What is Windows Modules Installer Worker?
Also known as TiWorker.exe, the Windows Modules Installer Worker is part of Windows, specifically of the Windows Update Service. It’s actually this process that is responsible for checking and installing your Windows updates.
To be more precise, the TiWorker.exe enables installation, modification, and removal of Windows updates and optional components according to the official description of this service that automatically runs in the background when you click the Check for Updates button or when you want to uninstall an update for that matter.
Since Patch Tuesday is already a tradition that Microsoft put in place, you might be using this service a lot without even know it.
Where do I find TiWorker.exe?
You can simply locate it by opening up the Task Manager and check the Processes tab for Windows Modules Installer Worker. More information, including its file name, are to be found on the Details tab.
Why does TiWorker.exe use so much CPU?
The process should simply run in the background and deal with your updates, however, more often than not, it does not work so smoothly.
In fact, it is one of the most notorious CPU-gulping system processes that is widely known to take up a large percentage of your CPU and disk resources. Mostly, it occupies more than 50% of CPU, but in some rather grave cases, it can create up to 100% disk usage.
This happens due to corruption generated issues typically and it’s because of data and files corruption that the WMI Worker process can make your PC run slow, freeze or crash completely.
Is it safe to disable TiWorker.exe?
It’s actually common advice to stop and disable the service, but it is also not the way to go and we would not recommend you to do so.
Since the Windows Modules Installer is a native Windows process that is specifically designed to handle the proper installation of updates, you might end up causing more damage than good by disabling it.
Keeping your OS up to date is essential and you do not want to miss those critical patches or security updates that stand between your system and all the mean malware and viruses that roam the internet these days.
