What causes the Error 0x8004100e?

Several factors can cause the error code 0x8004100e to appear on your PC. Some are:

  • BitLocker WMI class (win32_encryptablevolume) is not registered – The error can occur due to the BitLocker WMI class not being configured on your PC. It prevents the services relying on it from accessing and causes the computer not to communicate with the MBAM server. Hence, it fails to send the encryption status data.
  • Cluttered Windows Registry – A clustered or unorganized Windows Registry can cause errors. It prompts the registry keys needed for the communication between the MBAM server and the computer to be unreadable.
  • Faulty entries of non-existent programs – Improper software uninstallation can cause missing or corrupt entries from the non-existent program. Also, it can cause missing files that were accidentally deleted from the registry to corrupt system files and cause the system to malfunction.

These factors may vary on different computers. Nevertheless, this guide will take you through effective ways to resolve the 0x8004100e error message on your PC.

How can I fix Error 0×8004100e?

Before proceeding with any advanced troubleshooting steps, go through the following:

  • Turn off background apps running on your PC.
  • Temporarily disabling third-party antivirus software.
  • Restart Windows in Safe Mode and check if the error persists.
  • Install a Registry cleaner – Use registry cleaner software to scan for clustered keys if the above steps are not working.

If you can’t resolve the error, try the solutions below:

1. Perform a clean boot

  1. Press Windows + R key to open the Run dialog box, type msconfig, and click OK.
