Windows 10: Cannot disable Windows Defender components to repair ownership error

This problem showed up about two months ago, after a Microsoft update. Windows Defender began generating a stream of event error ID:16 - Error while updating Windows Defender status to SECURITY_PRODUCT_STATE_ON. Each error message is stamped with the same Date & Time which makes me think that the Events log crashed.
Found the problem immediately. Of the four Defender related services, three are logged on as Local System but the Windows Defender Antivirus Network Inspection Service is logged on as Network Service.
The problem is that I am unable to stop these services to enable the settings.
List of Defender related services and their status:

Columns:
Name:
Startup type:
Service status:
Is access enabled or disabled: (There is only one user and one Admin account on this desktop ).
Logged on as:
Code: Windows Defender Security Center Service Auto running controls disabled Local System Windows Defender Firewall Auto trying *1079 controls enabled Local System Windows Defender Antivirus Service Auto running controls disabled Local System Windows Defender Antivirus Network Inspection Service Manual running controls disabled Network Service Windows Defender Advanced Threat Protection Service Manual not running controls enabled Local System[/quote] * event ID 1079 is also a logon error for Windows Defender Firewall.
Also tried Windows Club software to stop the services and that didn't work.

Hi Andrew,

If I understand you correctly you are willing to disable Windows Defender from your system. I would like to know few more things to understand the issue in a better way.

• Why are you trying to disable Windows Defender? Are you planning to install any third party security software?
• From where you have followed the steps to disable Windows defender using registry?
• Are you logged in as Administrator?

same task.

• Press Windows key + R to open run box.
• Type services.msc and hit enter.
