As Bob has already pointed out, you have a few issues with your code that
should be fixed (such as, remove the call to "GetExitCodeProcess()"...it's
is being used at an improper time, and you aren't using the return value for
anything).

However, I believe the solution to your problem is to create the process
"detached":

>     NULL,           // primary thread security attributes

>     DETACHED_PROCESS,              // creation flags

>     NULL,           // use parent's current directory
>     &siStartInfo,   // STARTUPINFO pointer
>     &piProcInfo);   // receives PROCESS_INFORMATION

Also, you should close the process' thread handle:

CloseHandle( piProcInfo.hThread );
