Windows Modules Installer Worker has a reputation for its excessive CPU usage on Windows 10 systems. If your PC runs on Windows 10, you might have seen this process several times already. Well, you are not alone if you see that – there are plenty of other users experience the same issue. If you continue reading this article, you can learn how to fix it easily.
Introduction to Windows Modules Installer Worker
In simplest terms, Windows Modules Installer Worker is a Windows Update Service. This specific service looks for potential new updates and installs related to your Windows OS. That means Windows Modules Installer Worker starts to run when the OS checks for or installs a Windows update.
Why does this process take high CPU capacity?
The most frustrating thing about Windows Modules Installer Worker is that it takes a significant CPU capacity. To add more frustration to it, this process can emerge randomly, and it is just a “normal” process. In other words, you can expect Windows Modules Installer Worker more than once when you use Windows 10. That’s the bad part of it.
The good thing about it is that this process is supposed to stop automatically after running for some time. Once the process is completed, your CPU and disk resources will be released for other purposes. At the completion of the update, it will not appear on your Windows Task Manager. The duration the process takes to be completed will depend on a couple of aspects. That means aspects like the speed of the CPU, and the storage capacity of the computer will determine it. In addition to that, the number of updates the system has to run will affect the time it takes.
Is it possible to disable this process?
It is true that some individuals may advise disabling the process straightaway to get rid of it. It is also true that disabling this process can stop excessive usage of CPU. However, disabling the process may not be the smartest approach for any Windows user. That is because your Windows OS becomes incomplete and even insecure if it doesn’t get updates as required. So, you must have this in mind when disabling the windows installer.
On the other hand, some individuals may even recommend setting the network with a meter. That means they advise you to apply a restriction on the network connection as a solution. This will prevent some updates from installing. Also, it will prevent the Windows modules installer process from getting activated. However, the downside of this move is that it doesn’t install critical security updates as well. As you can easily realize, preventing security updates from installing is not a very smart measure. That makes you vulnerable to various malware attacks, including viruses and ransomware. So, we should tell you that preventing essential security updates is a risky approach.
There is the option of installing the updates manually if you prefer. However, the Windows modules installer worker will still run once the manual update is done. So, the most recommended approach is to allow updates to be installed.
Is Windows Modules Installer Worker a virus?
As we have mentioned above, the Windows Modules Installer Worker is a part of Windows. There is no malware with the same name as of this writing. Although there are many viruses that disguise themselves under other system files, that’s not the case with this process. Nevertheless, if you still suspect that your computer is under a malware attack, go ahead and scan it. You must have a good malware scanner installed on your computer and keep it updated. So, Windows Modules Installer Worker is not a virus, and it is a system process. You don’t need to worry about it but should be prepared to compromise some system resources time-to-time.

- Once the window is opened, you should follow the path below. HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > NetworkList > DefaultMediaCost
- Then, you should perform a right-click on the option called “DefaultMediaCost” and then choose “Permissions” as well.
- You can now click on “Add.” Type the username and click on the option labeled “Check Names.”

Those are the two options we have to present to resolve Windows Modules Installer Worker. You can try one option after the other if the first option doesn’t work.
Windows Modules Installer Worker is not a virus at all. It is just a system process that becomes activated when the system starts to work on an update. However, it can become problematic at times, as mentioned in the article. If you face such annoyance, you can try the solutions we have mentioned above.
