Although it is a common problem, there are still many people. It's not very clear, so the following editor will tell you how to open the win7 camera !
How to open the camera in win7 system:
1. In the key "Computer", select "Manage".
2. After entering, click "Device Management"
3. After entering the device management, find "image device", find "usb2.0...." (different devices display different), then right-click and select "Properties"
