    Windows Modules Installer does not exist in Services.


    I was trying to run sfc /scannow, which gave me:
    Code:
    Windows Resource Protection could not start the repair service.
    I figured through google that it's the problem of the Windows Modules Installer,
    and the problem seemed to be the default setting of its startup type;
    however, when I went into services.msc, Windows Modules Installer did not even exist.

    I then went to c:\windows\servicing in order to check whether TrustedInstaller.exe existed, which it did, so I tried running it, but nothing happened.

    Any thoughts?

    mandu1021,

    Welcome to the Forum!

    Please right-click the white Window on the bottom left of the screen.
    Select: Command Prompt(Admin)

    At the Command Prompt, copy/paste (with mouse), or, type: sc config trustedinstaller start= auto
    Press: Enter
    A Success message should appear.

    Next, at the Command Prompt, enter: net start trustedinstaller
    A message stating that the service was started should appear.

    Now try the sfc /scannow command.

    both of those did not work, unfortunately.

    Code:
    sc config trustedinstaller start=auto
    [SC] OpenService FAILED 1060:
    
    The specified service does not exist as an installed service.
    Code:
    net start trustedinstaller
    The service name is invalid.
    
    More help is available by typing NET HELPMSG 2185.
    Code:
    NET HELPMSG 2185
    
    The service name is invalid.

    sc config trustedinstaller start= auto
    Please try it with a space after the equal sign.

    It returns the same thing:

    Code:
    sc config trustedinstaller start= auto
    [SC] OpenService FAILED 1060:
    
    The specified service does not exist as an installed service.

    Sorry, my fault!! It is altogether missing.

    Make sure that the TrustedInstaller.exe file exists in the %WinDir%\servicing folder.
    If this file is missing you can try to restore it from your Windows 10 installation media.

    Go to the Automated Restore:
    Windows Modules Installer - Windows 10 Service - batcmd.com

    I then went to c:\windows\servicing in order to check whether TrustedInstaller.exe existed, which it did, so I tried running it, but nothing happened.
    It exists, but it doesn't appear on the services.msc.

    RestoreWindowsModulesInstallerWindows10.bat did not work - that .bat file is simply:
    Code:
    sc config TrustedInstaller start= demand

    mandu1021,

    Let's give this a whirl:

    Open Command Prompt (Admin) again.
    Once at the Command Prompt, type:
    cd c:\Windows\servicing
    Press: Enter

    At c:\Windows\servicing> type in and Enter:
    TrustedInstaller.exe
    Hopefully, this will start the executable in the background.

    Next, type in and Enter:
    sfc /scannow
    You should no longer received the error message as before.
    It will also make you restart your computer if it finds anything wrong.

    Now, press the Windows key and the R key at the same time.
    Type in:
    msconfig
    At the System Configuration console, click on the Services tab.
    If the list of Services is not in alphabetical order, double click the Services column.
    Look for the Windows Module Installer, it should now be on the list.
    If it is not started, right-click and select: Start


    How did it go?

    If still no joy, we may need to replace the TrustedInstaller.exe in C:\Window\Servicing, or do a repair install.

    Yeah, so it still throws the same error:

    Windows Resource Protection could not start the repair service.

    Even if I try to run TrustedInstaller (double click, admin, command prompt etc...), it won't do anything - nothing will appear on the Services.

    Thank you for trying to help, by the way.

    mandu1021,

    My pleasure, that i what we are here for.

    Unfortunately, this issue is not a simple thing to solve.

    At this stage it does not appear that engaging in any more procedures will solve the issue.
    You need to consider a Repair Install.

    The following provides guidance on how to do so:
