We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for azureuser:
Loaded plugins: langpacks, product-id, rhui-lb, search-disabled-repos,
              : subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
No packages marked for update

Actually, below will be always showing up when running yum related command:

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Expected results:
-the output should be indicating this is an registered RHEL.

Additional info:
The "not registered" message could be ignored given the "yum update" actually worked as design. 
but the message provided the bad user experience.
