Windows Modules Installer Worker

If you notice that your computer suddenly sounds like it’s about to hit warp-speed and has, unbeknownst to you, turned into an induction cooker. Then try running Task Manager, and see if the “Windows Modules Installer Worker” is running. As it’s quite likely that this process, occasional alias TiWorker.exe, is to blame. If this is the case don’t worry, Windows OS is working as intended.

Windows Modules Installer Worker, what is it?

Microsoft designed the Windows Modules Installer Worker to help users easily manage their Windows updates and its various elements. The new smoother experience on the Windows 10 OS, means that updates are now installed automatically in the background. Of course, users are still free to manage features and updates manually, and the Windows Modules Installer Worker will kick in automatically to help you with the process.

You can check if the Windows Modules Installer Worker is running by opening the Windows 10 Task Manager and looking out for the Windows Modules Installer Worker, which is called TiWorker.exe on the Task Manager Details tab.

Microsoft regularly releases patches on the second week of each month on a Tuesday, an event that is unofficially known as “Patch Tuesday”. That being said, the company has been known to release the odd update outside of this timetable.

Some updates will ask you to turn off your computer and restart once they are completed, though this is not always necessary. In any case, the updates process is relatively unobtrusive, and won’t get in the way of your work.

Does it really need all of my CPU?

If you notice that the update process is using up a lot of resources, it’s quite likely that your computer has just downloaded a significant update from Microsoft. Unfortunately, the occasional spike in CPU usage, as a result of the Windows Modules Installer Worker, is a part of the Windows 10 OS experience.

But don’t worry, though these processes can be resource intensive, they are over relatively quickly. As such, your CPU should be back to normal in double time. Of course how long exactly this will take is something we cannot say for sure, and major updates will take longer.

Can I turn it off?

Windows Modules Worker

Some people recommend that you turn off the Windows Modules Installer, but this is terrible advice. Turning off the Windows Modules Installer will mean that Windows will be unable to install updates on your computer properly.

Others advise you to change the network connection on the PC to “metered”. This will stop Windows 10 from running updates on its own, but this will put your computer at risk, as it also means that you will be missing out on possibly vital security updates.

Missing out on updates is not something we would recommend, the world is full of dangerous malware, such as the famous WannaCry ransomware. WannaCry managed to cause untold damage and spread like wildfire, even though a patch for the exploit was released many months before the virus first appeared.

You can, of course, install updates yourself, but even if you do things the old-fashioned way, the Windows Modules Installer Worker will run automatically after an update. To be honest, leaving the TiWorker.exe process alone, is not only the easiest thing to do but also the smartest. Microsoft decided that this is how it would implement updates and keep its users safe, and if it’s good enough for Microsoft, it’s good enough for us.

Is it dangerous?

Windows Modules Installer Worker is an integral part of the Windows OS experience. To date, there have been no cases reported of malware trying to sneak onto PCs by pretending to be the Windows Modules Installer Worker or TiWorker.ex. That said, if you are concerned, it certainly won’t do you any harm to see if something’s amiss.

What to do if you suspect something’s wrong

If there is a reason to suspect that something may be wrong with the Windows Modules Installer Worker, help is at hand and there are a few easy fixes you can try yourself. Don’t worry these measures will only work if something is wrong, they won’t mess up your computer if everything is as it should be.

The Windows Update troubleshooter is a great little resource that can quickly sniff out any problems you may be having with the Windows Update. Assuming your OS is Windows 10, simply head to your Settings, and run the Windows Update, in the Update & security section. This will launch the troubleshooter scan, which will check your PC for possible issues. Once the scan is finished, it’s just a question of approving the fixes it suggests, and hopefully, everything should be as good as new.

If that doesn’t work, or no issues were found, then try scanning with SFC or DISM. These programs will quickly confirm whether any vital system files have gone AWOL on your computer, or are corrupted.

It may also be a good idea to have a look at some of the free tutorials and other resources, that are available on the Microsoft website. These tutorials are a handy resource, and can help you gain the know-how to ensure that your Windows Update is working as intended.

Should none of these steps help resolve your issue then restoring your PC to its factory settings, and implementing an OS reboot will definitely do the trick.
