Interface Key
March 11, 2025 · View on GitHub
Registers new interfaces by associating an interface name with an interface ID (IID). There must be one IID subkey for each new interface.
Registry Key
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Interface\{IID}
| Registry value | Description |
|---|---|
| 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. |
Remarks
The HKEY_LOCAL_MACHINE\SOFTWARE\Classes key corresponds to the HKEY_CLASSES_ROOT key, which was retained for compatibility with earlier versions of COM.
