Windows 10: LocalServiceNoNetworkFirewall Consumes Large Amount of CPU on a Regular Basis

For the last 3 weeks or so, the service LocalServiceNoNetworkFirewall has been consuming 40 to 50% of my cpu. If I restart the system multiple times, I am sometimes successful in lowering the amount of cpu being used by LocalServiceNoNetworkFirewall. I am running Windows 10 version 1909 OS Build 18363.752.

System and compressed memory background process persistently consuming high CPU resources

Hi,

Thank you for posting in Microsoft Community.

Please answer these questions to get more clarity on this issue:

1. Did you make any changes to your computer prior to this issue?

2. Which anti-virus program is installed on the PC?

High CPU usage occurs for various reasons, for example: virus/malware infections, out-of-date drivers, anti-virus programs or other third-party programs, etc;

Method 1: Windows has a built-in troubleshooter to check and fix issues with system. I would suggest you to run this troubleshooter to check if the issue is with your System
Maintenance.

Refer these steps:

• Press Windows key +X, select Control panel

• Change the view by option on the top right to Large icons
• Click on troubleshooting and click on the view all option on the left panel

• Run the System Maintenance troubleshooter

Method 2: Check if the issue resolves in
Safe Mode.

Refer this article to boot to safe mode:

http://windows.microsoft.com/en-us/windows-10/change-startup-settings-in-windows-10#v1h=tab01

Steps to reduce the CPU usage.

1-Press "Ctrl," "Shift," and "Esc" on your keyboard. This brings up the task manager without any intermediary screen.

2-Click the "Processes" button on the task manager.

3-Click the "CPU" column header until the arrow next to the label points down.

4-Right-click a program you recognize that uses a high percentage of the CPU and click "End Process." Click "End Process" to reconfirm. This eases up on the CPU's load. Use this step if you're not using a process or if the process has stopped responding. Do
not use this procedure for windows processes.

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

Thanks.

 

Service host tasks consuming large amount of processor

On what appears to be every other boot of my computer, I find that three service host tasks consume a significant amount of CPU cycles.



If I let the computer sit, untouched, for 10-15 minutes, these three tasks remain the greatest consumers of cpu time. If I reboot, however, they stop being cpu hogs:



What surprises me is that I can reproduce this behavior by simply rebooting my computer, at which point the three service host tasks will resume their place as top CPU users.

I am looking for suggestions on how to troubleshoot this issue.
