  1. Here was my resolution: For some reason or another there was a Registry setting that was preventing the servers from connecting to the update service.

    Steps to resolve:
    – Open Registry Editor on the server
    – Navigate to: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\AuthRoot\AutoUpdate
    – Delete “RootDirURL”

  2. In my case it’s saying the database is corrupted and also the required apps isn’t installed. How to fix this and because of this I can’t launch Start button. Thanks.

  3. I have tried to install several different updates and everything I have tried fails. I have 2 updates pending that neither one will install because of quote missing files. I have went through the whole process of trying to delete the downloads folder I’ve went through other processes trying to figure out how to fix the missing files including the Windows Update troubleshooter which says that it finds things in fixes it but it doesn’t. I’ve also went through so are other processes using the command prompt to try to find and fix errors, using the SFC and DISM. All came back good. I’ve used something called Reset_Reregister_Windows_Update_Components bat file, which says several things are missing or not assess-able. I have even downloaded the updates from the microsoft update catalog web page and both times I tried to install them, it said updates were not installed. Any help here would be amazing because I do not want to have to restore my computer back to factory and lose everything that’s on it.

    those are the 2 updates I’m trying to install they keep failing. Is there any way to force install them or to delete them out of my Windows Update so my system won’t keep showing that I have security errors that need to be fixed but I can’t fix them?
