I have installed it on a secondary W10 x64 machine, some older Windows build.Version 2.5.7 of the firewall was installed. First of all, if you install it, you have to keep in mind it s a FREE firewall. By default the firewall will not register itself atutomatically, to run at start-up, during installation or after. To enable that you need to enter the interface and check the little box "Start with windows", in the settings, for this to happen. Older builds ,if i remember correctly, were the same.A pop-up dialog for this choice would have been usefull i think. There is a default firewall policy preset for NEWLY installed programs.Default is "Ask for permission".You can also choose "Block All" or "Allow All".Nice feature. Keep in mind that by default windows system exe-s have the "Allow All" policy enabled though.Explorer, Search, Cortana and such are enabled by default to pass thru. The firewall configuration can be protected with a password.Another nice feature, a plus. When you start a program, you will be asked for internet connections, if Ask is your policy of choice.There are 2 types of interaction pop-ups: generic or granular.You either choose to "Allow" or "Prohibit" for each port or ip pop-up-ed, either you can choose the general " Allow All" or " Block All" choices for the App (the smarter way).The granularity in the pop-ups will not translate into granular rules, in the per App settings though.In the per App settings the only things you can define are port numbers and IP-s.This would be usefull to ban/allow,specify exceptions for some IP-s/ports per App.In the menues there is no Direction(inbound,outbound) or protocol to be set (even though the pop-up dialogs will spam you with direction and protocol information). The log is nice and detailed. There is a Block All rule called " Blockade" and a "Gaming Mode".I ve cheked the "Blockade".While in the desktop the feature works, it blocks.At computer restart though, the llmnr traffic, if enabled in Windows, passes thru It"s a basic, free firewall.It has no real granularity in rules editing.I see no way to specify direction of the connections or protocols, even though the pop-ups are quite detailed in information.You can specify IP-s and port number though, if of any use to block/allow some specific IP-s, for an app. It has some usability. If it was designed with simplicity in mind, the granular pop-ups should of been removed.I see no reason for that pop-up spam, if they do not transalte into rules in the per App settings (like you could see in Jetico or Outpost for example). The design aproach is Allow/Block the App, with IP exceptions.There are 2 Block Telemetry options in the menues.I do not know if they work though. Feel free to install it.
