But how exactly does it help you? How can limiting connectivity & changing your firewall settings from previously set help you exactly. I'm eager to learn exactly what advantage you find out of using SP2 for the web. If you're having anything to do with gaming, phone or video conferencing then you'd find SP2 a major headache I'm sure. It's caused headaches in business, schools, home, etc. as well loss of a considerable amount of money.

If you want good security then get a good, decent firewall. Backed up with AV, adaware & spyware.
