Again: it is easy to circumvent. Your PFW does not stop _all_ programs
talking to the net without asking first. It does stop those which kindly
agree to be cooperative and do simply use the windows IP stack for
communication. If the program does use other ways of communication (e.g.
your web browser) your PFW won't block nor notify because I assume that
your PFW is configured to allow outgoing web browser traffic. Programs
can also simply deactivate the PFW for a while and send out data anyway.

Again: There is no way to filter _all_ outgoing traffic on the computer
you are running. The only thing to do that would be some external device.
