Running a standalone cmd.exe

I've got a kernel that didn't include SYSGEN_CMD when it was built but I want
to run it now. I've used the BSP to built cmd.exe but when I copy it onto the
device and run it manually nothing happens. DependencyWalker shows it only
requires coredll.dll but I'm guessing a required library hasn't been built in.

Is there something else I need to include to get this to work, or is it
impossible without rebuilding the kernel to specifically include SYSGEN_CMD?

Thanks.
