Issue: How to Fix Webcam Error Code 0xA00F4243(0xC00D3704) on Windows?

I have recently tried to use the webcam on my Windows computer. Unfortunately, I continuously receive “Close Other Apps. It looks like another app is using a camera already.” message and cannot use it. Also, it indicates error code 0xA00F4243(0xC00D3704) in the notification as well. Is there anything I could do to solve this problem?

Solved Answer

Error code 0xA00F4243(0xC00D3704) is an issue which has been appearing on Windows phones, laptops, and other devices. In most of the cases, the appearance of the error indicates that there is an interruption between two programs using the inbuilt camera on the device with Windows OS[1].

Usually, 0xA00F4243(0xC00D3704) error is displayed together with the following message which pops up when trying to use the webcam:

Close Other Apps. It looks like another app is using a camera already. If you need it, here’s the error code: 0xA00F4243(0xC00D3704)

The webcam 0xA00F4243 0xC00D3704 error code message is quite explicit as it indicates the possible culprit of the problem – another application. Therefore, it would be practical to open Task Manager and check what applications are currently running on the system. In case a tool that requires Camera is running, end its task and check if that helps.

Another solution for “it looks like another app is using the camera already” malfunction of the camera would be a clean boot of the system. It would help to isolate the problematic application and, furthermore, repair it. The “another app” may not necessarily refer to Skype, Messenger, or another legitimate application that uses Camera.

It may turn out that the app causing error code 0xA00F4243(0xC00D3704) is a malicious cyber infection, for example, Trojan[2], Worm or adware[3]. To make sure that you are not dealing with such a case, you should run a scan with Reimage or another anti-malware tool.
