Use netsh in Windows 7 to export firewall policy using command line.
Open an elevated command prompt and type the netshell command below.
netsh advfirewall export d:\myfirewall.txt
If everything works fine it will display "Ok."
It's exported using a filename with ".txt" extension, but the output is not readable using any text editor.
You can save the file to a USB drive as a backup or import the firewall policy to another computer.
To import the exported firewall policy use this command:
netsh advfirewall import d:\myfirewall.txt
Just replace the word export with "import" and specified the path location of the file.
A very simple way to export firewall policies.

If you don't like doing it using command line, exporting firewall policy can also be done using GUI.
Open "Windows Firewall with Advance Security" and look for "Export Policy".
