Hi, first post here Anyway, I installed Windows build 7057 about 2 weeks ago and since then ( I am upgraded to 7077) the webcam has not been functional. I have a HP tx2500z and have gone to the website to download the latest drivers. The device panel recognizes the USB Camera, but programs like Cyberlink Youcam claim it is unplugged or being used by a different program. The mic's still work. Any ideas?
