Release Notes


  • Changed the "single instance detection" code to something supposedly more reliable (and the code is cleaner and easier to understand that way, no more Mutex and cross-processes messages). It should help getting rid of the "omg there are thousands of notifier.exe processes trying to kill my computer" syndrome ;-)
  • Added an option to minimize the console to the system tray (check the notifications options)
  • The notification will now remember if you lastly displayed the detailed dialog or the simplified one. I think it's more user-friendly this way than using a dedicated option.
  • Some other minor tweaks.
  • Edit: I forgot to tell I added a way to copy the information from the notification as well. Just right-click on pretty anything to get a menu (only copying is possible as of now).

Known bugs

If you open the console with an admin account (not the one you're logged in with), the settings (animation & alike) won't be applied for your logged-in account. I'll fix this another day...

About this version

Keep in mind that I only tested this version on my computer. It may not work as expected on yours, this is what beta versions are made for...
Feel free to tell if you encounter any bug.
Please note that the log is more verbose with this version (I'll change it for the next stable release, but I need some feedback first).

About you, fellow users

Everything I do, I do it for you... (sounds like bad lyrics).
Hope you'll enjoy this version; if not, feel free to tell constructively ;-)
As said, I can't answer every time, but I'm reading all and every message I get.

Worked great on my win7 machine for several years now, and I'm so happy it's been released for my main 8.1 machine---long wait. Not a single glitch to report! I feel sorry for the newbs who voted one star, who have no business rating computer software. I'm surprised they know where the start button is. Only question regarding this program is why console.exe tries to phone home? Had to put a block on that as ironic as it may be lol. Anyhow, thanks again!!...............................UPDATE: March 24. RE: authour's request for feedback. It's true that initial setup can be tricky (a lot of cryptic processes ask for access). What I found was that most of the individual processes which initially ask for access, do not do so when the parent service "Host Process for Windows Services" is allowed access. When WHPFS is allowed as an exception, you can then delete all the other sub services which initially asked for access. The result of doing this is the reduction of 10 or 15 services asking for access, down to 4 or 5. What to FIX: ability to write 2nd reviews under same account, allow line breaks in reviews (look how it's all crammed together lol). I will donate soon. Thx! :)

Thanks! While I kinda agree regarding noobs questions and "reviews", I can't publicly tell I do, would be inappropriate ;-) Regarding Console.exe phoning home, it's checking for updates (only looking for a text file containing version information). I'll turn that into an option because it keeps getting people wonder if I'm not stealing personal data :-) Thanks again!

WFN is extremely handy utility! Even enterprise level software firewalls don't provide notifications (interactive mode) with Win 8.1. It's my first day of usage and I'm very pleased.
by borax on Mar 16, 2015 at 12:31 AM
Thank you very much! There still are some flaws with Win8/8.1(notifications are displayed on the standard desktop and never over the start screen), but with Windows 10 around the corner I really wonder if it's worth fixing that...

WFN concept is pretty good but there are some design issues. 1. Notifying on blocking rules. 2. Service name is not the same as in Task Manager. 3. Open up advanced mode every time a popup is shown. I found that there is a lack of connection between the notification and the set of rules in 'Windows Firewall'. This result in adding rules every time instead of enabling or modify existent rules. When using WFN I constantly looking in the 'Event Viewer', 'Task Manager', Windows Firewall with Advanced Security', 'Windows Firewall Notifier' and 'Whois IP' (in the browser) when I need to make a change. Ideal situation would be to display blocked info and find closest matched rules in the same window. And as an extra bonus integrate tools like 'whois ip'. When using the program it dose not feel snappy/fast in general. A redesign and rewrite in C++ possibly would make it better, (maybe).
by pelle2004 on Feb 26, 2015 at 10:20 AM
Thank you for your comment! My answers: 1. This is due to Windows logging blocked connections the same way whether they are blocked by default or by a rule. I have to check the rules list everytime to verify if a notification has to be displayed, and obviously it does not work as expected for some users. I need some exemples to sort it out. 2. Will check that :-) 3. Advanced mode should only show up if you enabled it previously (it should remember its state). If not, then this is indeed an issue I'll have to look at. Regarding your other comments / issues, I'll have a look at it. For performance, I was not aware it was laggy, can you please give more details about what part gives you this feeling? Thanks!

Uninstalled this because alerts did not work, but uninstall script did not work either. Later I installed Comodo Firewall & Comodo alerts show WFN is still running, interfering with network connection. Good luck trying to get rid of this thing.
by bugmenot2 on Feb 25, 2015 at 8:33 AM
Hi, thank you for reviewing "this thing"! What do you mean by "interfering with network connections"? Because this is definitely not how WFN works. And what did the disabling script tell you? Did you try disabling notifications through the options menu instead? Did you open an issue about that so that it can get fixed (looks like you didn't)?

Neat little firewall tool, but this version contains some flaws. 1) When a block rule exists, the notifier still shows blocked connections, although catched by this rule. This causes the notifier to permanently show up for no reason, and, when selecting block again, creating duplicate rules. 2) the service field shows nearly always multiple matches, although most of the time only one or no service (labeled as "not available", roughly translated) shows up in the detailed window. 3) still having performance problems, when many connections are blocked, hundred of processes spawn, driving the CPU to 100% usage and rendering the machine unusable. If you could address these issues, WFN would be the very best firewall tool there is!
by DevCybran on Feb 21, 2015 at 1:47 PM
Hi, thank you for your feedback. Sorry about the 100% CPU issue, I thought I definitely got rid of it in this version. There is only one way to prevent this: having an always-running agent in the background. Maybe I will switch to this solution, as it would help fixing some other issues as well. Regarding the services detection, I know it's far from perfect, but it should be usable the way it is implemented. When it shows as "not available" (which is not a rough translation, if shown that way), it means that the service detection routine failed detecting any service for the given connection (which usually occurs when the parent process exited before WFN was launched). This is a tricky part, and only a bg agent would be helpful here...

Love it being open source, i hope this project keeps active. Best firewall i have used in windows since long time!
by th3m on Feb 19, 2015 at 9:10 AM
Thank you very much! While it's not as active as I'd like it to be, I'm still working on it when I get some free time (like, say, once every four months, usually :-/). I'll have some next month (having to stay home for a while), so I should be able to fix some bugs.

Excellent as far as what it does and I'd say good for how it fare doing it. Thank you so much for working on this software I love it. Only problems I have is the occasional crash of the UI (never the pop-up UI, only the Console) and in some instances I opt to apply a rule for all future occurrence but it ask me again and again.
by Err0r4o4 on Jan 21, 2015 at 5:24 AM
Thank you! Can you please grab the error.log file when the console crashes and open an issue with the same file attached? For the other issue you mention, many users are facing the same so I'll fix it asap. Thanks!
Reply by Wokhan (N/A) on Mar 16, 2015 at 9:23 AM
I just tried an pleased with this release. BTW, when removing a rule, please move the cursor to the item before or after the removed one, instead of just return to the first row of the list.

Lightweight, integrated with windows task scheduler. Best windows firewall outbound notification software I have ever used. Slick design by using firewall security events in task scheduler to pop up notifications when an outbound connection is attempted by some piece of software, that is not already regulated by rules in the built in windows firewall.

Thank you very much for your review :-)

Wokhan, thanks for your service. Constructive user here, trying to help find bugs and improve the program. Please review the issue at for more details on this error. Appreciative user, trying to get the program working again. Notifier.exe process is running, but notifications do not appear. The error log: "SYSTEM - [ERROR] - Unable to initialize WFN This single-instance application could not connect to the original instance. at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run(String[] commandLine) at WindowsFirewallNotifier.Program.Main(String[] argv)" Thanks for pointing out the added verbosity in logging.

Edit: I'm pleased to see you updated your review with such a constructive feedback :-) Thank you for the rewording and complementary information you are providing, I'll have a look at the issue you mention as soon as possible (should get some free time around Christmas). Stay in touch :-)
Reply by Wokhan (N/A) on Dec 13, 2014 at 1:42 PM
The release appears pretty stable. I am running as non-admin and therefore WFN is accessed via an elevated session. One problem discovered when pressing Locate under Logs and I can an exception. Reported under issues Paul
by OldCole on Nov 25, 2014 at 11:15 PM
Thanks for noticing this issue. I'll investigate and fix this when I get some free time (can be in a while unfortunately :-/ ).

Great software, works fine and doesn't gobble up system resources. The best software to harden Windows Firewall so far! Keep up the good work..Cheers!
