Stop Windows Modules Installer Worker High CPU Server Permanently

-
In this post, I describe how to permanently stop Windows Modules Installer Worker from using high CPU on Windows server.  As with my previous post on this subject, I would not do this on a live machine, however, it can be a pain on a test machine, particularly one that is only on from time to time as it seems to kick in as soon as you turn the machine back on.

Stop Windows Modules Installer Worker

Stop Windows Maintenance Modules Installer Worker from ever being started by Windows Maintenance tasks by downloading PSTools and running the following commands:

Server 2012 R2

psexec \\%computername% -s schtasks /change /tn "\Microsoft\Windows\TaskScheduler\Maintenance Configurator" /disable

psexec \\%computername% -s schtasks /change /tn "\Microsoft\Windows\TaskScheduler\Regular Maintenance" /disable

psexec \\%computername% -s schtasks /change /tn "\Microsoft\Windows\TaskScheduler\Idle Maintenance" /disable

Server 2016 and Windows 10

psexec \\%computername% -s schtasks /change /tn "\Microsoft\Windows\DiskCleanup\SilentCleanup" /disable

psexec \\%computername% -s schtasks /change /tn "\Microsoft\Windows\Servicing\StartComponentCleanup" /disable

psexec \\%computername% -s schtasks /change /tn "\Microsoft\Windows\ApplicationData\DsSvcCleanup" /disable

psexec \\%computername% -s schtasks /change /tn "\Microsoft\Windows\WindowsUpdate\Automatic App Update" /disable

If you discover any other scheduled tasks that cause Windows Modules Installer Worker to start running, please do let me know in the comments.

Disable Windows Update Service

If you still experience high CPU utilization from Windows Modules Installer Worker or svchost.exe, try disabling the Windows Update service.

This post describes how to fix the error "This app will now restart to free up more memory" which can occur when using apps such as Netflix on an LG TV after just a few minutes of use. Resolution To resolve the issue, unplug the TV then press the on/off button for 10 seconds.  Wait a further 20 seconds then plug the TV back in and turn it back on. Apps should now run without the error. Edit: The on/off button on my LG TV is directly under the standby light on the bottom of the TV. Edit: I didn't have to do this myself but one person who has left a comment said that clearing all browsing data worked for them.  I have written a post explaining how to do this: LG TV Clear All Browsing History Data .
