I am using CFW from the early releases,3 as i remember. And never had any issues on my systems from Vista to windows 11 .As i already mention in my previous post ,CFW is working as it should "at least for me". And btw, if on the software's site (and this is in general) doesn't show compatible with windows 11, doesn't mean that you cannot try the software yourself and see how it works.
PS.I tried few months ago PFW (Privatefirewall) that is more outdated than Comodo and guess what, works perfectly on windows 11.Tested it for a week or so.(sorry for OT).
