Since I originally published my post about fixing Windows 10 updates error 0x800705b4, back in October 2015, I received almost 100 comments on it!! This is awesome, and you’re awesome for taking the time to comment – THANKS! While some comments were simply a “thank you” note for providing a working solution, some actually mentioned other working solutions. As I know it is complicated to find the answers simply by reviewing the comments, I have gathered the solutions into a single list. I hope that either one of the suggested solutions will help you fix the 0x800705b4 error code.

  5. Upgrading windows from Build 1511 to Build 1607 as shared by bett01 in his comment from December 23rd, 2016.
    @bett01 couldn’t not solve the issue, and while all his clients updated before the November fix, they all failed during December. Upgrading his clients build to 1607 solved the issue. Thanks bett for sharing!
  6. Manually update to the latest version of Windows 10 by following this link, then clicking on the “update now” button.
    This was proven to work by Dave Cole in his comment on the original post. Thank you Dave!
