Running this on Vista.The actual design of the camera includes a prominent, non-programmable button inexeribly tied to Microsoft Live Messenger. Interestingly, installation of the program is also necessary to unlock access to audio and video settings menu option from the Life Cam software.The video quality is fair with some excessive flaring effect. But the biggest flaw was the inconsistently working mircophone. Even when it was picking up, sensitivity and quality were amazingly poor. Feedback, no matter what the placement of the camera vs. the speakers was very noticeable.I would not recommend this "top of the line" product.
