Does windows update its firewall protection like NAV2008 or NIS does?

Ok I have NAV2008 and I like it because the firewall type protection. I don't want to use NIS 2009. But if I go to NAV2009 I'd need to sue a firewall.  I was thinking of just using the Windows Vista Firewall which tehy say is better than the XP. My concern though is does windows update its firewall  protection like NAV2008 or NIS does? I know this is a windows question partially, but it plays a role on if I upgrade to NAV2009
