When starting the computer, if the computer fan becomes hot for no reason check out Task Manager and you will see “Windows Modules Installer Worker” that uses a lot of CPU and disk resources. This process is also known as TiWoker.exe, which is part of the Windows operating system.
What are Windows Modules Installer Worker?
As described by the service of this process, Windows Modules installer Worker enables installation, modification and deletion of updates and options.
Windows 10 will automatically install the operating system updates through Windows Update, so this process will only install updates in the background. However, if you uninstall the update or add or remove an optional Windows feature, the Windows Modules Installer Worker process will need to perform some other tasks.
One thing to note is that the Windows Installer Worker process is on the Processes tab, but its TiWorker.exe file is displayed on the Details tab.
Microsoft releases an update on “Patch Tuesday” every second Tuesday of every month. They can also release updates on other days, if needed. If the process is using a lot of CPUs, it’s likely that your computer has just downloaded new updates from Microsoft.
You may or may not have to restart your computer to install these updates, but Windows will work a lot in the background so that you can continue to use your computer while installing the update.
Why is it using too much CPU?
Running Windows Modules Installer Worker occasionally uses a lot of CPU on Windows 10 is normal phenomenon.
If you allow it to run, the process will finish and stop using the CPU and disk resources after the update. The Windows Installer worker process terminates and it will disappear from the running processes in the Task Manager. Run time depends on CPU speed and computer memory as well as the number of updates to be installed.
Should this process be disabled?
Some people recommend that you disable the Windows Modules Installer system service to prevent this from happening. However, this will prevent Windows from installing updates correctly, so you should not disable this process.
Similarly, others may recommend setting up a Metered Connection network connection, which will prevent Windows 10 from automatically downloading and installing updates. This will prevent the Windows Modules Installer from running, but your computer will not install important security updates to protect your computer from malware such as WannaCry ransomware. Preventing an out-of-date operating system is dangerous and you should not do that.
You can install the update manually, however, the Windows Modules Installer Worker process will run after performing the manual update. It is best to leave the TiWorker.exe process running sometimes, this is how Windows installs the updates.
Is it a virus?
This process is part of Windows. We have not seen any malware reports tampering with the Windows Modules Installer Worker or TiWorker.exe process. However, if there is any doubt you can run an antivirus program.
If you see the Windows Installer Worker process running for hours or maybe you see it running too often, then you can take some steps to troubleshoot it. This will not help if the process is only running for normal reasons but can fix problems with Windows Update and the Windows operating system can cause problems with the Windows Modules Installer Worker service.
The Windows Update troubleshooter can find and fix problems with Windows Update. To run it on Windows 10, go to Settings> Update & security> Troubleshoot> Windows Update> run the troubleshooter. Apply any solution that the troubleshooter suggests.
