Quick and dirty...:

import os
x = os.popen('C:\\')
x.readline(); x.readline()
vsn = x.readline().strip()[-9:]
x.close()


Perhaps too dirty.  If you want to do it via a Win32 API call, you
need to determine what call is it (e.g. via MSDN) and then use
win32all or ctypes to go and call it.  But parsing dir's output
is quite a bit quicker to program;-).
