Why check if maybe "WINOS" is in the environment?
I've personally never seen that variable. Better
check for "WINDIR", or for "COMSPEC"; the first
is, well, the directory under which Windows is
installed, and I've seen that variable in all
the versions I've used: Win95, 98, ME, NT, 2000;
the other one points to the command shell
for that version of windows.

Good luck :-)
