How do I remove a password if I have forgotten it?
You will need to boot to Safe Mode to remove a password configured in Sunbelt Personal Firewall. You may skip steps 1-6 if you already know how to boot into Safe Mode.
Click on the Start button and go to the Run line.
Type "msconfig" without the quotation marks and click the "OK" button.
In Startup Selection on the General Tab, select the option for Diagnostic Mode Startup.
Click the "Apply" and "OK" buttons.
Restart Windows.
Windows should now pause during the boot process. You should see a list of startup options. Choose option number three, Safe Mode.
Open My Computer and then your hard drive. Go to Program Files \ Kerio \ Personal Firewall4.
Open the folder named config.
Delete the file named kpf.cfg.
Before rebooting Windows you should rerun the "msconfig" command and set the "Start up Selection" to "Normal Startup" or "Selective Startup."
Reboot Windows into Normal Mode.
Deleting the kpf.cfg file will remove the password configured in Sunbelt Personal Firewall and it will reset all of the settings within the firewall.
В двух словах: грузишься в безопасном режиме и удаляешь kpf.cfg. Т.к. в этом файле хранится текущая конфигурация, то сбросится не только пароль, но и настройки станут по-умолчанию.
