This problem continues into 2019, and, to my experience, none of the above answers are effective in the present day. At great length, I have been able to correct this issue with my Dell 3135 after a factory image restoration and installing update KB4504418 followed by KB3172614 & then KB4512488. Lots of helpful clues to be found in this thread. I did stop the Windows Update service before applying these updates, & I did apply them using an Administrative Command terminal, entering:
start /wait "" "%SystemRoot%\system32\wusa.exe" "C:\full\path\to\Update.msu" /quiet /norestart
as described in this very expert advice. (For those less savvy, you must replace the above path, "C:\full\path\to\Update.msu", with the explicit full path to the update module.
It is worth mentioning that I was unable to enact any of these updates in Safe Mode as advised in an earlier solution.
