Windows supports a untouched integer mode just fine. In fact, Integer is the default mode on Windows with many audio devices (but because its the default mode, its usually not called that at all)
Depending on your audio device, you would either use ASIO (which is preferred, but only works if your audio device has a ASIO driver), or the WASAPI Exclusive Mode.
Sound Quality should be the same, if you're driving the same DAC.
