After executing this command, reboot your device and check if the issue persists.
Method 2: Restart the File Explorer App
Restarting the File Explorer app can prove as a useful workaround for fixing minor bugs and glitches. Here’s how you can perform the same using the Windows Task Manager app.

Method 3: Re-register Windows Store Apps
If you encounter the “class not registered” error, certain Windows apps on your system are probably defective or corrupted. In such a situation, a potential solution would involve re-registering all your Windows apps.
Tap on the search bar placed on the Taskbar, type “PowerShell” and select the “Run as administrator” option to launch the app in admin mode.
In the PowerShell app, execute the following command:

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
After executing this command, exit all windows and reboot your Windows PC.
Method 4: Repair Microsoft Visual C++ Programs
To resolve the “class not registered” issue on Windows 10 or Windows 11, one effective approach is to repair or update the Microsoft Visual C++ programs.

Method 5: Run the SFC and DISM Scan
To run an SFC (System File Checker) scan, which helps detect and repair corrupted system files, follow these steps:
- Tap on the search bar and type “Command Prompt”. Select the “Run as administrator” option to launch Terminal with admin privileges.
- In the Command Prompt window, type the following command and press Enter:
sfc /scannow

- Wait for the scan to complete. It may take some time.
Once the scan finishes, the Command Prompt will display the results and notify you if any issues were found and repaired.
After running the SFC scan, run the DISM (Deployment Image Servicing and Management) scan as well. It is a command-line tool in Windows used for servicing and managing Windows installation images, including offline images or running operating systems.
In the Command Prompt window, type the following command and press Enter:

DISM /Online /Cleanup-Image /ScanHealth
Once the scan finishes, the Command Prompt will display the results, indicating if any issues were found with the Windows image. Running the SFC and DISM scans on Windows is an effective solution to fix the “Class not registered” error.

By running this command, you can get a quick overview of the disk drive status for each connected drive on your system.
Method 7: Perform a System Restore
