actually never mind, I highlighted everything and chose disable rule. I did this for inbound and outbound rules.
but this spawned another firewall question,
with all the inbound and outbound rules disabled, I can still get out to webpages. I thought that if everything is disabled, i shouldn't be able to do anything.
also, is there a service I can restart to make the changes take effect without rebooting the pc?

Be aware that Microsoft themselves call the concept of blocking outgoing traffic "security theater", read http://technet.microsoft.com/en-us/magazine/2007.06.vistafirewall.aspx

so i read the article McKnife and it's interesting to think that blocking outbound connections through the firewall is just "security theater"
if I understand this correctly, it means that all outbound connection are allowed, unless it is specifically denied. But even if the out bound connection is denied, the guy who wrote the article said that a virus, or malware would just take over an existing out bound connection and use it instead.
is that how windows connections are setup?

"is that how windows connections are setup?" - the technical details can hardly be put in one or two sentences. If there is a virus, it may be so smart not to "phone home" by itself but to instruct a browser to do it for him (as browsers are normally present and allowed to do outgoing connections). How easy that is, I don't know myself, I saw it demonstrated in a video of some hacker congress as proof of concept.
