Issue: How to Fix High CPU Usage by Service Host on Windows 10 V1709?

After the installation of Windows 10 Fall Creators Update, two processes, Service Host: Local network and Service Host: Internet Connection Sharing, triggers high CPU usage, which sometimes jumps to 50 or more percent. The PC gets really sluggish. Could you please tell me what could I do?

Solved Answer

For the past couple of weeks, Microsoft forum is full of users’ reports about Windows 10 Fall Creators Update bugs. Sadly, there is a multitude of problems, one of which is related to high CPU usage by Service Host processes (Service Host Local Service and Service Host Internet Connection Sharing).

According to new Windows 10 V1709 users, these two processes use more than 30% of CPU, and, therefore, diminish the performance of the system. While the culprit of the problem may differ on each case, usually the Service Host high CPU is triggered by the stuck download process of Windows Update.

However, the problem can also root from the failure of other Windows services, for example, Internet Connection Sharing (ICS) or Base Filtering (BFE) Service. Therefore, a temporary solution for high CPU usage by Service Host would be to disable the services indicated above.

High CPU by Servic Host

If that did not help to fix the problem at least temporarily, try the methods provided down below:

Method 1. Disable ICS or Base Filtering (BFE) Service

Internet Connection Sharing (ICS) (SharedAccess) is one of the default services in Windows 10. It is responsible for the provision of network address translation, addressing, name resolution and/or intrusion prevention services for a home or small office network.

The ICS is dependent on other Windows processes, including BFE. If the latter can’t start for some reason, ICS process keeps waiting, failing, and restarting continuously resulting in the high CPU usage by Service Host. Thus, try to stop ICS and BFE processes:

  • Press Windows key + R, type services.msc, and press Enter.
  • First of all, find the Internet Connection Sharing (ICS) service, right-click on it, and select Stop. Few people reported that right after stopping it, they received a BSOD screen, which triggered a reboot. Nevertheless, after system’s reboot, the high CPU usage by Service Host has been fixed.
  • If that did not help, stop the BFE service and check if the problem was resolved.
Disable Windows processes

NOTE: this fix is temporary because the BFE and ICS services typically automatically. Thus, you can apply this method until Microsoft releases the patch.

Method 2. Use Command Prompt

  • Right-click on Windows key and select Command Prompt (Admin).
  • Click Yes on the UAC window and paste the following commands into the Command Prompt window:
    DISM.exe /Online /Cleanup-image /Restorehealth
    DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
    sfc /scannow

IMPORTANT: C:RepairSourceWindows stands for the location of your repair source.

Use Command Prompt to fix Service Host error
  • Close Command Prompt and check if the problem has been resolved.

    There is a much easier, and safer solution:
    Reset the Windows Defender Firewall to the default settings.

    To do this open
    Settings -> Update and Security -> Windows Defender -> Open Windows Defender Security Center -> Firewall and Network Protection -> Restore Firewall default settings

      Resetting firewall settings worked for me like a charm. I had this issue for long time and I just figured out that I had a lot of custom rules so I decided to backup them and reset it - and CPU usage went down from 25% to 0-5%.
