When you check on the processes in the Task Manager, you see a specific process called Windows Modules Installer Worker running at very high CPU usage or high disk usage in Windows 10. If that is what you are concerning right now, here’s what you need to know about the process and how to fix and reduce its work load.
Windows Modules Installer Worker High CPU or Disk Usage in Windows 10 Fix
What is Windows Modules Installer Worker?
Windows Modules Installer Worker, also known as TiWorker.exe when it is seen in details, is a service Windows Update relies on to look for new updates from Microsoft database and to install these updates to your computer. When you check for updates for your PC, or when Windows Update runs itself as scheduled, this process will run automatically in the background.
So, it is really not something to worry about. Unless, of course, if the Windows Modules Installer Worker continues to run at high CPU usage or high disk usage endlessly, you can then do something about it.
Fix Windows Modules Installer Worker High CPU
For those who see this process the first time, we would suggest you to just wait it out. It may be installing important modules and updates for your Windows 10. It can take hours to complete depending on how fast is your internet connection.
If it continues to run at high CPU or high Disk usage even after hours of waiting, or if you just want the process to stop right now, you can set the Windows Modules Installer Worker service to manual so that it will only run on demand.
It’s worth noting that if you try to terminate Windows Modules Installer Worker process by clicking End Task in task manager, it will just go off a little while and will come back a minute or two later. So, setting the service to manual is the only way to completely stop it from running without your consent.
However, we would not recommend you to do this as this will stop Windows Update from running automatically. When the process is set to manual, you will have to check for updates manually through the Windows Update interface in order to receive latest updates. You may want to try running the Windows 10 Update Troubleshooter first to check if the problem originated from Windows Update service itself. If nothing works to solve the Windows Modules Installer Worker high CPU and disk usage issue, you can then consider to stop the service entirely.
The major reasons of people wanting to stop this process is because it is running and eating up battery juice regardless if you are in charging mode for laptop users. If that’s the case, setting Windows Update to manual can help to fix the issue.
Setting Windows Update to Manual
To set the Windows Modules Installer Worker service to manually and only run on demand, follow the steps below.
- In Windows 10, go to start menu.
- Search for services.msc and open it.
- In the Services window, look for Windows Modules Installer from the list of services and double-click on it.
- From the Windows Modules Installer Properties window, set the Startup type to Manual instead of Automatic.
- Click Apply, then OK.
- Optionally, you can also terminate the process immediately by clicking on the Stop button if you want it to stop right now.
- Next, in the services window again, look for another service called Windows Update and double-click on it.
- In the Windows Update properties window, set the Startup type to Manual.
- Click Apply, then OK.
- Close the Services window and restart your PC.
On the next startup, access to your task manager and check if the Windows Modules Installer Worker high CPU usage or high disk usage in Windows 10 issue is resolved.
This method should stop automatic Windows Update entirely, thus, also preventing the Windows Modules Installer Worker process from running. If you’ve done this, be sure to regularly check for updates on your Windows 10 as it will no longer be checking for you automatically after the change.
