Office 2010 Administrative Templates - Missing Policies

I have an Office 2010 GPO that needs to enable a policy called "Disable username and password" located at:

Computer Configuration --> Admistrative Templates --> Microsoft Office 2010 (Machine) --> IE Settings

It seems that policy, and any policy that should be there, does not exist.

I have added the admistrative template (.adm) files  for the Office 2010 32-bit version. I have even added the .admx files to \\mydomain\sysvol\mydomain\Policies\PolicyDefinitions as well as added .adml files to "" ""\en-us.

Is there a step that I missed? Any help would be appreciated!

Thanks,
Jasmin
