Restore Default Windows Defender Firewall Settings in Windows 10  

Please see Firewall Disabled Bug?

I tried setting the Firewall to defaults but the problem remains. Are there any other methods of resetting the Firewall?

No - but I uninstalled Kaspersky Total Security 2 weeks ago which may have corrupted something? I have Malwarebytes Free but only for on demand scanning.

Kaspersky could be a possibility.

Solved - It wasn't Kaspersky antivirus. See post 14 here Firewall Disabled Bug?

Hi Shawn. I have a problem with Defender security. Defender firewall and antivirus appear to be fine but I believe there is a problem with Windows Defender Security Centre.
For example in your option 3 above, all the options in the bottom of the window of Firewall and Network protection example are greyed out and cannot be accessed. In addition, the Security Centre appears to not be able to replicate what the Firewall is doing. In other words it says that it is off, when in fact it is on as viewed by looking directly at the information as indicated in the examples at the beginning of this tutorial. Is there any way I can repair the Security Centre or have you any ideas of what to check. (Home Edition - no group policy).
Thanks

I have used Comodo for some time but around early December when I updated to 1709, Comodo updated as well which resulted in errors in the Event log that according to Comodo have been sorted with the latest update - which they have not. As a result I thought I would try the Microsoft Security and disabled all the options in Comodo. The Defender software took over and updated the antivirus and is running ok. However, the Defender Security Centre tells me that no firewall is in operation but Defender Firewall says it is. In fact the Security centre says that I must enable Comodo Firewall as I am not protected. When I enable the Comodo Firewall the Security centre tells me everything is fine and Windows Security then tells me that both Firewalls are in operation! Totally confused!
