Answer 1

Hello William B,
Thank you for posting in Q&A forum.

Do you mean you want to disable "Windows Modules Installer" service below?

If so, before proceeding, please note that the Windows Modules Installer service (commonly known as TrustedInstaller) is an essential system component that enables Windows to install updates and modify system components. Disabling it permanently may lead to issues with Windows updates, system patching, and even the installation of some new software. Microsoft designs Windows to re-enable this service when necessary to maintain system stability and security.

If you still wish to disable it permanently, here are considerations and methods:

Windows Update and certain system maintenance tasks require the Windows Modules Installer. Even if you manually set its startup type to Disabled, scheduled tasks or update processes may reconfigure it to run when needed.

Method1: Changing the Service’s Startup Type via Services Console

1.Press Windows + R, type services.msc, and press Enter.

2.Scroll down to “Windows Modules Installer.”

3.Double-click the service, then set “Startup type” to Disabled.

4.Click Apply and OK.

Please note: Even after doing this, Windows may re-enable the service when it needs to apply updates.

Method2: Editing the Registry

Warning: Modifying the registry carries risk; back up your registry or create a system restore point first.

1.Press Windows + R, type regedit, and press Enter.

2.Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TrustedInstaller

3.Locate the “Start” DWORD value.

4.Change its value data to 4 (which means Disabled).

5.Close the Registry Editor and restart your computer.

Keep in mind: System updates or Windows maintenance routines may overwrite this value.

Also, some tasks in Task Scheduler might trigger the service to start. You can review the scheduled tasks (using Task Scheduler) for any entries related to Windows Update or Module Installer and disable them. However, disabling these tasks can adversely affect how Windows maintains its updates and overall security.

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

Best Regards,

Daisy Zhou
