Here’s how to repair and reset the Camera app:

Update the Windows Camera App
If you update Windows regularly, chances are your Camera app is already up to date. However, it wouldn’t hurt to check the Microsoft Store to confirm.
An outdated Camera application could be the cause of the error because it might be lacking the required software components to handle tasks.
So, head to the Microsoft Store, search for the Windows Camera app, and click on Update if it’s out of date. Go to the next solution if your app is up to date.
Fix the Camera’s Driver
Your computer’s hardware devices require drivers to work correctly. The drivers are software programs that interpret the operating system’s commands to each device. If these programs become corrupt or outdated, issues like the error 0x200F4246 (0x80040154) will pop up from nowhere.
Your system’s camera driver could be the cause of the problem. There are different ways to fix driver issues, depending on the situation. If the driver isn’t responding because it’s corrupt or missing specific files, reinstalling it can fix the problem. On the other hand, you’ll have to download and install its updated version if it’s out of date.
Let’s start with reinstalling the driver. Follow these steps:
- Head over to the taskbar and right-click on the Start button.
- Select Device Manager once you see the Power User menu.
- After the Device Manager window opens, expand the Cameras category.
- Right-click on your camera and select the Uninstall Device option in the context menu.
- Click on the Uninstall button in the confirmation pop-up.
- When Windows removes the camera driver, restart your system.
- Your operating system will automatically reinstall the driver once your computer restarts.
- If it doesn’t reinstall the driver, try the next solution to update it.
Update Your Camera’s Driver
Outdated camera drivers can cause all sorts of problems because they don’t work well with new operating system releases. Your current driver could also be configured to work better with previous Windows versions, not Windows 11.
Downloading and installing the latest camera driver for your computer will fix the problem in this case. You can go through the Windows Update client or download the driver from the camera manufacturer’s website or the website of your computer’s manufacturer.
To use Windows Update, open the Settings app (Win + I) and click on Windows Update in the top-right corner. When the Windows Update page shows up, allow the client to download and install pending updates as it’s vital that your computer is up to date. After that, click on Advanced Options and select Optional Updates on the page that follows. Next, expand Driver Updates, look for your camera driver, and check its box. Now click the Download and Install button.
Going through your OEM’s or camera manufacturer’s website is simple. First, open the support page and search for your computer’s or camera’s make and model, depending on which website you’re using. Once you see the right driver, download the correct version for your operating system’s architecture (32- or 64-bit) and install it.
Update Your Drivers Automatically
Using Windows Update and downloading the right driver online can be stressful. With a program like Auslogics Driver Updater, it’s easy to update your drivers without going through the hassle of picking the right architecture and opening different system settings. Once you install the program, it will automatically scan for damaged and outdated drivers on your computer and allow you to update them.
Resolve PC Issues with Driver Updater
Unstable PC performance is often caused by outdated or corrupt drivers. Auslogics Driver Updater diagnoses driver issues and lets you update old drivers all at once or one at a time to get your PC running smoother
With Auslogics Driver Updater’s full version, you can update multiple drivers at once. This way, you don’t have to worry about future driver issues.
Find and Replace Faulty System Files Using the System File Checker
System files are critical to every Windows operation. Some applications malfunction because the system file they depend on is either missing or corrupt. Thankfully, you can use the SFC tool to detect and replace defective OS files. The SFC (System File Checker) tool is a built-in Windows utility that finds and fixes integrity violations of protected operating system files.
Before using the utility, you’ll have to run the DISM (Deployment Image Servicing and Management) tool to provide the replacement files.
Now follow this guide to run the utility:
- Head over to the taskbar, right-click the Start button, and select Run in the Power User menu. You could also tap Win + R to launch Run.
- After Run shows up, type CMD, then go to your keyboard and press Ctrl + Shift + Enter. The combination launches the Command Prompt as an administrator.
- Select Yes in the confirmation pop-up.
- Type this command once the Command Prompt window appears and click on Enter:
DISM.exe /Online /Cleanup-image /Restorehealth
Notes: i. Make sure you add the space before each forward slash (/).
- The process could take 30 minutes or more to complete.
- Wait for the “The operation completed successfully” message before going to the next step.
- Now type this command and hit the Enter key:
Note: Remember to add the space before the forward slash (/).
- Exit the Command Prompt once you see the “Verification 100% complete” message.
- Restart your PC and check if the Camera app now works fine.
Change Settings in Your Antivirus Program
Some system security programs prevent access to your camera by default. This is an attempt to prevent third-party programs and cybercriminals from using your camera maliciously. Go to your antivirus program’s settings page and turn off any feature that blocks access to your camera.
Reinstall the Camera App Through Windows PowerShell
Reinstalling the Camera app will fix the error if it’s caused by broken or missing installation files. Unfortunately, you cannot uninstall most built-in applications through the Settings app. You’ll find the Uninstall button greyed out. However, you can go through the Windows PowerShell command terminal to reinstall the Camera app.
- Go to your keyboard and tap Win + X or right-click the Start button.
- Select Windows Terminal (Admin) or Windows PowerShell (Admin) after the Power User menu appears.
- Click Yes.
- Next, type this command after the Administrator: Windows PowerShell interface appears:
Get-AppxPackage *Microsoft.WindowsCamera* | Remove-AppxPackage
Note: The command will uninstall the Camera application.
- Now open the Start menu and launch the Microsoft Store. If you use Windows 11, it should be couched in the taskbar.
- After the store opens, search for Windows Camera and install the app.
That’s how to fix Windows 10’s “Can’t start your camera” error 0xa00f4246. You now also know how to eliminate it in Windows 10.
