometimes, updates can include fixes for known issues, including excessive network usage caused by specific services.
   
3. Check Background Apps and Services: Some background apps and services might be causing high network usage. Disable any non-essential apps and services running in the background and observe if the network usage decreases.
   
4. Check for Malware: Run a full system scan with your preferred antivirus software to check for any malware or potentially unwanted programs that might be using your network bandwidth.
   
   Disclaimer: Running Microsoft Safety Scanner can help you check if the system is disturbed or malicious software exists. To avoid any trouble for you, please follow them step-by step and back up all your personal files first to ensure you do not lose data.
   
5. Limit Bandwidth for Delivery Optimization (Windows Update): Since you mentioned that Delivery Optimization might be the issue, you can try limiting the bandwidth used by Delivery Optimization:
   
   • Go to "Settings" > "Update & Security" > "Windows Update."
     
   • Click on "Advanced options" and then "Delivery Optimization."
     
   • Under "Download settings," select "Limit how much bandwidth is used for downloading updates in the background" and set a lower percentage value.
     
6. Reset Network Settings: Resetting your network settings can help resolve any network-related issues. To do this:
   
   • Open Command Prompt as an administrator.
     
   • Type the following command and press Enter:
     
     netsh winsock reset
     
   • Restart your computer after the command completes.
     
7. Check for Network Driver Updates: Make sure you have the latest network drivers installed for your network adapter. Visit your computer manufacturer's website or the network adapter manufacturer's website to download and install the latest drivers.
   

Remember that some network usage is normal, especially during background tasks, updates, and syncing processes. Completely stopping the Service Host: Network Service might cause unintended consequences, and it's essential to identify and address the specific issue causing the high network usage rather than disabling critical system processes entirely.

Additionally, if you believe that Windows is continuously changing your settings, consider checking for third-party applications or policies that might be causing these changes. Unauthorized changes to your system settings could be indicative of a security issue.

Always ensure you have reliable backups of your important data before making significant changes to your system.

Please feel free to let me know if you have any further updates, thanks.
