User Interface for Third-Party Group Policy Extensions
If your application must provide specialized policy settings, or if you would like to provide a richer user interface for registry-based policy settings, you can create your own extension snap-in for the Group Policy Object Editor. Your extension snap-ins can communicate with the Group Policy Object Editor using the IGPEInformation interface.
You can write your own Microsoft Management Console (MMC) snap-in to replace the Group Policy Object Editor. For more information, see the IGroupPolicyObject interface and the CreateGPOLink function. For more information about MMC, see the Microsoft Management Console.
