Registering the System Registry Provider

The System Registry provider is registered as part of the WMI installation process on Windows. If you are using another platform and want to use the System Registry provider, you must first register the provider yourself following the steps described below.

The following procedure describes how to register the System Registry provider.

To register the System Registry provider

1. Register the provider as a COM server.

   If necessary, you may need to create registry entries. This process applies to all COM servers and is unrelated to WMI. For more information, see the COM documentation in the Microsoft Windows Software Development Kit (SDK).

2. Create an instance of the __Win32Provider class to describe the implementation of the System Registry provider.

   The __Win32Provider instance describes the name of the provider and its class identifier (CLSID).

   The following example describes how to register __Win32Provider as an instance property, event, or method provider.

   // Instance provider
   instance of __Win32Provider as $InstProv
   {
       Name    = "RegProv" ;
       ClsId   = "{fe9af5c0-d3b6-11ce-a5b6-00aa00680c3f}" ;
   };    
   // Property provider 
   instance of __Win32Provider as $PropProv 
   {
       Name = "RegPropProv"; 
       Clsid = "{72967901-68EC-11d0-B729-00AA0062CBB7}"; 
   }; 
   // Event provider
   instance of __Win32Provider as $RegEvent
   {
       Name = "RegistryEventProvider";
       Clsid = "{fa77a74e-e109-11d0-ad6e-00c04fd8fdff}";
   };
   instance of __Win32Provider as $RegMethod
   {
       Name = "RegistryMethodProvider";
       Clsid = "{44DE513E-60C2-11d3-AF33-00C04F79FEB1}";
   };
   

3. Create one or more instances of classes derived from the __ProviderRegistration class to describe the logical implementation of the System Registry provider.

   Depending on the purpose for which you are registering the System Registry provider, you can create one or more of the following classes.

   __InstanceProviderRegistration

   __PropertyProviderRegistration

   __EventProviderRegistration

   __MethodProviderRegistration

   The following MOF code example describes how you can register the System Registry provider as an instance, property, event, or method provider.

   instance of __InstanceProviderRegistration
   {
       Provider = $InstProv;
       SupportsPut = TRUE;
       SupportsGet = TRUE;
       SupportsDelete = FALSE;
       SupportsEnumeration = TRUE;
   };
   instance of __PropertyProviderRegistration
   {
       Provider = $PropProv;
       SupportsPut = TRUE;
       SupportsGet = TRUE;
   }; 
   instance of __EventProviderRegistration
   {
       Provider = $RegEvent;
       EventQueryList = {
               "select * from RegistryKeyChangeEvent",
               "select * from RegistryValueChangeEvent",
               "select * from RegistryTreeChangeEvent"};
   };
   // Method provider
   instance of __MethodProviderRegistration
   {
       Provider = $RegMethod;
   };
   

4. Compile the MOF file using the MOF compiler or the IMofCompiler interface.

The RegEvent.mof file provided in the WMI section of the Windows SDK contains the __Win32Provider and __EventProviderRegistration instances necessary to register the System Registry provider as an event provider.
