How to Fix a Webcam That Is Not Working in Windows
Quick answer
Settings → Privacy & security → Camera: Camera access on, and the app allowed. Open the Windows Camera app as a test. If that works, the meeting app is using the wrong device or lacks permission. If Camera is black too, check a sliding privacy shutter and Device Manager. This is not [microphone not working](/guides/microphone-not-working-windows), unmute will not fix a black picture.
Quick diagnosis
If several of these match what you see, you are in the right guide.
- A black rectangle in Teams, Zoom, or the Camera app
- "Camera in use" when you are not on a call
- The camera is missing from the app's device list
- An external USB webcam never appears
Possible causes
- Camera access is off in Windows privacy
- A physical shutter or Fn camera key is closed
- Another app has exclusive use of the device
- The wrong camera selected (IR / Windows Hello versus the color webcam)
- A USB camera that never enumerated
What you need
- Settings → Privacy & security → Camera
- The Camera app or your meeting app
What this problem usually means
Windows Hello infrared cameras are for sign-in. Meeting apps need the color webcam. Picking the IR device looks like a "broken camera." Privacy toggles can allow the Camera app and still block a desktop program until Let desktop apps access your camera is on.
The Camera app is the control test. If it shows video, the sensor and Windows permission path work; fix the meeting app. If it is black there too, focus on shutter, privacy master switch, Device Manager, USB, or the internal camera cable.
Before you start
- Look for a sliding shutter on the bezel. It wins over every software fix.
- Close other video apps. One program can hold the camera.
- USB webcams: try a port on the PC. See USB if the device never appears.
- If you are unsure whether camera, microphone, browser permission, or USB is the real problem, use the PC troubleshooting wizard.
Quick fixes
1. Privacy toggles
- Settings → Privacy & security → Camera.
- Camera access on.
- Let desktop apps access your camera on (for Zoom, Teams desktop, browsers).
- Allow the specific Store app if you use the Camera app or a Store meeting app.
2. Windows Camera app test
- Open Start and search for Camera.
- If more than one camera is available, switch cameras inside the app.
- Look for a live image, an error code, or a black preview.
If you see yourself, Windows and the sensor work. Fix the meeting app's camera dropdown and its own permission prompt. If Camera is black, stay on hardware/driver/shutter.
Step-by-step troubleshooting
In use by another app
Task Manager: end leftover Zoom, Teams, Skype, or browser tabs that had video on. Windows 11 may show a camera icon in Quick Settings when an app is using it, that is a clue, not a virus.
Restart the meeting app after closing the old camera user. Many apps choose devices only when they launch.
Pick the color webcam, not the sign-in camera
Some laptops list an IR camera for Windows Hello and a separate color webcam. In Teams, Zoom, browsers, and Camera, try each camera in the dropdown. The IR camera may look black, grainy, or oddly cropped because it is not meant for normal calls.
Device Manager
Cameras or Imaging devices. Enable the device if disabled. A warning icon: Windows Update or the PC maker's camera driver. Skip driver-booster sites. Disable the IR camera in the meeting app rather than uninstalling it if Hello still needs it.
Browser sites
Chrome and Edge have site permissions for camera, on top of Windows privacy. A site can be blocked while the Camera app works. That is the browser, closer to Edge / Chrome troubleshooting than a new webcam.
Does the Windows Camera app work?
Choose an answer. The next question appears below, no account or download required.
Hardware is fine. Fix the meeting app device list and permissions. Pick the color camera, not IR.
Shutter, privacy master switch, Device Manager, or USB. Do not buy a new webcam until a second app also fails.
Laptop: vendor driver or a disconnected internal cable. USB: USB guide first.
How to know the problem is fixed
Camera app shows video, then the same sensor works in the meeting app after a restart of that app. If the Camera app works but the meeting app does not, the fix is permission or device selection, not hardware.
If the problem continues
Safe Mode is a weak camera test (drivers are limited). If every camera fails in normal mode after privacy is on, a vendor camera app or a Windows update may have left a bad driver, reinstall from the PC maker.
When this may be hardware failure
A laptop camera that is missing in Device Manager after a drop, or that stays black with the shutter open and a USB webcam that *does* work, indicates the internal module or cable. Confirm with a second camera before a bezel teardown.
Common mistakes to avoid
- Uninstalling the IR camera and breaking Windows Hello without fixing the meeting app.
- Covering the lens with tape and troubleshooting a black image.
- Turning off camera privacy for all apps permanently on a shared PC without thinking.
Frequently asked questions
Why does the LED stay on?
An app still has the camera. Close browsers and meeting leftovers. A LED that stays on with no apps listed is worth a scan with Windows Security and a look at Startup apps, still not a reason to call a fake support number.
Can I use a phone as a webcam?
Some official vendor apps exist. Treat unknown "phone webcam" downloads like any other utility: prefer the manufacturer's instructions.
Why does Windows Hello work but video calls are black?
Windows Hello may use an infrared camera while the meeting app needs the color webcam. Choose the other camera in the app's device list before replacing hardware.
