Well, you did say *guess* :-)

NT has:
>>> os.environ['OS']
'Windows_NT'

And a number of other variables that don't exist on 95/98 by default.  Im
not sure if _all_ NT machines have that variable by default , but I sure
didnt add it to my machine (and it exists on all NT W/S and Servers I have
seen)
