Should You Fix Windows Modules Installer Worker High Usage ?

The straight answer is no, as it is a systematic process to make sure your Windows 10 system is up to date. You should only look into fixing this if it is out of the ordinary and the system usage never goes down over time.

If automatic updates have been turned off for a while, eventually your computer will be updated if the update is a must-have. In this case, the updater will go through the backlogs and download and installs any updates that might have been pending for your system.

To make sure the windows modules installer worker is working as it should follow the below-mentioned steps to determine that and see if it needs to be resolved.

Restarting The Windows Update Service

Sometimes the Windows update service can freeze and become unresponsive. In this case, you can restart the update services.

Hit the “Windows” + “R” key together on the keyboard.

Enter “services.msc” and hit the enter key.


Find the “Windows Update” from the list. If you have automatic updates enabled, the startup type is usually set to “Manual(Trigger Start). This means any other operating system events can trigger this.

Right-click on “Windows Update” and restart the service.

Now lets, update the Windows manually and install any updates that are pending.

Go to search and search for Windows Update.

Click on “Check for Updates” to manually check for any available updates to be installed.

If the update says “You’re up to date” this means the windows modules installer worker should not be using that many resources since there are no updates available.


Give it some time to complete whatever it is doing if this is the case.

Run The Windows Update Troubleshooter

If your Windows is up to date but the usage from these services is still very high, you should run the Update troubleshooter to confirm there are no issues with the update tool.

Go to Start and search for “Troubleshoot” and open Troubleshoot settings.

In the window that pops up, click on “Additional troubleshooters” and open “Windows Update”.


Click on “Run the troubleshooter”, the troubleshooter will look for any tasks that are pending or should not be running in the first place.


If the troubleshooter does not identify any problems, that also suggests that the updater is running as scheduled and should be left to complete its task.

Is The Windows Modules Installer Process A virus?

No, it’s not a virus. As explained earlier it updates your operating system constantly unless you have manually paused it. You should only be concerned if the users do not seem to fluctuate and are constantly showing high usage.

Do not Edit Registry or Disable Windows Update

There are a lot of blogs that suggest you completely turn off automatic updates or even edit the registry. I highly suggest you not to do so, as your computer will be missing quality updates and patches that keep your computer safe offline or online.
