Usually, if they are not excepted, then they are already blocked.
Note that the XP firewall is mostly intended for blocking incoming requests,
not outgoing - if your machine asks for something, it does not block the
initial request, or the reply to that request. If that same request was
initiated from outside, it may be blocked.
Ports that are not blocked by default usually need to be left open for
something important to work.
Some traffic may not be TCP or UDP, and may not not use ports.
What are you trying to block / stop? There may be another way.
