This issue can occur if the Windows BFE service is no longer running. The BFE service might also get removed by virus programs or antivirus software. If this happens, you can copy the following registry key from a working machine which has the BFE service, then import it into the affected machine and reboot.
If this does not resolve the issue, please contact your local IT department for further assistance why the Base Filtering Engine is missing or will not start. By default, Windows will have this service installed and running.
Note: The BFE service is only applicable to Vista and later. This service is not applicable to Windows XP.
