    None of above methods didn't work for me.

    After a little bit of searching, I have finally found the solution.

    1. Open Registry Editor and find key HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate
    2. If value for DisableWindowsUpdateAccess is 1, modify it to 0.
    3. Restart Windows Update service
    4. Retry Windows Update
    5. Voila! WU is working!

  • Every one of those updates including the service pack update is useless, because the second i try to install any of them the first thing it does is come up with "searching for updates on this computer" and just hangs at that stage which is the whole problem im trying to fix with the automatic updates. I can't install any of them for that reason
