Advice Request Best windows software firewall free or paid?

Please provide comments and solutions that are helpful to the author of this topic.
If you're running Windows 10 or 11, the built-in firewall is very good. Many antivirus also have firewalls, and good ones like Kaspersky. So, what is your antivirus? Do you run W10 or 11? I use Windows firewall with Andy Ful Firewall Hardening and SimpleWindowsHardening. I's a good way to go.

To me "best" in this case is software that requires little or no input from me to set it up and use. Others may have a different definition about the "best" firewall.

Currently I use Windows Defender with DefenderUI 1.02, Interactive Profile.
 
Glasswire without a doubt. SpyShelter Firewall is also very good. I used them both, SpyShelter is a kind of advanced security software.

Hardware Firewalls are good if your on a home network though most routers have a basic one of these. I used to run a separate hardware firewall years ago.
- Comodo Firewall is good though IPv6 needs to be enabled and ICMP rules added. It also has Containment/sandboxing which you'd normally see in a full AV suite.
- Microsoft's firewall is a lot better these days but add FirewallHardening to add block rules for LOLbins etc.
- I echo the GlassWire Pro
- Not tried Binsoft/MBytes Firewall Control yet

Tinywall for me.
Malwarebytes Windows Firewall Control (only used it when it was still Binisoft but really liked it).

I never had a firewall that couldn't recognize the second exe a game uses for the ingame shop till I used glasswire. Last time I check glasswire still wasn't able to keep the A>Z sorting of apps after a reboot. I had to contact them for quite a few things (most of them fixed now) but I never had to do that for the other firewalls I used over the years (in that amount).
 
simplewall by henry++ . written in C, size less than a megabyte

simplewall is not a control UI over Windows Firewall, and does not interact in any level with Windows Firewall. It works over Windows Filtering Platform (WFP) which is a set of API and system services that provide a platform for creating network filtering applications. Windows Filtering Platform is a development technology and not a firewall itself, but simplewall is the tool that uses this technology.
