Block Traffic from Microsoft Ports

For some, the first three fixes stop the “Service Host: Network Service” notification from showing up, but the internet speed doesn’t improve. So we will have to stop outgoing traffic from some Windows ports to stop any traffic leaks. The Windows Updates Delivery Optimization uses TCP port 7680 and UDP port 3544, so we will be creating a firewall rule so that any outgoing traffic on these ports is blocked.

Another way to disable the Windows Update Delivery optimization is through the registry. To do this press the Windows key + R >> type “regedit” in the Run dialog box and press Enter >> in the Registry Editor window, navigate to this registry key on the left pane, and click on it: “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DeliveryOptimization\Config” >> on the right pane, you would select New, then DWORD Value >> you will now name the registry you created “DODownloadMode” >> to modify the DWORD Value data, you just have to double-click on it >> you now have to enter the Value data that corresponds with what you’d like to do, in our case that will be turning OFF Windows Update Delivery Optimization (1) >> you can now save, close the registry and have your PC reboot.

Here are other value data below:

  • 0 – turn Off Windows Update Delivery Optimization
  • 1 – turn On Windows Update Delivery Optimization for local network only
  • 2 – turn On Windows Update Delivery Optimization for local network private peering only
  • 3 – turn On Windows Update Delivery Optimization for local network & Internet
  • 99 – Simple download mode
  • 100 – Bypass mode

Scan Computer for Malware

The next thing that could be causing the “Service Host: Network Service Using Internet” issue is malware on your computer. So you would want to scan and remove any malware. To do this, you can use Windows Defender or any other antivirus software.

To use the Windows Defender go to Settings in the Start Menu (or by pressing Windows + I) >> click on Update & Security >> on the left pane, select Windows Security >> click on Open Windows Security >> click on Virus and Threat Protection >> click on Quick Scan or Advanced Scan and just wait for the scan to complete.
