Registers new interfaces by associating an interface name with an interface ID (IID). There must be one IID subkey for each new interface.
|BaseInterface||Identifies the interface from which the current interface is derived.|
|NumMethods||Contains the number of methods in the associated interface, including methods from derived interfaces.|
|ProxyStubClsid||Maps an IID to a CLSID in 16-bit proxy DLLs.|
|ProxyStubClsid32||Maps an IID to a CLSID in 32-bit proxy DLLs.|
The HKEY_LOCAL_MACHINE\SOFTWARE\Classes key corresponds to the HKEY_CLASSES_ROOT key, which was retained for compatibility with earlier versions of COM.
