  1. I have tried to install this update at least 6 times and gone through all of these ‘fixes’. Nothing works the system fails to update and the Update History is empty so I have NO idea what is wrong. This is just one bad update and I am at a loss as to what to do about it.

  2. Thx so much for writing this – I did the dism + sfc route, plus disconnecting literally everything from my hp spectre x360, and running the update manually from within the settings panel and just sitting staring at it through the ~30min install process, and that worked. Much appreciated!

  3. I tried all this and none of it worked. I finally decided to download the latest windows 10 release and do a clean install. The updates then completed with no more problems.

  4. CONEXTANT Driver causes the installation to get stuck. Simply Uninstall any conextant driver using device manager and reboot. Installation will run smoothly
