To create a COM DLL (Dynamic Link Library) from an existing DLL, you need to register the DLL with the Windows registry using the Regsvr32.exe command-line utility. This registration process adds an entry in the system's registry, including the CLSID, ProgID, and IID for the exposed interfaces. Once registered, other applications can use the COM DLL as they would any other COM object.
