Important note
While I hate having to write this, I am seeking for some funds to help me work on personal projects. I promised I'll keep WFN free for everyone, and I will, but if each of those who downloaded this soft gave as little as 1$, it would have been really helpful, as you can guess. Of course I am not forcing anyone and I know many people who need the exact same dollar to survive, but I have to give it a try.
On a side note, I'll be able to work on WFN very soon (even if you chose not to donate ;-) ), I'll keep every commenters and reviewers in touch (expect some feedback next month).
Again, thanks to those who already donated (that's maybe 10 users over the 75 000 who downloaded WFN on all websites, so those ones know how precious they are ^_^).
If you feel generous, you can head to PayPal.
Thank you and sorry for this message!

Version has been released!
It's a beta (again), I think v1.9.1.9 was not good enough to be released as stable, but went with another beta instead... :-P
I need your feedback on that one, especially regarding the issue with the army of Notifier.exe processes lying around in some cases. You should only see one or two of them now...
Thanks :-)
Edit (2014.11.21): Come on guys, almost 500 downloads for this version and only one feedback... At least tell me if everything's alright :-P

Project Description

Windows Firewall Notifier (WFN) extends the default Windows embedded firewall behavior, allowing to visualize and handle incoming or outgoing connections.

I finally decided to give the code to the community (as many people asked me too, and since I do not have that much free time to keep working on it).
Enjoy ;-)

Please note that WFN started as a personal project, not meant to be fully distributed, but ended up with more than 65 000 copies being downloaded all around the world along 2012 / 2013 (I guess I should have sold that one :-P). Therefore the code is not commented as it should be (as of v1.8.0) and some parts of the application should probably be improved / rewritten from scratch.


WFN requires Windows Vista or later (Windows 7, Windows 8).
Please do not ask for a Windows XP version, since WFN relies on features introduced with Vista, it would require too much work. Well, now that it is open source, maybe someone will port it but keep in mind there are great alternative out there.


Download it, unzip it, launch it using Console.exe and you'll see ;-)
This application only uses existing Windows features, enabling some of them when first launched:
  • Enables the Windows embedded firewall
  • Sets the firewall to block both inbound and outbound connections for which no rule exists
  • Enables the default Windows firewall inbound connection notification
  • Enables the Windows firewall outbound connections logging (disabled by default)
  • Creates a scheduled task linked to the Windows firewall event log entries, allowing Windows Firewall Notifier to be launched when needed only
