How to fix error code: 0xA00F4244<NoCamerasAreAttached>

Check that the webcam is physically enabled, then use Device Manager to determine whether Windows detects it and follow the matching driver branch below.

1. Check the physical camera controls

Error 0xA00F4244 <NoCamerasAreAttached> means Windows cannot detect the camera.^1^

• Open any privacy shutter covering the lens.
• Look for a camera key in the F1–F12 row. Press it once; some computers require Fn + camera key.
• Check the laptop’s sides for a camera switch.
• For an external webcam, reconnect it directly to another USB port rather than through a hub.

Open Start → Camera and test again.

2. Check whether Windows detects the camera

1. Right-click Start and select Device Manager.
2. Look under:
   • Cameras
   • Imaging devices
   • Sound, video and game controllers
3. If the camera is disabled, right-click it and select Enable device. If Disable device is shown instead, it is already enabled.
4. If no camera appears, select Action → Scan for hardware changes, wait for the scan, restart Windows, and test the Camera app.^1^

3. If the camera appears, repair its driver

Install available driver updates first:

1. Open Settings → Windows Update → Check for updates.
2. Then open Advanced options → Optional updates and install any camera driver update.
3. Select Start → Power → Restart.

If that does not fix it, switch to Windows’ generic camera driver:

1. In Device Manager, right-click the camera and select Properties.
2. Open Driver → Update driver.
3. Select Browse my computer for drivers.
4. Select Let me pick from a list of available drivers on my computer.
5. Choose USB Video Device, select Next, and then Close.[^2^](https://support.microsoft.com/windows/hardware/camera/camera-app-shows-error-0xa00f4244-nocamerasareattached#download-and-install-an-updated-driver-from-manufacture's-website "Camera app shows error "0xA00F4244 NoCamerasAreAttached" | Microsoft Support")

The generic driver can omit manufacturer-specific features. If necessary, download the camera driver for the exact computer model from the PC manufacturer’s official support site and install it manually. Avoid third-party driver-download sites.^3^

4. If the problem began after an update

Administrator permission is required to roll back a driver:

1. Open Device Manager and right-click the camera.
2. Select Properties → Driver → Roll Back Driver.
3. Choose a reason, select Yes, and restart.

If rollback is unavailable, uninstall and redetect the driver:

1. Right-click the camera and select Uninstall device.
2. Confirm the uninstall.
3. Restart Windows; Windows will attempt to reinstall the driver automatically.^3^

5. Check camera permission

If Device Manager detects the camera but the Camera app still cannot use it:

1. Open Settings → Privacy & security → Camera.
2. Turn on Camera access.
3. Turn on Let apps access your camera.
4. For browsers, Teams, and other traditional desktop programs, also turn on Let desktop apps access your camera.^1^

If Camera access is greyed out, an administrator must enable it.

If the camera remains absent

If scanning for hardware changes and installing the exact manufacturer driver still produce no camera entry, check the manufacturer’s documentation for a firmware/BIOS camera setting. For an external camera, test it on another computer. If it also fails there—or an integrated camera remains completely undetected—contact the device manufacturer for hardware diagnostics or warranty service.
