Which example are you running?

Sound like it uses a set of argument which gr.audio_windows doesn't understand.

audio.sink should map automatically to audio_windows.sink on windows

It takes two arguments, the sampling freq (must be int, not float or double)
and a device name. This is a string which can contain number determing which 
audio card on your system to use.
If you leave this argument or use an empty string it uses the default 
WAVE_MAPPER device.
audio_windows_sink (int sampling_freq,
                     const std::string dev = ""
                     )

audio_windows does not (yet) understand the third bool ok_to_block argument, 
like audio_alsa has
So if you open the audio device like this
from gnuradio import audio
dst=audio.sink(int(sampling_freq))
or
dst=audio.sink(int(sampling_freq),"")
It should work fine.

If this still doesn't work, you can try:
from gnuradio import audio_windows
dst=audio_windows.(int(sampling_freq))
or
dst=audio_windows.sink(int(sampling_freq),"")

Hope this helps.
