dynamic loading

Dynamic loading refers to the process where a program loads and uses DLL files at runtime rather than at compile time. In Windows, some DLLs require registration via regsvr32 to make their COM components available system-wide, while others are accessed dynamically without registration. The distinction depends on whether the DLL exports COM interfaces or standard functions. To determine which type a DLL is, you can inspect its exports or check if it implements DllRegisterServer. For older installations, registering all DLLs may be necessary, but it's safer to only register those that are COM-based to avoid system clutter.
