#includeIn this example, we first initialize the COM library (required for many Windows APIs), create an instance of the GroupPolicyObject class, and then call the GetGUID method to retrieve the unique identifier for the group policy object. We can then use this GUID to identify and manipulate the group policy object as needed. Other C++ libraries that may include a GetGUID function include the Boost C++ Libraries, the Ogre3D game engine, and the Microsoft DirectX SDK. The specific usage and syntax may vary depending on the library, but the basic idea is to retrieve a unique identifier for a group that can be used to track or manipulate it within the larger system.IGroupPolicyObject* pGPO; GUID guid; CoInitialize(nullptr); CoCreateInstance(CLSID_GroupPolicyObject, nullptr, CLSCTX_INPROC_SERVER, IID_IGroupPolicyObject, reinterpret_cast (&pGPO)); pGPO->GetOptions(&dwOptions); pGPO->GetGUID(&guid); pGPO->Release(); CoUninitialize(); // Use the GUID to identify the group policy object
