Document 1 is about win7, and then, I bought a drive-free USB camera for a little over 30 before!My desktop works!My laptop doesn't work!Since my laptop can't even install a printer driver, I went to the customer service, and the customer service gave me an introduction to the driver installation method!It's no use!!!
Now the school gate is closed!I want an online interview!On a whim, I installed the driver!Of course, my computer was bought around that time in 2015!It's almost six years now!I understand it well!But I love him so much!I hope he can spend more time with me!

Introduce the process!
1. Open the registry!

2. Follow belowThe order of the pictures, find the corresponding directory!




In fact, the reference to win7 is the same, but in the end, this becomes a lowercase letter!
3. Click the last option, the corresponding directory will be displayed on the right!

Find the Upperfilters and Lowerfilters items on the right, and place them inJust delete it!I only have this one Upperfilters here.(PS: The original properties of the computer are not what it looks like in this picture!)
4. Connect the USB port of the camera to it!
Control Panel-Device Manager-Image Devices

I have several devices installed here!The first one is a software, there is no physical camera, I can't uninstall it, because I heard that uninstalling this software requires reinstalling the system!The second is the original camera of the computer, which can no longer be used!Because, I went to the official website to check, the driver of my camera, the official website has stopped updating!Why!!!!
The last one is the external camera I bought!
5. Install the driver!Desktop is not required to install!My DELL notebook must be installed, otherwise it will not work!Follow the steps for the red highlighter below to install!

Additional: In fact, the original device can also be used!I just tried it again!
1. This is the original equipment of the computer!

2. Click it to update the driver, update toUSB driven!According to the content in the previous "4." step, update to the same driver as the USB device, and you will find that this Integrated Webcam can use the USB camera you plugged in!
