The recent Windows 10 update is breaking webcams

It won’t support two encoding processes and fixes aren’t coming until September. If you've installed the recently-released Windows 10 Anniversary Update and noticed your USB webcam is acting screwy, you're not alone. It seems the decision to prevent them from using the popular MJPEG and H.264 encoding processes in favor of the NV12 and YUY2 formats is affecting far more devices than Microsoft anticipated, causing millions of cameras to crash. Why restrict them? As Thurrott first pointed out, the Anniversary Update permits possible new situations wherein multiple applications access the webcam and the banned processes would duplicate the encoding stream, slowing it down. Limiting compression formats would seemingly prevent multiple simultaneous processes.
