Vista/Win7 do have firewalls enabled by default, but the first time the machine detects it is connected to a new network it asks what kind of network you are on. The options being Public, Home or Work. If the user choses "Home" the firewall is effectively disabled as all of the SMB/NBT ports are opened up, as well as several ports for media sharing.

I believe it is mostly for the local subnet also...the 'home' is called 'private' on professional editions and the expectation is that you are on a private internal network. There is always *some* IPv6 traffic denied in all 3 modes - I haven't had the opportunity to test or look into the specific differences.
