But that would include DOS-based (i.e. not Win32) versions of Windows like 
3.1.

Often (that is, by default) the environment variable %COMSPEC% includes the 
string "cmd.exe" on Win32. When it does, you can use that as a pointer to 
CMD.

However, this is not always the case (since you can obviously use a different 
command interpreter).

But you *can* check the existence of %windir%\system32\cmd.exe and use it if 
you find it (or is it better to use %SystemRoot%\system32\cmd.exe instead?).
