If you just want to check if winver.exe exists you could just try
os.path.exists("path\\to\\winver.exe") if you know where to expect it
(likely "C:\Windows\system32") or you could use which.py:
>>> import which
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "C:\Python24\which.py", line 248, in which
raise WhichError("Could not find '%s' on the path." % command)
which.WhichError: Could not find 'nothere' on the path.
