  I know I'm almost a year late, but I have a fix - the only one that has worked for me.
  The issue I had was that I needed to delete the "Security Health" folder (Windows/Sysem32). Of course I couldn't delete it because the permission was locked to 'SYSTEM'. What you need to do is make your main log-on account have privileges to access files in the same way as SYSTEM does. Once you've enabled the permissions, you can delete the folder. Once the folder is deleted, restart your PC and run Windows Update after. It will download the latest version of Windows Security and BOOM. It will now be working.
  
  Some sort of bug locks the Security health folder, and that seems to stop it from working. Once you get rid of this problematic folder, you should be golden.
  
  Here's a vid of how to delete a file/folder when it's locked by "SYSTEM":
