Unfortunately, Windows 7 is installed only a 08/15 driver for Webcams. The features such as HD, etc. that characterize the Webcam so the c930e unavailable. Thus the good hardware is available, unfortunately, only a tiny part. Another minus point: in the 930 version is not software as the 920 there. Although it is possible to install the software 920, but the 920 driver does not want the 930s Webcam ... The only good thing the 930 Cam is the cover flap.
Conclusion: Unfortunately, the C930 is completely unusable. The purchase-relevant, advertised features are not available due to driver problems -> unit returns.
