Way-4: Update or Uninstall Driver

Sometimes, especially when an unknown bug is affecting a driver update, the updated version can create problems instead. This is also applicable to Camera which is showing error code 0xA00F429F.

Hence you need to check whether the problem started after installing an update for the app and delete it if this happened. There is also an option Roll back you can use in this case through Device Manager. You may even delete the driver and replace it with Microsoft basic driver to break the continuity of error code.

You may lose certain functionality of the official driver as a result of this step. Still, if you only want to chat, snap photographs, or record video using the Windows Camera app, this may be a good option for you. So, move forward with the steps –

2. Lastly, reboot the device and the issue should be solved now.

Way-5: Allow camera to communicate through  Windows Firewall or Third-Party Antivirus

We have seen several times, how firewall or third-party antivirus applications can misjudge Windows applications as a security threat and hinder their performances. Camera Error code 0xA00F429F might be the result of this misbehave.

Way-6: Reset the Permissions

After receiving a major release on Windows 11 you may need to authorize your programs to utilize the camera again.

Follow the steps below to provide your apps access to the camera:

1. Go to Start => Settings.
2. Select – Privacy & Security.
3. Select – Camera.

Way-7: Close all the Background Apps

Using Physical Buttons on Different Laptop Brands

If you are experiencing a camera error on your laptop, the first thing to check is whether the camera is turned on or off using the physical button. Here are the methods to turn on the camera for different PC manufacturers:

• MSI Laptops: Press the “Fn” key and the “F6” key simultaneously to turn on the camera.
• ASUS Laptops: You can turn on the camera by pressing either the “F10” key or “Fn + F10” together.
• HP Laptops: Look for the Kill Switch button on the left or right side of the laptop. Slide it to the ON position to activate the camera.
• Lenovo Laptops: To turn on the camera, press the “F8” key or use the combination “Fn + F8“.

Make sure to try these steps to ensure the camera is enabled before troubleshooting further camera issues.

Update, Uninstall, and Reinstall Camera Drivers

You need to ensure that the Camera device is up to date for proper functioning. You can follow the instructions discussed here: How to Update Drivers for Windows 11.

The blog post has instructions on how to update, delete, and reinstall drivers on Windows PCs.

Alternatively, you can head over to the manufacturer’s website and download the latest Camera driver for your Windows PC or use OutByte Driver Updater.

Check Windows 11 privacy settings

Another possible cause of the 0xA00F429F error is incorrect privacy settings. To check your privacy settings, follow these steps:

Open the Settings app in Windows 11. For that, click on the Start button and select Settings from the start menu.

Switch to Privacy & Security on the left.

Картинка с сайта: geekermag.com

On the right side, scroll down until you reach to App permissions section and click on the Camera.

Make sure that the Camera Access setting is turned ON.

Run the Camera troubleshooter

Windows 11 includes a built-in troubleshooter that can help you fix problems with the Camera app. To run the troubleshooter, follow the instructions discussed below:

Click on the Search icon and type Troubleshoot other problems. When the same setting appears in the search results, click to open it.

Scroll down to Camera Troubleshooter and then click on the Run button.

Картинка с сайта: geekermag.com

Follow the on-screen instructions and let the troubleshooter find and resolve the issue.

Reset the Camera app

If the above steps do not fix the problem, you can try resetting the Camera app. To reset the Camera app, follow these steps:

Click on the Search icon and type Camera, when the same app appears in search results, click to open it.

Картинка с сайта: geekermag.com

Click on the App settings option available on the menu.

Картинка с сайта: geekermag.com

In the App settings page, scroll down to the Reset section, then click on the Reset button.

Use Registry hack

Click on the Search icon and type regedit, when the Registry editor appears in the search results, click to open it.

In the Registry Editor, go to the following key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform

Once you are at the correct key, right-click on an empty area and select New > DWORD (32-bit) Value.

Картинка с сайта: geekermag.com

A new DWORD value will be created, and you should name it “EnableFrameServerMode.” Double-click on it and set its Value data to 0.

Ensure that the “Base” is set to “Hexadecimal.”

Click on “OK” to save the changes.

Close the Registry Editor. To apply the changes.

When the “EnableFrameServerMode” DWORD value is set to “0” (with the Base value set to Hexadecimal), it effectively disables the Frame ServerMode for cameras. The Frame ServerMode is a feature in Windows that allows multiple applications to access a camera simultaneously.

By disabling this feature, only one application at a time can access the camera, which might be necessary to resolve certain camera-related issues or conflicts.

After that, open the camera app and check if this fixes the issue or not.

Disable the Camera Shields feature in the Antivirus Program

Some third-party antivirus software packages have features like “camera shields” that can block access to the camera. If you are using one of these packages, then try to disable this feature to fix the issue:.

The steps to disable the camera shields or similar features will vary depending on the antivirus software package you are using. However, in general, you will need to open the antivirus software settings and find the section that deals with camera protection. Once you have found this section, you should be able to disable the camera shields.

Reinstall the Camera app

If resetting the Camera app does not fix the problem, you can try reinstalling the Camera app. To reinstall the Camera app, follow these steps:

Uninstall the Camera app

Press the Windows key on your keyboard to open the Start menu.

Type “PowerShell” in the search bar. Right-click on “Windows PowerShell” from the search results and select “Run as administrator” from the context menu.

If the UAC dialog box appears, click “Yes” to continue with administrative privileges.

Картинка с сайта: geekermag.com

In the PowerShell window, paste the following command and press Enter:

Get-AppxPackage *camera* | Remove-AppxPackage

This command will uninstall the Camera app from your system.

Reinstall the Camera app from the Microsoft Store

Open the Microsoft Store app on your Windows 11 PC.

Click on the Search icon and type Camera, when the same app from Microsoft appears in search results, click to open it and then click on the Install button.

Картинка с сайта: geekermag.com

Once the installation is complete, you should have the Camera app back on your computer.

Please note that performing these steps will remove and reinstall the Camera app. If you have any important data or settings associated with the Camera app, make sure to back them up before proceeding.

Turn ON the Camera from the BIOS

Checking camera settings in BIOS may not be available on all PCs. Typically, this feature is found in business-class PCs running Windows 10, allowing users to enable or disable the camera or webcam system-wide.

If your device supports this functionality, you can follow these steps:

You can enter your device into bios and check if it’s available or not.

Navigate to the appropriate section, which might be labeled as “System Configuration” or “Miscellaneous Devices.” Check if there is an option to “Enable Camera.”

Картинка с сайта: geekermag.com

Enable it by checking the box. Save the changes by clicking “Apply” and then exit the BIOS.

Restart your computer to apply the changes.

Please note that this method applies to Dell PCs in the example provided. If you are using a different brand, refer to their official website or documentation for specific instructions on accessing camera settings in the BIOS.

Keep in mind that not all PCs support camera management through BIOS, so this option may not be available on your device.

Scan your computer for malware

Finally, if you have tried all of the above steps and the problem persists, you can scan your computer for malware. Malware can sometimes cause problems with the Camera app. To scan your computer for malware, you can use a free antivirus program like Malwarebytes.

Conclusion

These are the steps on how to fix the 0xA00F429F error in Windows 11. If you have followed all of the steps and the problem still persists, you can contact Microsoft support for help.

I hope this blog post was helpful. Please let me know if you have any questions.

Windows 10 and 11 come with pre-installed UWP apps that are essential for daily use. Among these is the Camera app, which allows you to record yourself if your device has a webcam. In case you have uninstalled the Camera app, you can easily reinstall it from the Microsoft Store.

With work from home and distance learning becoming popular because of the coronavirus, a lot of people rely on their camera for their online meetings, remote classes, video calls, online conferences, and even live streaming.

Most of the time, the camera works well with various applications, except for when camera errors like 0xA00F429F happen. Several Windows users have recently found that Windows 10/11 can’t start camera, and error code 0xA00F429F occurs. This has happened to users using Zoom, Skype, Facebook Messenger, and other applications that use the camera, which means that the problem is not program-specific.

When users try to use the application with a camera, only a black screen appears with the following error message:

Can’t start your camera
If you’re sure the camera is connected and installed properly, try checking for updated drivers.
If you need it, here’s the error code: 0xA00F429F<WindowShowFailed>(0x887A0004)

This error has affected several Windows users, particularly those who have recently installed updates.

Reasons Behind Windows 10/11 Can’t Start Camera, Error Code 0xA00F429F

At first glance, it seems like the user gets the “Can’t start camera on Windows 10/11” error 0xA00F429F because of driver problems. It is stated in the error message to check for updated drivers. If you recently installed a system update, such as Windows 10/11 1809 or other major builds, it is recommended to check your hardware drivers for those that need to be updated, including your camera. It is possible that the update corrupted the installed driver for the camera or the manufacturer of your camera has also released an updated driver in response to that system update.

There is also a chance that the update has reset the permissions granted to your applications, so you need to request permission again to be able to use the camera.

Sometimes the error is caused by the simple fact that another application is currently using the camera. Take note that you cannot simultaneously run applications that use the same camera. Depending on the application, you’ll either get the message that the camera is already in use or some other error message, like Windows 10/11 can’t start camera, error code 0xA00F429F.

There are numerous other issues that can cause the “Something went wrong camera” error, and in order to resolve it, you may need to update your drivers to ensure the compatibility of your PC and the device.

Finally, it’s possible that your laptop camera isn’t working for another reason, but thankfully, this article is here to help.

How to Fix Can’t Start Camera Error 0xA00F429F

When you get the Windows 10/11 Can’t start camera error code 0xA00F429F, the first thing you need to do is restart your computer and check if the camera is now working. Determine whether the error affects a specific program only or if it affects all the other applications. If it is program-specific, uninstall the app and reinstall a fresh, clean copy to fix the error.

If you’re using a third-party camera connected via USB, check whether your camera is plugged in correctly to your computer. If there is a switch, make sure that it is turned on. You should also close all other applications that you don’t use but are currently running, particularly those that use the camera as well. For the purpose of troubleshooting this error, leave one application that uses the camera running and close everything else.

To resolve this error, try the solutions listed below:

Solution 1: Give your computer access to the camera.

Картинка с сайта: softwaretested.com

1. Press the Win+X keys on your keyboard to open the Settings
2. Select Privacy from the Settings window.
3. Go to Camera and enable Allow apps to access your camera.
4. If the above-mentioned toggle is grayed out, first enable the Allow camera access on this device

Solution 2: Give the Camera app access to firewall or antivirus.

To give your camera app access to Firewall:

1. Open Cortana search -> type firewall -> select the first option from the list.
2. Select Allow an app or service through Windows Defender Firewall from the Firewall settings.
3. Look for the camera app and grant incoming and outgoing access.

To allow camera access via third-party antivirus software (steps differ depending on software):

1. Double-click the antivirus software icon to launch it.
2. Navigate to Firewall settings and ensure that the Camera app has access.

Solution 3: Reset/Reinstall the Windows Camera App.

If the problem is related to the Camera app itself, you can first reset it by following the instructions here:

1. Open Settings from the Start menu or by pressing Windows + I.
2. Click on Apps > Apps & features and look for Camera from the list.
3. Click on it, then click on the Advanced options link.
4. Scroll down and click the Reset button to reset the app.

If that does not work, you can reinstall the app using a PowerShell command. Press Windows + X, then choose Windows PowerShell (Admin) from the menu. Execute the following command in the PowerShell window:

Get-AppxPackage *camera* | Remove-AppxPackage

This should uninstall the camera app. Next, reboot your computer and install the latest Camera app from the Microsoft Store.

Solution 4: Edit the Registry.

This worked for several Windows users but remember that editing the registry may cause irreversible changes to your computer, so proceed with caution. To resolve this error:

1. Press Windows + S, then search for Registry Editor.
2. Navigate to the following key: Computer\HKEY_LOKAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform
3. Right-click on the right pane, then choose New > DWORD (32-bit) Value.
4. Type in EnableFrameServerMode under Value name.
5. Double-click the newly created EnableFrameServerMode entry.
6. Under Value data, type in 0 with the base value as Hexadecimal.
7. Click OK to save your changes.

Restart your computer and check if the camera is now working.

Solution 5: Reset Permissions.

If you upgraded to Windows 10/11 or installed a major system update recently, you might need to allow your applications again to use the camera. In some more recent versions of Windows 10/11, some programs do not have standard access to the camera by default.

To allow your apps to access the camera, follow the steps below:

1. Click Start > Settings.
2. Click on Privacy > Camera.
3. In the list of apps, choose the applications you want to allow access to your camera by toggling the switch to On.
4. If the switch is grayed out, click Allow access to the camera on this device.

Restart your computer and open the affected application again to see if the camera has been fixed.

Solution 6: Update, Rollback, or Uninstall Camera Driver.

If the older camera driver does not work well with the updated version of Windows 10/11, you can check the manufacturer’s website for the latest version of the camera driver and install it on your computer. You may also consider using tools like Outbyte Driver Updater or similar products to scan your computer for outdated device drivers, including your camera, and potentially update them automatically.

On the other hand, if the driver was updated in the background, you can try rolling back to an older version of that driver, the version that does not trigger the error code 0xA00F429F.

Or, you can uninstall the driver and replace it with the basic driver from Microsoft. There is a chance that you might lose some features, but if you only need to use the camera for some basic video calls or record videos, this might be a good solution for you.

Solution 7: Set up a new user account.

If the error persists, create a new user account and see if the camera resolves itself after switching to a new user account.

Solution 8: Press the camera button/switch.

Some webcams include an external switch. We must turn it on to ensure that it is operational.

Most recent HP laptops include a camera key on the keyboard. Please ensure that it is turned ON. Examine your keyboard carefully to see if there are any mistakes.

Solution 9: Quit all apps running in the background.

Картинка с сайта: softwaretested.com

1. To open Task Manager, press CTRL + SHIFT + Esc at the same time.
2. In the task manager window, find the apps that are running the camera in the background, right-click on them, and choose End task from the menu.

Many users reported that deleting the Camera Roll folder solved their problem. To accomplish this:

1. Press Windows+E at the same time to launch the Explorer window.
2. Select Pictures.
3. Right-click on the Camera Roll Folder and press Ctrl+D on your keyboard to delete it.
