Hello Youtube! In this video, we will show you how to fix your camera (integrated camera or dedicated camera) if it is not being used by another app or that the windows camera app tells you to close other apps in other to use it. The error it shows is that another app is using the camera already and it shows the error code 0xa00f4243 (0xc00d3704).

This fix is meant as an easy and quick way to get your camera running again but if this doesn't work, the recommendation is to first restart your PC after all the solutions and fixes, and then try reinstalling windows. Meant for all current Windows versions: XP, Vista, Windows 7, 8, 8.1, and of course Windows 10.

My god - have been through three months of struggle, installed/uninstalled, activated/deactivated everything like a million times ... and then all i have to do is press F8 hahahh. But really thanks a lot man, now my camera is finally working again !!

EVERYBODY! i have a potential solution if its your case. I bought the void elite headset from corsair and my camera wasn't working since i was using it. I have this same error but i didn't knew why. Here is how to fix. Make sure there is NO more then 2 microphone connected to your computer. If its not resolved yet if you have the same headset then close it, unplug the bluetooth usb 2.0, then replug it and turn it on. That's what i did and it work. The problem got fixed when i unplugged my old microphone.

As another person in the comments said, the problem for me was that the camera cover accidently slided to cover the camera. I didn't even know there is a camera cover on my laptop, its so tiny! And nobody on the internet ever mentions that this might be a problem. Thank god for that guy who found the solution.

Thank you so much bro!!
You made my day. After a lot of struggles, after losing all the hope I decided to check on one last video and finally I got benefitted from that.
BTW deleting all temp, %temp%, prefetch worked for me.

THANK YOU SO MUCH ! My camera came alive after I followed your instructions to go into Device Manager to disable and enable camera. You are a genius and thanks for sharing this youtube clip.

I just want to say THANK YOU!! I tried so many things to get my camera working again and your recommendation re uninstalling and updating drivers was the ticket. Thank you so much!

Thanks . I was able to get 2 cameras to be used -ONE AT A TIME - but not simultaneously and not displaying in the same or seperate windows. There are some apps that allow 3 cameras - but windows photo app is not one of them. Its one at a time. If you are still seeing that error. Try making sure the plug and play services are all working and that the second webcam is really working. The device manager needs plug and play. So add that to your list. and use a decent cable for the camera some of those that come with the web-cams are cheap.

Changing the camera privacy settings fixed it for me on my laptop. Had to switch the settings to allow apps to use camera. Cheers!
