How to completely delete a virtual camera (VCAM)?

I just finished dealing with this problem. I was bored to death all night, and finally got the hang of it! !

Start-enter regedit-running-open the registry-find the VCamService folder and delete the second file in it, so that the virtual camera QQ video will automatically jump out after watching it.

Next, the correct installation method of the universal camera driver is: install the universal driver directly without plugging in the camera first, so that the inf file in the universal driver file will be decompressed into the folder. Then plug in the camera, the system will prompt to find new hardware, and then the system will guide the user to install hardware. Next, the system will let the user select the appropriate hardware, press "Browse" to find the installation folder of the universal camera driver, select the program suitable for the camera in the folder and continue the installation, and then use it after completion. It should be noted that when you are prompted to install, the interface into which the camera is inserted is fixed, and you cannot plug the camera into other usb interfaces. If you plug in the wrong interface, the system will prompt that the hardware cannot be found. This can only clear the camera program and reinstall the universal camera driver according to the above steps.

The phenomenon that the virtual camera automatically jumps out during QQ video is solved, and the universal driver is installed correctly. If QQ video is to be successful, you should also get the video settings in the upper right corner of the QQ dialog box. For example, choose PC-usB as the video device. It's quite verbose, but the problems that will arise are basically solved!
