How can I add additional templates to a Group Policy Object?

Start the Active Directory Users and Computers MMC snap-in (Start - Programs - Administrative Tools - Active Directory Users and Computers)

Right click on the container whose GPO you wish to change, for example savilltech.com and select Properties

Select the 'Group Policy' tab

Select the GPO and click Edit

The Group Policy MMC snap-in will be started with the GPO at the root

Under User or Computer configuration right click on 'Administrative Templates' and select 'Add/Remove Templates'

Click Add (or to remove select one and click Remove)

Select the ADM to add and click Open

Click Close

The new options will now be available
