To fix a webcam that is not working in Windows 11 or Windows 10, first turn on Camera access and Let desktop apps access your camera in privacy settings, then reinstall the driver in Device Manager or reset the Camera app.
This guide covers each fix in order, the Windows 10 paths, app and browser permissions, a system file scan, and what the common Camera app error codes mean.

Check Windows privacy permissions (most common fix)
A camera switched off in privacy settings looks exactly like a broken webcam. Desktop apps such as Microsoft Edge, Zoom and Microsoft Teams need the desktop apps toggle on.
- Select Start > Settings > Privacy & security > Camera.
- Turn on Camera access. If the switch is greyed out, an administrator has to turn it on.
- Turn on Let apps access your camera, then switch on the Microsoft Store apps that should use it.
- Turn on Let desktop apps access your camera.
- Close and reopen the app that could not see the camera.
On Windows 10, the page is Start > Settings > Privacy > Camera. Select Change under Allow access to the camera on this device and turn on Camera access for this device, then turn on Allow apps to access your camera and Allow desktop apps to access your camera.
Prerequisites for fixing a webcam in Windows 10/11
| What you need | Why |
|---|---|
| An administrator account | Enabling a disabled camera, changing drivers and running DISM or SFC need admin rights |
| The camera's make and model | Driver downloads and legacy-driver checks depend on it |
| Windows 11 version 24H2 or later for basic camera mode | The Advanced camera options that hold it arrive in 24H2 |
| A second USB port or PC for external webcams | Separates a dead camera or cable from a Windows problem |
Windows 10 support ended on October 14, 2025, so camera driver and app fixes now target Windows 11 first.
Step-by-step: Fix the webcam in Windows 10/11
Work down the list in this order. Each fix takes a minute or two, and the cheap checks come first.
| What you see | Start with | Section |
|---|---|---|
| Black preview or no camera in any app | Physical switch, shutter or cable | 1 |
| Camera works in one app but not another | App-specific permissions | 6 |
| Error says the camera is in use | Close apps holding the webcam | 2 |
| Camera missing from Device Manager or after an update | Driver roll back or reinstall | 4 |
| Camera app itself crashes or freezes | Repair or reset the Camera app | 5 |
| Several devices misbehave at once | Troubleshooter, DISM and SFC | 7 |
1) Confirm the camera isn't blocked physically (fast check)
- Look for a slider shutter over the lens at the top of the screen and open it.
- Check the side of the laptop for a sliding camera switch.
- Look for a camera key or an Fn-key combination on the keyboard that turns the camera off and on.
- For an external webcam, push the USB plug in firmly and try a different USB port.
- Test the external webcam on another PC to rule out a hardware fault.

2) Close apps that might be "holding" the webcam
A webcam already in use by one app can refuse another. Errors 0xA00F4243, 0xA00F4289 and 0x80070005 usually mean another app already has it.
- Close video apps such as Teams, Zoom, Skype and browser tabs with video calls.
- Press Ctrl + Shift + Esc to open Task Manager.
- Right-click any remaining app that uses the camera and select End task.
- Open the app you need and test the camera again.
On Windows 11 24H2 or later, turning on basic camera mode also turns on multi-app camera mode, which lets more than one app share the camera.
3) Test the webcam using the built-in Camera app
- Select Start and open Camera.
- Check whether a live preview appears.
- If the preview works, the webcam and driver are fine, so fix the other app's settings (section 6).
- If the preview fails, note any error code and match it in the error code section below.
If the camera itself is switched off in Windows, you can turn on the camera in Windows 11 from Bluetooth & devices > Cameras.
4) Fix or reinstall the webcam driver in Device Manager
Driver problems are the usual cause after a Windows update. Roll back first, then reinstall.
- Select Start, type device manager and open it.
- Expand Cameras, Imaging devices or Sound, video and game controllers and find the webcam. If it is missing, select Action > Scan for hardware changes.
- If the camera shows Enable device on right-click, select it.
- To roll back, right-click the camera, select Properties > Driver > Roll Back Driver > Yes, then restart.
- If roll back is unavailable, right-click the camera, select Properties > Driver > Uninstall Device, tick Attempt to remove the driver for this device and select OK.
- Select Action > Scan for hardware changes, restart the PC and test again.
- Install camera drivers offered under Settings > Windows Update > Advanced options > Optional updates, or from the manufacturer's site.
For an external USB webcam, you can switch to the Windows UVC driver: right-click it, select Update driver > Browse my computer for drivers > Let me pick from a list of available drivers on my computer, choose USB Video Device and select Next. The in-box driver can disable features such as Windows Hello face recognition.
On Windows 10 the uninstall box reads Delete the driver software for this device. If Driver Details lists a file named stream.sys, the camera predates Windows 7 and needs replacing.
5) Reset or repair the Camera app (Windows 10/11)
Try Repair first and use Reset only when Repair is missing or does not help. Some apps show only one of the two buttons.
- On Windows 11, select Start > Settings > Apps > Installed apps.
- Find Camera, select the More (three dots) icon and select Advanced options.
- Select Repair and test the Camera app.
- If it still fails, return to the same page and select Reset.
- On Windows 10, select Start > Settings > Apps > Apps & features, select Camera, then Advanced options, and use Repair or Reset the same way.
6) Check app-specific camera permissions (Teams/Zoom/Browsers)
When the Camera app works but a meeting app does not, the block sits inside that app or browser.
- In Settings > Privacy & security > Camera, turn on the app by name, such as Microsoft Teams (work or school); if it is already on, turn it off and on.
- In Teams, open Settings > Devices and select Make a test call to check the camera.
- In Zoom and other desktop apps, pick the correct webcam in the app's video settings and confirm Let desktop apps access your camera is on.
- In Microsoft Edge, open Settings > Privacy, search, and services > Site permissions > All permissions > Camera and turn on Ask before accessing (recommended).
- In Google Chrome, open Settings > Privacy and security > Site settings > Permissions > Camera, select your webcam in the dropdown and choose Sites can ask to use your camera.
- Reload the meeting page and allow the camera prompt.
7) Run Windows troubleshoot checks (quick system integrity pass)
Run the camera troubleshooter first, then repair Windows system files if several devices or apps misbehave.
- On Windows 11, select Start > Settings > System > Troubleshoot > Other troubleshooters, then select Run next to Camera.
- On Windows 10, select Start > Settings > Update & Security > Troubleshoot, then Camera > Run the troubleshooter.
- Type cmd in Search, right-click Command Prompt and select Run as administrator.
- Run
DISM.exe /Online /Cleanup-image /Restorehealthand wait for it to finish. - Run
sfc /scannowand leave the window open until verification reaches 100%. - Restart with Start > Power > Restart; sleep is not a restart.
"Windows Resource Protection did not find any integrity violations" means system files are fine, so the cause is the camera, its driver or an app.

8) If it still doesn't work: isolate the cause
| Test result | Likely cause | Next move |
|---|---|---|
| Fails on this PC and on another PC | Webcam or cable hardware | Replace the webcam or contact the maker |
| Works on another PC, not on this one | Driver, policy or Windows setting | Driver reinstall, UVC driver, basic camera mode |
| Camera access greyed out | Group policy or work management | Ask your IT admin; error 0xA00F4292 points here too |
| Works in Camera app only | App or browser permission | Section 6 |
| Stopped after a Windows update | New driver | Roll back the driver in section 4 |
To try basic camera mode on Windows 11 24H2 or later, open Settings > Bluetooth & devices > Cameras, select the camera, select Edit under Advanced camera options and turn on basic camera. It turns off hardware acceleration and manufacturer plug-ins.
