failed to install KB4056892

I have a Elitebook 2560p and I have a clean install of Windows 10 on it (not officially supported by HP but it works fine without third party driver apart the ones that Windows auto download from Windows update). I have a problem with KB4056892 it fails with the error code 0x800f0922. The previous cumulative security patch had the same effect (KB 4054517). The update begin to install; then I see a message that there is a problem and "revert all changes" and I see in Windows update that the update has failed. I have tried to obtain a detailed explanation about the failure following this: https://support.microsoft.com/en-us/...0-version-1607 but I am not able to interpret these logs. Do someone has a clue of what is wrong?

Please try below programs one at time.
