That wouldn't work reliably: Windows 9X doesn't have SystemRoot, and
its system directory is %windir%\system, not %windir%\system32.

Its seems that the most reliable method is to look at the OS
environment variable: if it is set and its value is "Windows_NT", then
use cmd.exe, otherwise use command.com.  I tested this on W2K, XP, and
Windows 98.  So this is my recommendation.
