Symptom:
The error message "Windows Firewall can't change some of your settings. Error code 0x80070424" will pop up when you try to change the Windows Firewall settings. In the meantime, when you restart the system, it might pop up an error saying that "Base Filtering Engine Service" could not be found in the system.
Please note that the same error code could pop up when you try doing anything in Windows Defender.
