If the other discussion was preformed then both updates KB3020369 &
KB3172605 have successfully installed.
Then I would also reset the update system and services afterwards
Use Option 3 here for an automated way to do this,

I personally prefer this one it's much better just a little more user interaction,
Use Option 2 on the list after right clicking it and select run as administrator

Download it to your downloads folder
Right click it and select Extract all to the downloads folder.
Then right click ResetWUEng and select run as administrator
Follow the rest of the prompts
Press any key to continue
Type 2 for that Option on the list and the Enter key to reset update services..
Press y for Yes and then the Enter key I believe twice
After it has completed
Type 15 for that option and the Enter key to restart the machine.
Should say will restart in 60 seconds save your work.... press any key to continue.
After restart go to windows updates and manually check for updates shouldn't take a few minutes.

Please try the above as well
