How to Check If Your Webcam Is Working on Windows 10/11? (Step by Step)

Updated: April 2026

Before You Assume It's Broken

When your webcam refuses to cooperate in Zoom, Skype, or Teams, the issue is rarely a dead camera. Most of the time it comes down to permissions, drivers, or a conflicting app. This step-by-step walkthrough covers every way to diagnose and fix webcam problems on Windows 10 and Windows 11.

Quick Check

  1. Open the built-in Camera app. Press Start → type "Camera" → open the app. If the image appears — the camera is working fine.
  2. Allow camera access. Go to Settings → Privacy → Camera and make sure access is allowed for applications.
  3. Test it through your browser. Visit DoCam.io and click the "Test Camera" button. The website will show video from your camera and technical information — a great way to quickly verify everything is working.

Detailed Guide

1. Checking in Device Manager

Press Win + X → select Device Manager. Open the Cameras or Imaging devices section. If there's a yellow icon next to the device name — there's a driver problem.

2. Updating the Driver

Right-click on the camera → Update driver → Search automatically for drivers. If that doesn't help — download the driver from the laptop or camera manufacturer's website.

3. Checking Permissions

Windows may block camera access. Open Settings → Privacy → Camera and enable the switches for "Allow access to the camera on this device" and "Allow apps to access your camera".

4. Checking Antivirus and Background Apps

Some antiviruses (Avast, Kaspersky, etc.) block the camera. Temporarily disable camera protection in the antivirus settings. Also close all programs using video (Zoom, Discord, OBS) to make sure the camera isn't "occupied" by another process.

5. Checking External Camera (USB)

If your camera is external — try connecting it to a different USB port. Use only rear ports on a desktop computer (they're more stable). You can also test the device on another computer.

Error 0xA00F4244 — No cameras are attached

This error often means a missing driver or hardware-disabled camera (for example, using the Fn + F8 key).

Tips

  • Regularly update Windows and drivers — this eliminates most camera errors.
  • Check the cable and USB port if using an external camera.
  • Use the online test at DoCam.io before starting a video call.

Your Webcam Is Ready for Action

Well done! After running through every step above, your camera should be fully operational. Go ahead and jump into Zoom, Skype, Teams, or any other video app with confidence.
