Hello can you help me please my windows - firewall is no longer available because some of the settings can not be changed to the Windows Firewall error code 0x8007042c
You haven’t mentioned if you are running any other third party firewalls?
I presume at this point that you only have Windows Firewall.
Does the following link help?
