Avoiding Conflict Over Shared Device (Camera, Error 0xA00F4243)
When you try to use the camera on your computer, you may sometimes encounter the “Close other apps. It looks like another app is using the camera already” error. It’s also accompanied by the 0xA00F4243
This issue is inconvenient, especially if you’re not actively running another app that’s using your webcam and you have an important meeting or stream coming up soon. So, how do you fix this? Check out the steps below and see how to get your webcam working again.
1. Check Your Camera Access History
Windows 11 keeps track of apps that have tried to access your camera recently. In theRecent activity section of theSettings app, you can view which apps have accessed your camera in the last seven days.
Most webcams feature an integrated LED to indicate if the camera is in use. If the light is on, it is likely a background app triggering the error. If the error occurs without the camera light, the issue could be with the camera driver or hardware.
To view your camera’s recent activity:
- PressWin + I to open theSettings app.
- In the left pane, open thePrivacy & security tab.
- Next, scroll down to theApp permissions section.
- Click on theCamera option to view more options.
- Click onRecent activity to view a full list of apps that have accessed your camera in the past seven days. It shows the app’s name with the date and time.
If there is no suspicious app in the list, closeSettings . If yes, check if the suspected app runs in the background and quit it to fix the issue.
To close a background app, click theUp-arrow icon in the system tray. Next, right-click on the app name and selectExit ,Quit , orClose .
You can also end the app using the camera from the Task Manager. Check out our guide to learn how to use the Windows Task Manager . But if you need to fix the issue quickly, here’s how to end background apps using it:
- Right-click onStart and selectTask Manager.
- In Task Manager, open theProcess tab.
- Next, locate and select any app that may have access to your camera. Often meeting apps such as Teams are what causes the issue.
- Click onEnd Task to close the app and release the camera access.
If the issue persists,perform a quick restart of your Windows computer to force close any glitchy apps and process to fix the error. If the app continues to hijack your camera, you can restrict the camera permission for the app. Here’s how to do it.
- Open theSettings app and click onPrivacy & security.
- Scroll down and click onCamera .
- Expand theLet apps access your camera option.
- Next, locate the app and toggle the switch to restrict the app from accessing your webcam.
2. Restart the Camera Service (CamSvc)

To fix the issue, you can manually restart the service. While the serviceStartup type for this service, by default, is set toManual , you can set it toAutomatic if the error continues to occur after every system restart.

Also, install any firmware updates from your computer manufacturer to see if that helps resolve the error.
To install Windows updates:
- Click onStart and selectSettings .
- Scroll down and open theWindows Update tab.
- Next, click onCheck for updates . Windows will scan for new updates and list them accordingly.

4. Switch the USB Port Where Your Camera Is Connected
If you’re using an external camera connected to a USB hub, try connecting it directly to a different USB port on your computer. External devices connected to a USB hub can sometimes stop working due to insufficient power and compatibility issues.
Connect your external camera to a different USB port on your computer and check if it helps resolve the error. If yes, connect the camera to a spare USB hub to rule out any issues with your current USB hub.
5. Reinstall the Camera Drivers
You can fix the 0xA00F4243 error by reinstalling the camera drivers from Device Manager. Alternatively, perform a driver rollback to resolve issues that occurred after a recent update.
To uninstall the camera driver using Device Manager:
- PressWin + R to openRun .
- Typedevmgmt.msc and clickOK to open Device Manager.
- In Device Manager, expand theCamera section.
- Next, right-click on your installed camera and selectUninstall device .
- ClickUninstall to confirm the action. Once done, restart your computer to apply the changes.
- After restart, Windows will automatically detect the connected devices and install the necessary drivers for your camera.
To roll back the camera driver:
- In DeviceManager , right-click on your camera device and selectProperties .
- Open theDriver tab in theProperties dialog.
- Next, click onRoll Back Driver and confirm the action. If the option is grayed out, you don’t have any older drivers to restore.
