    Some DLL Files are missing or corrupted in Windows Defender anti-virus

    I decided to run command prompt with run as administrator right and you will see 5 missing DLL files below. Is that a possibility that I couldn't run Windows Defender as my anti-virus program in my desktop but Widnows Defender firewall is running with no problem?

    regsvr32 wuaeung.dll -- missing
    regsvr32 wucltui.dll -- missing
    regsvr32 softpub.dll -- good
    regsvr32 wintrust.dll -- good
    regsvr32initpki.dll -- missing
    regsvr32 wups.dll - good
    regsvr32 wuweb.dll -- missing
    regsvr32 atl.dll -- missing
    regsvr32 mssip32.dll -- good

    Here is one example of missing dll file.


    ( X ) The module "wuweb.dll" failed to load.

    Make sure the binary is stored at the specified path or debug it
    to check for problems with the binary or department .DLL files.

    The specified module could not be found.

    So that mean that there are missing DLL Files in Windows Defender which cannot run in my operating system of Windows 10 Pro 64-edition? Can this be done to repair or have to reinstall or what?

    Thank you,

    Have you ran sfc /scannow yet? Also have you done dism? Use DISM to Repair Windows 10 Image | Tutorials Follow these steps. Replace the .dll file with the ones that are missing to uninstall and install.

    1. Click the Start button.
    2. Type "command" in the search box... DO NOT hit ENTER yet!
    3. While holding CTRL-Shift on your keyboard, hit ENTER.
    4. You will be prompted with a permission dialog box.
    5. Click Yes.
    6. Type the following command: regsvr32 /u wuaueng.dll.
    7. Hit ENTER. This will UN-REGISTER your file.
    8. Type the following command: regsvr32 /i wuaueng.dll.
    9. Hit ENTER. This will RE-REGISTER your file.
    10. Close the command prompt window.
    11. Re-start the program associated with wuaueng.dll error.

    Windows 10 has a nice utility to look for missing or corrupted system files and make corrections.

    Check out this tutorial: Run SFC Command in Windows 10

    Hope this helps!
