Thanks for the replies. I was never that impressed with the firewall that came with Vista but now I've (finally) upgraded to W7 the firewall seems a fair bit better. I'm currently using Zone Alarm, not because it's any better than Windows firewall but because it's easy to use and seems fairly light on my PC. Might ditch it and use Windows firewall soon.
Since Windows Vista, the XP Windows firewall has been replaced with a technology called Windows Filtering Platform: https://en.wikipedia.org/wiki/Windows_Filtering_Platform
A big advantage for many users is that this WFP comes with an API, giving third parties the opportunity to develop different user interfaces for the firewall.
An example is BiniSoft's Windows Firewall Control: http://www.binisoft.org/wfc.php
This is not a firewall, but a new interface that allows you to configure the Windows Firewall (WFP) in a different way than the default Windows' interface.
There are a couple of other third party applications besides Windows Firewall Control.
