It's a rather old utility that loads a DLL (with LoadLibrary), finds an exported function (GetProcAddress), makes its best guess about the expected parameter types from the looks of its command line, and invokes said function. In this case, since there's one parameter and it's not a number, rundll would assume - a single string (LPCWSTR).
