Como gerar um clone de um programa?

Function CloneProgram(sExecutableFilePath : string ): string;
var
pi: TProcessInformation;
si: TStartupInfo;
begin
FillMemory( @si, sizeof( si ), 0 );
si.cb := sizeof( si );
CreateProcess(Nil, PChar( sExecutableFilePath ), Nil, Nil, False, NORMAL_PRIORITY_CLASS,Nil, Nil, si, pi );
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
end;
