Window's command processor doesn't recognise single quote marks as 
meaning anything special, so your command is passing 4 separate arguments 
to timeit.py instead of the 1 argument that a unix shell would be passing.

Try using double quotes around everything instead:

timeit.py "if hasattr(int, '__nonzero__'): pass"
