Windows Module Install Worker is a core Windows compnent that downloads and install Windows updates. In Windows 10 or higher, Windows updates cannot be  disabled (at least not easily) due to security concerns.

If your experience slow performance on Windows 10 or Windows 11 and notice that Windows Modules Installer Worker is having high disk usage, try the following:

Run the command SFC /Scannow from an elevated command prompt to check that the operating system files are intact.

You can try using DISM image repair to check and restore your PC’s health.

DISM /online /cleanup-image /restorehealth

If that does not fix your issue, download and run the Windows Update reset tool, available on Github.

Create a folder on your hard drive named script then create a text file named ResetWUEng.cmd

If you cannot see the extension properly, click on the view menu from any folder.

Select options –> change folder and search options

From the view tab, uncheck hide extension for known file types and apply.

Now right click on the file and remove the .txt extension so that the file is named ResetWUEng.cmd only.

Copy and paste the text from the script by ManuelGil into the text file and save it. It should look something like this.

From an elevated command prompt, enter cd c:\script to take you to the location of the file.

image

Enter the command .\ResetWUEng.cmd to run the script.

Run options 2 and 3 in the script then restart your PC.
