Step 1: Restart Your Computer
One of the simplest and most effective steps to fix the Explorer.exe Class Not Registered Error is to restart your computer. Restarting your computer can help refresh system processes and clear any temporary issues causing the error.
To restart your computer, click the Start menu and select “Restart” from the power options. Alternatively, press the Windows key + X, like “Shut down or sign out,” then choose “Restart.”
It is important to note that a proper restart involves shutting down your computer completely and then turning it back on. Simply clicking the restart button in the Start menu may not have the same effect.
When restarting your computer, it is recommended to wait for a few minutes before turning it back on. This allows any background processes to be completed and ensures a clean restart. Additionally, it is advisable to disconnect any external devices, such as USB drives or printers, before restarting.
Step 2: Run the System File Checker
The System File Checker (SFC) is a built-in Windows tool that scans for and repairs corrupted system files. Running the SFC can help fix the Explorer.exe Class Not Registered Error if corrupted system files cause it.
To run the SFC, you must open Command Prompt as an administrator. To do this, right-click on the Start menu and select “Command Prompt (Admin)”.

sfc /scannow
The SFC will now scan your system files for corruption and attempt to repair them. This process may take some time, so be patient and do not interrupt it.

To check for Windows updates, click the Start menu and select “Settings”. In the Settings window, click “Update & Security” and select “Windows Update” from the left-hand menu. Click on “Check for updates” to start the process.
If any updates are available, they will be downloaded and installed automatically. During this process, keeping your computer connected to the internet is important.
Once the updates are installed, restart your computer and check if the error has been resolved.
Step 6: Perform a System Restore
If none of the previous steps have resolved the Explorer.exe Class Not Registered Error, you may need to perform a system restore. A system restore allows you to convert your computer to its previous state when it functions properly.
It is important to note that performing a system restore will undo any changes made to your computer since the selected restore point. This includes installed software, updates, and system settings. Therefore, creating a backup of your important files is recommended before proceeding with a system restore.
To perform a system restore, click the Start menu and type “System Restore” in the search bar. Click the “Create a restore point” option from the search results.
