Windows 10: High CPU usage from Service host local system (2)

Windows 10 up to date

HP Probook 450 G2

CPU: Intel i5

SSD: 150Mb

NIC: dual band


" Service host local system" has been an issue on my PC for a while. It uses a lot of CPU which makes me feel uncomfortable, and today I seem to have found a fix using the SFC and DISM commands.


I wanted to present my findings in a concise report for those who only have what appears to be the lower level of problem that I had. I notice that probably all the other reports are for far more serious situations, but there is nothing for those of us requiring a simple solution.


At an Administrator command prompt, enter the SFC and DISM commands (see below). They took about 10mins each to run on my PC.

sfc /scannow


Followed by -:


Dism /Online /Cleanup-Image /RestoreHealth


In both cases for me the results came back without errors and with a noticeable improvement in CPU behaviour.


I have noticed for a long time that my PC suffers lots of activity from "Service host: local system (2)". If left alone it eventually does what is needs to and stops, but I really don't know what it does. Thankfully the SSD that I installed a year ago has improved the performance so much that I don't notice a drop is responsiveness. But sadly I am one of those people who incessantly feels uncomfortable if things "don't look right" and then asks 'why?"; and then have to find an answer.


After looking at Answers and Technet it appears that some unfortunate soles have far more complex variants of the problem than I seem to have had and therefore for those with my simple variant, ploughing through all the complex solutions could prevent a user finding an easy fix.


So I found this and I decided to look at the help for the commands and then use them.


The result was -:

1. No obvious Service host local system (2) afterwards
2. Generally a quiet CPU
3. Apps like anti-virus at the top of the list and swapping with other apps that I expect to see running. So now the process list appears how I would hope it to.
4. Depending on what I am doing, the CPU can rise to nearly 100% and then eases off as the processing is done and then settles to near zero as if there is nothing holding it back. It's a totally different PC now.

I think there is reason to claim that my PC is operating more effectively - for the moment...


HTH
