Q. I clean installed to Windows 10 and have been keeping up with updates. With a recent update, I have been having issues with CPU and Memory.
When I check Task Manager, Service Host: Local System is constantly running at about 25% CPU usage. It occasionally surges or stops for a couple of seconds, but soon goes back to 25% CPU usage. Its memory usage starts around 230MB as soon as I log in and then climbs at a rate of about 1MB per second to over 1.5GB. I have seen it go as high as 2.3GB. If I open Task Manager as Administrator, then I can end End Task, but then certain things like my Start Menu and Search stop working. However, after about a minute, CPU and memory usage go back to their previous states and the process shows up in Task Manager again, but the broken things continue to not work.
I assumed this could be a driver issue, but when I checked all my drivers, the only one which updated was my display driver. I have the same problem after the update.
Answer.
Restart the computer and check. Also, check for Windows updates.
Uninstall/disable any third party security software and check if it helps.
Try to run the following commands and check if it helps.
- Type CMD in Search. Right click on it to run as an administrator.
- Type the following 4 commands at the CMD prompt:
WSReset.exe.
dism /online /cleanup-image /restorehealth
sfc /scannow
powershell
Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like “*SystemApps*”} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
- Close the CMD window.
- Check to see if the issue is resolved. If not, restart the PC.
