  • Run the following command: "proxycfg.exe -u". 
  • Start Automatic Update Service - "Net start wuauserv".
  • Force update detection and see if that works.

2. Re-create the Datastore -

  • Stop Automatic Update Service - "Net stop wuauserv".
  • Rename/delete "%Windir%\SoftwareDistribution" folder. 
  • Start Automatic Update Service - "Net start wuauserv".
  • Force update detection and see if that works.

3. Try to force install WUA.

I call it usually a totally bad luck) Yes, I successfully fixed one error, but another error
Windows was already waiting for me. Not that it was so difficult actually, just had to make some effort and download msvcp140.dll missing msvcp140.dll missing but as I read later in the sources, this error is quite common and many users like me were forced to search for dll files.
Now they are available, I'm glad to share it, in turn, to save you from a long searching.
