Set Windows Modules Installer’s Startup Type to Manual
Windows Services (also known as services.msc) can modify how Windows services run on your system. You can change a service’s settings for security, troubleshooting, and performance-related reasons.
You will need to access the Windows Installer service, which enables installation, modification, and removal of Windows updates and optional components. If this service is disabled, installation (or uninstallation) of Windows updates might fail.
To access Windows Modules Installer, type «run» in Search and click the «Run» result.
In the Run dialog box, type «services.msc» and click «OK» to open Windows Services.
Now, scroll down through the services list to find the «Windows Modules Installer» service. Right-click it and select «Properties» from the drop-down menu or simply double-click the Windows Modules Installer service.
Ensure that «Startup type» is set to «Manual» and click «Apply» to save any changes made.
You may also wish to apply the same settings to the Windows Update service. Find the «Windows Update» service in the list, right-click it and select «Properties» from the drop-down menu.
Ensure that «Startup type» is set to «Manual» and click «Apply» to save any changes made. Restart your computer.
These changes to your system should stop Windows Module Installer Worker service issues. However, once the Windows Update service is configured in this way, you will have to check for updates manually.
