Fix “Webcam Is Being Used by Another Application” on Windows 10

by

Many Windows 10 users encounter an annoying error message when trying to use their webcam: “Webcam is being used by another application.” This issue can be particularly frustrating, especially if the user is in the middle of a video conference or trying to record content. Fortunately, resolving this error is usually straightforward with the right steps and knowledge.

What Causes This Webcam Error?

The error message typically means that another application has control of the webcam, preventing your preferred program—such as Zoom, Skype, or Microsoft Teams—from accessing it. This could be caused by a background process, misconfigured privacy settings, or drivers that aren’t working properly.

Common Fixes to Resolve the Error

Here are several solutions to address the “Webcam Is Being Used by Another Application” error in Windows 10:

1. Restart the Computer

Simple but effective. Rebooting the system can close any background processes that may be using the webcam without your knowledge. This is often the quickest way to fix the issue if it’s only a temporary glitch.

2. Check for Running Applications That Use the Webcam

If restarting didn’t work, the next step is to ensure that no other applications are using the camera in the background. This can include programs like:

  • Skype
  • Zoom
  • Microsoft Teams
  • OBS Studio
  • Camera app

Close all of these apps and then try reopening the one where the webcam is needed.

3. Use Task Manager to Kill Background Processes

In some cases, software may continue to run in the background even after being closed. Follow these steps:

  1. Right-click the taskbar and select Task Manager.
  2. Click the Processes tab.
  3. Look for any applications that may use the webcam.
  4. Right-click on the process and choose End Task.

4. Disable Webcam Access for Unnecessary Apps

Windows 10 privacy settings can control which apps have access to the webcam:

  1. Open Settings > Privacy > Camera.
  2. Scroll down to “Choose which Microsoft Store apps can access your camera.”
  3. Turn off access for apps that you are not currently using.

This ensures that only your intended application has permission to use the webcam.

5. Update Webcam Drivers

Outdated or corrupted webcam drivers can prevent the camera from working properly. To update them:

  1. Right-click the Start button and select Device Manager.
  2. Expand the Cameras or Imaging devices section.
  3. Right-click your webcam and choose Update driver.
  4. Select Search automatically for updated driver software.

If no updates are found this way, visit the manufacturer’s website to manually download the latest driver.

6. Disable and Re-Enable the Camera

Resetting the webcam in this way can clear up software conflicts:

  1. Go to Device Manager.
  2. Expand the Cameras section.
  3. Right-click on your webcam and select Disable device.
  4. Wait a few moments, then right-click again and choose Enable device.

7. Scan for Malware

In rare cases, malware can hijack webcam access without the user’s knowledge. Running a full system scan with Windows Defender or third-party antivirus tools like Malwarebytes can ensure no malicious applications are utilizing the camera in the background.

8. Perform a Clean Boot of Windows

Performing a clean boot starts Windows with minimal software and drivers, helping identify potential software conflicts. Here’s how:

  1. Press Windows + R to open the Run dialog.
  2. Type msconfig and press Enter.
  3. Go to the Services tab and check Hide all Microsoft services.
  4. Click Disable all.
  5. Go to the Startup tab and click Open Task Manager.
  6. Disable all startup items, close Task Manager, and then reboot.

If the issue disappears during a clean boot, re-enable items one by one to identify the culprit.

9. Use Windows Camera Troubleshooter

This built-in tool can detect and fix issues related to the webcam:

  1. Go to Settings > Update & Security > Troubleshoot.
  2. Click on Additional troubleshooters.
  3. Select Camera and click Run the troubleshooter.

Follow the on-screen instructions to apply any recommended fixes.

10. Reinstall the Webcam Driver

If all else fails, try uninstalling and reinstalling the webcam driver:

  1. Open Device Manager.
  2. Right-click your webcam and choose Uninstall device.
  3. Restart your computer. Windows will reinstall the driver automatically.

Still Facing Issues?

If none of these steps have resolved the webcam issue, consider rolling back to a previous system restore point or reinstalling the application you’re trying to use. In some rare cases, the problem may be hardware-related, especially if using an external USB webcam that could be malfunctioning. Testing the webcam on a different computer can help narrow this down.
