How to Fix Service Host Local System High CPU Usage Error
You can follow the given solutions to fix the High CPU usage error caused by Service Host Local System.
We have tried to include all the solutions that can help you fix the cpu usage error. The methods will fix high memory usage error from Windows 10 and Windows 8 computers.
Solution 1 – Disable Superfetch service
On exploring Task Manager a little bit, you’ll observe that Service Host is the cause behind high CPU usage. This is irrelevant to CPU’s speed or power as it can happen on any configuration.
Anyway, Service Host: Local Service (Network Restricted) contains a lot of sub-services, and one of these sub-services is causing Service Host: Local Service (Network Restricted) to use CPU to its maximum.
This service is known as Superfetch. The main use of Superfetch is that it’s used to pre-load data from hard disk into RAM memory. You will have to disable Superfetch service for improving your performance, and getting rid of the high CPU usage. Here’s you can do it:
- Go to Search, type services and open Services.
- Find Superfetch service, right click on it and go to Stop.
3. Restart your computer.
Your CPU usage should get back to normal once you’ve disabled Superfetch service. After that, you’ll be able to continue with work on your computer glitch-free.
Although according to Microsoft, Superfetch service improves computers’ performance over time, in practice, it’s actually the opposite. It has been complained by many users that this service keeps performance optimized only when the system is newly installed, but eventually, it actually minimizes the system’s performance.
Also, Superfetch services run on very low priority, so it should not affect other IO activities. That is because normal IO activities run at high priority. It has been reported by several users that they have fixed the problem simply by disabling Windows Update and Event Log service, therefore you can try that as well.
Solution 2 – Run SFC and DISM scan
Sometimes, due file corruption, Service Host causes high CPU usage. Your system files are prone to get corrupted, but hey! There’s no need to get tensed! You can simply repair them by running an SFC scan. For that, follow the given steps:
- Press Windows Key + X to open Win + X menu. Select Command Prompt(Admin) from the list. If Command Prompt isn’t available, select PowerShell (Admin) instead.
2. When Command Prompt opens, enter sfc /scannow. Then press Enter to run it.
3. SFC scan will now start. This will take you about 10 mins, so don’t interrupt it.
After the SFC scan is finished, check if the problem is resolved. If the issue still persists, or if you couldn’t run SFC scan at all, you’ll need to use DISM scan instead. To do that, follow these steps:
- Open Command Prompt as administrator.
- When Command Prompt starts, enter DISM /Online /Cleanup-Image /RestoreHealth.
3. DISM scan will now start. This process can take 15-20 minutes so do not interrupt it.
After the DISM scan is finished, check if the problem still persists. If you were unable to run SFC scan before, try running it now. The problem should most probably get resolved after both scans are completed.
Solution 3 – Run Windows Update troubleshooter
You might be able to fix this problem simply by running Windows Update troubleshooter. The problem can be related to Windows Update if Service Host is causing high CPU usage. By running the troubleshooter you should be able to fix it. For that, follow these steps:
- Press Windows Key + I to open the Settings app.
- When Settings app opens, navigate to Update & security.
3. In the left pane, navigate to Troubleshoot section. Select Windows Update and click Run the troubleshooter.

Both methods are capable of checking Windows Update and can fix any potential problems.
After the troubleshooting is finished, check if the issue still appears.
Solution 4 – End unnecessary HP processes
The cause might be related to HP processes that are running in the background if Service Host is causing high CPU usage. For rectifying this error, you need to end all the HP processes from Task Manager by doing the following:

5. In System Configuration window, you need to click Apply and OK to save changes. For applying the changes, you will be required to restart your PC.
After restarting your PC, check if the problem still persists. If not, then one of the disabled applications or services was the cause of this problem. For ruling out which application caused the error, enable apps and services one by one or in groups until you find the one that is causing this issue. After finding that problematic application, either disable it, remove it or reinstall it. Then check if that solves the problem.
Solution 7 – Change processor scheduling
It has been observed that by changing the processor scheduling you might be able to repair the damage if Service Host is causing high CPU usage. This can be easily rectified by following the given points:
- Press Windows Key + S and enter advanced. Choose View advanced system settings.
- When the System Properties window opens, in Performance section click on Settings button.
3. Search for Advanced tab and set Adjust for best performance of Programs. Then click on Apply and OK to apply the changes.

If Service Host is causing high CPU usage, you might be able to fix the problem simply by restarting Windows Update service. To do that, follow these steps:
- Open Command Prompt as administrator.
- Now run the following commands:
- net stop wuauserv
- net stop bits
- Minimize Command Prompt.
