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.

Best regards

Problems with High network usage by service host : Network service

Hi, Ive been having the problem with Service Host : Network Service, in which its using far too much network, up to 16 - 20 Mbps in some instances, as can be seen in this screenshot (Okay it wont let me add screenshots for some reason, but its still high usage). I have disabled the BITS service, and have checked updates, but it wont allow me to install the most recent due to the high internet usage, it always gets stuck. The updates that cannot be done are: "024-03 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5035853)" and "Intel Corporation - Display - 31.0.101.5186" the second of which has the error "Download error - 0x800706ba". I have also tried all of the methods from this website: Service Host Network Service High network usage in Windows 11/10 and this thread: Redirecting as this user seems to be having the same problem I am. I have also scanned the device with the most recent windows security check and that has found nothing on a full scan.

Its driving me insane and making my Wi-Fi unusable, please help.

 

Help needed with simple wired network

Step one- Connect all PC's to router, and then the router to the modem. PC's go to router by the ports labeled "1-4" on the back of the router. WAN port goes to router. Power up all network equipment, and then systems.
Step two- Power on the computer connected to port one. Go into router settings at 192.168.0.1 and configure internet, dyndns, firewall, etc.
Step three- Go to "network set up wizard" in windows. (Network places- network set up wizard). The rest is self explanatory.
Step four- right click on each drive and printer you want to share, and then configure sharing preferences. Should be easy enough.
Step five- right click my computer, and the select "map network drive". Using the network address for each piece of hardware you shared, assign network drive letters.

Congratulations, you have a fully operational network. Happy Gaming! *Toast :toast:
