Problem with the Windows Modules Installler Service or the TrustedInstaller.exe binary.


First, attempt to simply (re)start the Windows Modules Installer Service.

  1. WIN+R, services.msc [enter].
  2. Scroll down to the Windows Modules Installer Service.
  3. Ensure the service is not set to Disabled. It should be set to Manual.
  4. Start the service.
  5. Try running Windows Update again.

If the service is not installed or will not start, or you still get an error, find another computer running the same operating system, version, and language as yours.

  1. Log onto this second system with administrative credentials.
  2. WIN+R, regedit [enter].
  3. Browse the registry to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TrustedInstaller.
  4. Right-click the subkey, click Export, and save the file as trustedinstaller.reg.
  5. Copy this file to the problem computer.
  6. Double-click the reg file on the problem computer and click Yes to merge the file with the registry.
  7. Reboot.
  8. Try running Windows Update again.

If this still does not resolve the issue, you can restore the binary file.

  1. On the second system, browse to the c:\windows\servicing directory.
  2. Copy TrustedInstaller.exe to the problem computer’s desktop.
  3. On the problem computer, move the TrustedInstaller.exe file to the c:\windows\servicing directory. If that errors, make sure you have Full Control rights to the folder. At an administrative cmd prompt, you can use these two commands.

takeown /f c:\windows\servicing icacls c:\windows\servicing /grant administrators:F

  1. After you have replaced the binary on the problem computer, reboot.
  2. Try running Windows Update again.

Error 0x80070424 from the winerror.h file indicates “The specified service does not exist as an installed service.” If you encounter this error doing things that do not involve security components of Windows, it is an indication that some other service that your action depends upon is stopped, missing, or corrupt. Check the appropriate service(s) to confirm they are enabled and functional.
