Shane,

Using Windows Home (v1803 64-bit), post running Windows Repair (v4.3.0) All Repairs,
Windows Defender has been disabled.  I am unable to re-enable it.  I am hoping to avoid a clean install.

I have attempted to resolve the issue with the approaches listed in:
 - https://www.tweaking.com/forums/index.php/topic,2732.msg18391.html#msg18391
 - https://www.tweaking.com/forums/index.php/topic,3563.msg25528.html#msg25528

All to no avail.  Please refer the attached pictures are you able to assist?

Thanks
Shannon

As there have been other problems reported about WD and the repair program, I'll pass this onto Shane.

I'm not sure if you have used the registry restore option in the repair program to see if that resolves.

If you are using Win 10 Home so don't have gpedit then you can enable it by opening a Command Prompt (Admin) or Powershell (Admin) and entering this cmd - you can copy & paste it to the cmd prompt, but create a restore point first.

dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\{{Microsoft-Windows-GroupPolicy-ClientExtensions-Package".mum}}

To access GPE press the Windows key+r then type gpedit.msc and press enter.

Should you need to take ownership of a file, use the batch file in this article to add Take Ownership to the right click context menu.

Well I got that cmd from a Windows help article, but try the batch file in this article which includes instructions for its installation.

I used a batch file from another article for mine but was unable to get the page to open, so posted that cmd instead.

While you aren't getting the message that this article refers to but if you have managed to include the GPE in your version of Win 10, see if the steps in this article will help.
