Windows Modules Installer Worker High CPU Server 2012, 2016, 2019 & 2022

This post describes how to stop the Windows Modules Installer Worker process when it uses high CPU on server 2012, 2016, 2019 and 2022.  On a live server, I would leave this running however on a test virtual server, it can slow down the entire machine and be a real pain!

To stop the process:

1. Open Windows Task Manager

If I'm using one of my Windows Server 2012 R2 or Windows Server 2016 virtual machines and it starts running really slowly, the first thing I check is Task Manager.

2. Check if the Windows Modules Installer Worker process is using 99% CPU

If the Windows Modules Installer Worker process is using 99% CPU, it's possible that the machine has started maintenance.  This can often happen with virtual machines that are only powered on occasionally.


3. Check if Windows Maintenance is in progress

To check if maintenance is running, open the Control Panel, go to Action Center then expand Maintenance.


Control Panel Action Center

4. Press Stop maintenance

Press the Stop maintenance hyperlink. After a minute or so, you should notice the Windows Modules Installer Worker process stops using the CPU and the performance of your machine vastly improves!

5. Stop Windows Update Service

If you're still experiencing high CPU utilization (e.g. from svchost.exe), open Services (Start > Run > services.msc), and stop the Windows Update service if it's running.

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 . Edit: A few other people have also suggested turning off quick start in settings (and if it's already off, turn it on then off again).  I have written a post explaining how to do this: LG TV turn off Quick Start in settings Related Posts -  LG TV delete/remove/hide ch
