7. Verifique seu aplicativo de segurança da Internet

If you have a cyber-security solution installed on your computer, it could have a special feature dedicated to blocking webcam access, in an effort to stop spies from watching your every move.

Since the application overrides your computer settings, it could be the reason why you keep getting the 0xa00f4244 NoCamerasAreAttached error code.

To fix this problem, just locate the webcam feature in your Internet security program and shut it down to allow webcam access to all your installed applications.

8. Review Camera app permissions

1. Press the Win key, type Camera, and go to App settings
2. At App permissions, enable Camera, Microphone, Videos, and Background apps

1. Right-click the taskbar and select Task Manager
2. Locate all apps with camera access beside Camera
3. Select each app and click Disable
4. Also, disable the Camera app

How to terminate all Camera app processes:

1. Press the Windows button, type Camera, and select App settings
2. Scroll down and click Terminate
3. Right-click the taskbar and go to Task Manager
4. Look for the Camera process. If you can still find it here, select it and click End task

How to reinstall the Camera app using PowerShell:

1. Click the Start button, type Windows PowerShell, and select Run as administrator
2. Type Get-AppxPackage-allusers | Select Name, PackageFullName and press Enter

If you have recently installed third-party software applications, they might not be fully supported by Windows 10, resulting in various functionality issues. In some cases, they can even cause error 0xa00f4244 NoCamerasAreAttached in your Camera app. But you can fix this problem by removing the problematic apps.

5. Reboot your computer and try to use the Camera app

15. Uninstall recent system updates

A system update that rolled out lately might not be fully compliant with Windows 10, resulting in problems with Microsoft Store apps. It can be tricky to tell, but it makes sense if you started receiving the 0xa00f4244 NoCamerasAreAttached error code right after finishing a system update.

To test this, you can uninstall the most recent Windows update. Don’t worry since you can reinstall it later anyway.

1. Press Win key + R, type control panel, and press Enter
2. Click Programs and Features
3. Select View installed updates on the left side
4. Click the Installed On column to sort the updates (newest first)

16. Fix corrupt system files

Your operating system might have damaged or missing files that are directly related to the Windows Camera app. However, you can fix this problem without having to use third-party software solutions, thanks to SFC (System File Checker) and DISM (Deployment Image Servicing and Management).

Get started by running SFC:

1. Press the Windows key + R, type cmd, and press Ctrl + Shift + Enter to open Command Prompt with admin rights
2. Type sfc/scannow and press Enter
3. Wait until SFC finds and fixes any issues
4. Exit CMD and restart your PC
5. Open the Camera app and check for errors

If SFC doesn’t do the trick, then you can turn to DISM to verify the component store of the Windows image.

How to use DISM:

1. Open Command Prompt with elevation rights
2. Run DISM/online/cleanup-image/scanhealth
3. If DISM reports any issues, run DISM/online/cleanup-image/restorehealth
4. Reboot your PC and restart CMD as admin
5. Run the SFC command
6. Restart your computer, open the Camera app, and check for errors

17. Reset BIOS settings to default

Several users reported that they got rid of the 0xa00f4244 NoCamerasAreAttached error message by resetting BIOS settings to default. It’s an easy task that requires just a couple of clicks. Here’s what you need to do:

1. Reboot your PC and quickly press the key shown on the screen to enter BIOS mode
2. Go to the advanced BIOS settings
3. Find the option that resets configuration data and enable it
4. Save the current BIOS configuration and exit to Windows
5. Open the Camera app to check for improvements

18. Check a registry setting

Microsoft Store apps like Camera or Skype need a specific registry in order to function normally. If it doesn’t exist, then you can wake up with error messages like 0xa00f4244 NoCamerasAreAttached.

But you can check this issue by taking a look in Registry Editor and by adding the entry if it’s missing. Don’t worry since there’s no risk of damaging your PC because you will create a registry backup first.

1. Click the Start button, type Registry Editor, and select Run as administrator
2. Click Yes if prompted by UAC (User Account Control)
3. Open the File menu and select Export
4. Write a file name and indicate a folder where you want to save the registry backup. Then, click Save
5. If you’re running 32-bit Windows, visit the following location

   Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform

6. For 64-bit Windows, go to this address instead

   Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform

7. Check if you have an entry called EnableFrameServerMode
8. Otherwise, open the Edit menu, click New, and select DWORD (32-bit) Value
9. Rename the entry to EnableFrameServerMode
10. Double-click EnableFrameServerMode and set its Value Data to 0
11. Set Base to Hexadecimal and click OK
12. Exit Registry Editor and restart your PC
13. Open the Camera app to see if it works now

If you have started experiencing other issues on your computer after making this registry change, you can roll back settings by double-clicking the.reg backup file you previously created. Or, if you didn’t create a backup, simply revisit that registry location and delete the EnableFrameServerMode entry.

19. Create a new user profile

It’s pretty rare, but the Camera app might not be working properly due to data corruption in your user profile. As a result, you get the 0xa00f4244 NoCamerasAreAttached error on your screen. But you can fix this problem by setting up a new local user profile. Here’s how to do it:

4. Set up the username and password of the new account
5. Click Change account type and select Administrator
6. Log out of your current account and log back in with the new one
7. Try to use the Camera app now

20. Use System Restore

Finally, if you can’t pinpoint the software event that caused the 0xa00f4244 NoCamerasAreAttached error code, you can roll back Windows 10 if there are any restore points created before the Camera app started acting up. However, keep in mind that it will affect your programs, so you will lose apps installed after the restore point was made.

2. Press Win key + R, type control panel, and hit Enter
3. Select Recovery
4. Click Open System Restore
5. Select a restore point from the list
6. Click Scan for affected programs if you want to learn more about the changes
