MPICH2 on Windows XP: No go with MPI_Comm_spawn

I was practicing MPI-2 dynamic process creation on Windows XP, using MPI_Comm_spawn() function call as an alternative to process execution by "mpiexec", but so far haven't been successful. During a search for the previous MPI post, I came across the following Frequently Asked Question (FAQ) on Argonne Website and felt discouraged:

Q: On Windows, I get an error when I attempt to call MPI_Comm_spawn.

A: On Windows, you need to start the program with mpiexec for any of the MPI-2 dynamic process functions to work.

I will give up the attempt for the time being and go on the "mpiexec" way.
