Since several days my Windows 10 won't install the update named KB3122947 or any other newer updates. I always get the error 0x80070643. What can I do to solve this issue?

The fix was to manually force the system to install the update.


  1. Verify that Windows Update has downloaded - but not installed - the update. These are two different things. In your File Explorer, enable Hidden items under View and go to


    Check if either windows10.0-kb3122947-x86.cab or windows10.0-kb3122947-x64.cab are present (Depending on which Windows type your have)

  2. Right-click on your Start button and choose Command Prompt (Admin). Paste and execute the following command corresponding to your Windows type

    Windows x86 (32-bit)

    dism /online /add-package /packagepath:C:\Windows\SoftwareDistribution\Download\b0a5da1b24245bc4237166e09bae92da\windows10.0-kb3122947-x86.cab

    Windows x64 (64-bit)

    dism /online /add-package /packagepath:C:\Windows\SoftwareDistribution\Download\c4a1b8896ce9fbfea96c1ee6890d52a5\windows10.0-kb3122947-x64.cab

  3. If you see the message The operation completed successfully. restart your system and you're done.

  • This in theory could be used on any update that fails in a similar way. You just have to determine what the .cab file is for the update. – Ramhound Dec 9 '15 at 13:22
  • Could someone with a x64 Windows please confirm that the subfolder c4a1b8896ce9fbfea96c1ee6890d52a5 is really a different one on x64 then on x86? – nixda Dec 11 '15 at 21:50
  • This solution is failing for me with the same error. Checking, I find that the kb has not downloaded. – Remou Feb 25 '16 at 16:30
