Cannot change the permissions for a registry key to fix DCOM error Event ID 10016

Looking at the event viewer, when windows starts. I see there is a DCOM error (Event ID 10016) the seems to be about the DCOM CDP service.

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 
{8D8F4F83-3594-4F07-8369-FC3C3CAE4919}
 and APPID 
{F72671A9-012C-4725-9D2F-2A4D32D65169}
 to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

I followed a few posts to try and correct the error but while I could change the ownership to Administrators, I could not change any permissions for the registry key to full control for:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{F72671A9-012C-4725-9D2F-2A4D32D65169}

Is there a service that I need to stop in order to be able to change the permissions? Or is administrator not a high enough user level?

I also got the Event ID 10016 error for a different DCOM service RuntimeBroker.

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 
{D63B10C5-BB46-4990-A94F-E40B9D520160}
 and APPID 
{9CA88EE3-ACB7-47C8-AFC4-AB702511C276}
 to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

I also have the same problem when trying to change the permission on the key: 

HKEY_CLASSES_ROOT\CLSID\{D63B10C5-BB46-4990-A94F-E40B9D520160}
