Fix for Base Filtering Engine (BFE) Service Error 1083

When you try to start the Windows Firewall in a Windows computer, you may get a message stating that the the Base Filtering Engine (BFE) service is not running, and any attempts to start the BFE service may result in the error 1083:

Windows could not start the Base Filtering Engine service on Local Computer.

Error 1083: The executable program that this service is configured to run in does not implement the service.

If BFE doesn’t start, many other services fail to start. Windows Firewall is one of those services that depend on BFE.
