If you are using the Camera app on your Windows 10 computer but encountered an error code 0xa00f429f with an error message that says, “Can’t start your camera”, read on as this post will guide you in fixing this problem. This kind of error in the Camera app could be due to a recent update gone wrong or it could also be due to a corrupted driver. If you are certain that the camera is connected and is properly installed, you can try to check for updated drivers.

The error code signifies that the drivers have to be updated. However, that isn’t always the case sometimes as the problem could also have something to do with corruption in the driver. The effective ways to troubleshoot this problem would be trying to reinstall or reset the Windows Camera app, or update, rollback or uninstall some device drivers as well as use the Registry Editor. Before you proceed with the instructions provided below, make sure that you have admin privileges and don’t forget to create a System Restore point.

As pointed out earlier, you can also reset the Camera app to fix the error. To do so, follow the steps below.

Option 2 – Try to reinstall the Camera app

If resetting the Camera app didn’t help, you might want to reinstall it by following these steps:

  • Tap the Win + X keys and select the “Windows PowerShell (Admin)” option from the menu to open Windows PowerShell as admin.
  • Next, type this command to uninstall the Camera app: Get-AppxPackage *camera* | Remove-AppxPackage

Option 3 – Try to rollback, update or disable drivers

The next thing you can do to fix the error code 0xa00f429f in the Camera app is to rollback, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to rollback the drivers to their previous versions. Whichever applies to you, refer to the steps below.

  • Open the Devices Manager from the Win X Menu.
  • After opening the Device Manager, look for the device drivers which have a yellow exclamation mark.
  • Then right click on each one of them. If you haven’t updated this driver in a while, select the “Update Driver” option. On the other hand, if you’ve just updated this driver, then select the Uninstall Device option.
  • Next, follow the screen option to update or uninstall it.
  • Finally, restart your computer. It will just reinstall the device drivers automatically if you have chosen to uninstall it.

Note: You can install a dedicated driver in your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 4 – Try to use the Registry Editor

  • Tap the Win + R keys to open the Run dialog box and type “regedit” in the field and then hit Enter to open the Registry Editor.
  • Next, navigate to this registry key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform
  • From there, right click on any empty space on the right side part of the window and select New > DWORD (32-bit) Value.
  • Then name it as “EnableFrameServerMode” and double click on it.
  • Now set its value data to “0” and its base value as Hexadecimal and then click on OK.
  • After that, restart your computer and see if it helped in fixing the problem or not.
