5 Ways Fix Windows 10 Camera Not Working

When the Windows 10 camera is not working on your computer, tablet, or smartphone, you can fix it as:

1. Check the Camera Button on your Device 

A physical camera button is available on some laptops and portable devices to switch on and off the webcam. If the camera button is turned off, your device won’t recognize the camera, and you can’t use it. You need to make sure that the button is on before using the camera. 

2. Update your Camera Driver 

The webcam not working problem arises when your camera drivers are outdated. The simple way to fix this problem is to update your camera driver:

Update your Camera Driver
  • Use the Start menu to open the Device Manager. 
  • Navigate to the Imaging Devices and look for your camera. 
  • Right-click on the camera and click on the Update Driver Software. 
  • Or, you can open your manufacturer’s website and automatically update the camera driver by following the installation instructions. 

3. Provide a Permission to the App 

Suppose your webcam was perfectly working with Skype until you switch to WhatsApp. This Windows 10 camera is not working issue may be due to camera access permission to the specific app. So, you should check camera access settings to clear your doubt. 

rovide a Permission to the App
  • Go to Start > Settings > Privacy > Camera. 
  • Under the Allow access to the camera device on this device select Change, turn on Camera access for this device, and Allow apps to access your computer. 
  • To grant access to WhatsApp or other apps, scroll down to Choose which Microsoft Store app can access your camera and turn on the video conferencing app. 

4. Analyze your Incompatible Camera Driver 

Incompatible Camera Driver

If you are using an older camera that is not designed for Windows 10, your webcam will not work for you. To check the incompatible camera driver, follow these steps:

  • Go to the Device Manager, navigate for your Camera or Imaging Devices tab. 
  • Right-click on your camera and select Properties. 
  • Click on the Driver tab, select the Driver Details button, and look for a file name. If your camera was designed before Windows 7, you have to replace your camera. 

5. Uninstall your Camera Driver 

When nothing fixes Windows 10 camera not working for you, as a last resort, you can uninstall your camera driver and scan for hardware changes. Before that do take a backup of your camera driver settings.  

  • Open the Device Manager, right-click on your camera, and select Properties. 
  • Click on the Driver tab and then Uninstall Device. Select the check box for Delete the driver software for this device, then select OK. 
  • Next, click on the Action menu from the Device Manager and select Scan for hardware changes. 
  • You have to wait for the scan to complete and reinstall updated drivers on your PC. 

5 Ways to Fix Mac Camera Not Working 

On your powerful Mac devices, webcam not working is possible and can be fixed easily with:

1. Close Other Camera Apps 

Close Camera Apps

If you are using multiple camera apps on your Mac, switching from one app to another can cause the Mac camera not working. For instance, if you open the Zoom app without closing the FaceTime camera, your Zoom camera will not work. Therefore, close all other camera apps before using your camera.

  • Press hold ⌘ Cmd + on the keyboard. 
  • Type Activity and select the Activity Monitor. 
  • Double click on all other apps using the camera and select Quit on the window that pops up. 

2. Reset your System Management Controller

If you are facing a webcam not working issue along with some other issues on your Mac, resetting SMC is a good idea. The resetting method depends on your Mac type. The SMC on MacBook containing Apple T2 Security Chip is:

  • Power off your Mac. 
  • Hold the following keys for seven seconds — ⌘ Cmd + ⌥ Option + ⇧ Shift. 
  • While holding these keys, hold the power button for another seven seconds. If your Mac has turned on, it will turn off now. 
  • After a few minutes, turn on your Mac. 

To reset SMC on all the Macs released in 2010 or later:

  • Power off your Mac. 
  • Hold together ⌘ Cmd + ⌥ Option + ⇧ Shift. 
  • Also, hold the power button for ten seconds. 
  • Power on your Mac. 

3. Stop the VDC Assistant and Apple Camera Assistant Processes

The VDCAssistant and AppleCameraAssistant are two processes that perform webcam duties in the background on your Mac. If these processes stop working correctly, it can cause the Mac camera not working issue. 

Mostly, when a process crashes, the system automatically restarts. Sometimes, the automatic restart won’t work, and you have to manually kill processes with a terminal command, either searching for it in Spotlight or going to Applications > Utilities. Type the following command, and then press Enter:

sudo killall VDCAssistant;sudo killall AppleCameraAssistant

You need to enter your admin password and then try to use the webcam again. If you aren’t comfortable with terminal commands, you can also restart your Mac. 

4. Check Screen Time Permissions

Screen Time Permissions

Screen Time is a core macOS feature that monitors your Mac’s usage. It is a macOS parental control handler that includes restricting access to the webcam. If you have restricted webcam access, your Mac camera will not work.

To confirm the Screen Time restriction problem, follow these steps:

  • Go to System Preferences > Screen Time > Content and Privacy and click on Camera. 
  • If the Camera is disabled under the Apps tab, you can authenticate or change the settings. 

5. Evaluate the Camera Indicator Light

When your Mac camera is not working after all your attempts, you should closely observe the camera indicator light. If the camera flashes green on your Mac notebook, you should immediately contact Apple support to get help.
