That it does... but you're thinking way to logically.

People want to share files and run bittorrent clients (which test for them to have an open port in many cases). Disabling the windows firewall is extremely common.

I spent almost 2 years doing student support... and XP SP2 came out during that time... I'm willing to bet for every 100 students we saw, maybe 5 of them had the firewall turned on.
