Group Policy provides a enterprise management of Windows Server 2008, Windows Vista, Windows Server 2003, and Windows XP as well as applications that run on the Windows platform. The enterprise will typically include multiple versions of operating systems and other applications. In order to administrate for these different versions, the Group Policy settings cannot be deprecated when a policy setting no longer applies to the current version operating system or application. Instead of removing Group Policy settings that apply only to earlier operating systems or applications, the Group Policy setting remains in the ADMX files and the supportedOn element is used to specify what operating system or application version is affected by an individual Group Policy setting.

The definition element can be omitted if the ADMX file only requires Windows operating system versions or strings from a custom base file for supportedOn text.


This XML fragment is an example of a single definition of supportedOn text for a specific product version.

      <definition name="SUPPORTED_ProductOnly"
