I was looking for a webcam supports Windows 8.1 and finally ... it works !! ... Phew (at the same time it is proposed by Microsoft, so it was better; o)) Also the quality is good, as well as audio video (yes, a microphone is incorporated). Under Skype, no problem. The attachment is quite good, we might as well put it on the desk that hang on the screen. No problem when connecting (USB simply) or at the "reignition" of the PC.
