Class Not Registered Windows 11

If you encounter the Class Not Registered Windows 11 error, it means that a particular component or class required by a program isn’t correctly registered. This issue can occur when an application attempts to use a missing or unregistered DLL (Dynamic Link Library) or COM (Component Object Model) object.

It’s caused by corrupted DLL or COM files on your PC, Windows Registry errors, or other system-related issues. I’ll show you how to resolve this error below!

Preliminary Checks

  • Restart your PC to resolve temporary glitches or conflicts that might be causing the issue.
  • If an app shows the error, try reinstalling it.
  • Make sure your Windows 11 system is up to date.
  • Run the built-in compatibility troubleshooter if the error occurs on an older app that’s not working correctly on Windows 11.

1. Reset Your Default Apps

This process restores apps to their default settings and removes bugs.

1. Right-click on the Start menu and choose Settings.

2. Select Apps > Default apps.

This command will reinstall all Microsoft Store Apps for all users. After successfully executing it, you can close Windows PowerShell and reboot your PC.

5. Use SFC and DISM tools

Windows 11 includes a built-in feature known as System File Checker (SFC) designed to scan your computer, verify the integrity of each system file, and fix any missing or corrupt files.

1. In the Run dialog box, type “cmd” and press Shift+Ctrl+Enter keys to run Command Prompt as administrator.

2. Type “sfc /scannow” and press Enter.

3. Wait until the scanning and repair process is completed. After repairing corrupt or missing files, restart your computer.

The DISM (Deployment Image Servicing and Management) tool can prepare, modify, and repair system images, including Windows Recovery Environment or Setup. Additionally, you can use it to fix system issues with the local recovery image.

1. Run the cmd command from the Run dialog box as administrator.

2. Type the following command in the Command Prompt: “DISM /Online /Cleanup-Image /RestoreHealth” and press Enter.

3. Wait until you see the message “The operation completed successfully.” After that, use the SFC tool again.

6. Use System Restore

You can revert your system to a previous Restore Point when it was in perfect working condition, before the “Class Not Registered” Windows error.

1. Select the search bar and type “restore.”

2. Click “Create a restore point” in the search result.
