1. Stop and disable the Windows Update service

As mentioned earlier, the issue is mainly caused because the program is looking for Windows updates or installing them.

Hence, the best way to fix the issue is to stop and disable the Windows update service. By doing so, Windows will no longer be able to look for any updates or install any updates.

To do so, you have to follow the below steps:

  • First, from your keyboard, press Windows Key + R to launch the Run box.
  • Type down, services.msc and press enter.

However, if this folder is corrupted, it can lead to a bunch of issues, and Windows Modules Installer Worker is one of them.

Luckily, deleting the folder will not put your PC at any risk. Also, Windows will automatically create a new folder with the same name when a new update is found.

To delete the folder, you have to follow the below steps:

  • First, disable the Windows Update service by following the first method.
  • Go to File Explorer and navigate to the C:\Windows path.
  • Over here, look for the SoftwareDistribution folder and right-click on it.

Then reboot your computer, and it should fix the issue for you.

3. Restart Windows Update Service

A simple restart can often fix the issue. All you have to do is restart the Windows update service (from the first method) and see if it works.

To restart the service, you have to press Windows Key + R to bring the Run box. Then type down services.msc and press Enter.

4. Use Windows Update Troubleshooter

You can also try running the Windows update troubleshooter to diagnose the problem. I know that troubleshooting doesn’t work in most cases.

But there is no harm in trying it out. Also, maybe it will tell you what is causing the issue, so you can look for further solutions.

You can access the troubleshooter by going to Control Panel > Troubleshooting > Select View All from left panel > Windows Update.
