cmd.exe will not spawn a shell

[null at klin.org (null)]

IIRC, calling directly cmd.exe with win32_exec payload in some Metasploit
Framework 2 modules (i.e. ie_xp_pfv_metafile) didn't work. When setting CMD
string to "start cmd /k" command prompt window popped-up.

I suppose it has something to do with CreateProcess() and hidden window(s). Is
only cmd.exe affected or any Win32 executable in general (i.e. calc.exe)?

Cheers,
