I see. Not an issue then. I would disable the firewall anyway. Don't want a software firewall, my Network is already stealth.
Again, I just went and read all the new features with SP2, and I still can't find one single reason why I should bother:
1. Help protect your PC from harmful attachments.
By alerting you to potentially unsafe attachments, SP2 helps guard your computer from viruses that can spread through Internet Explorer, Outlook Express, and Windows Messenger.
(No thank you, I'll decide what's harmfull or not. If I want to send or receive an EXE by email, I like to be able to. I already have disabled this "feature" in Outlook.)
2. Improve your privacy when you’re on the Web.
SP2 helps protect your private information by applying the security settings that guard your PC to the files and content downloaded using Internet Explorer.
(Not sure what that means but it sounds scary. Again, I don't want Windows or IE to decide for me what I should download or not. Windows should quit being so intrusive, let me have the control.)
 
3. Avoid potentially unsafe downloads.
Internet Explorer download monitoring and the Internet Explorer Information Bar warn you about potentially harmful downloads and give you the option to block files that could be malicious.
(Again, see #2)
 
4. Reduce annoying pop-ups.
Internet Explorer Pop-Up Blocker makes browsing the Internet more enjoyable by helping you reduce the unwanted ads and content that pop up when you’re browsing the Web.
 
(OK, cool, but I already have Google bar. Does a fine job.)
5. Get firewall protection from startup to shutdown.
The powerful, built-in Windows Firewall is now turned on by default. This helps protect Windows XP against viruses and worms that can spread over the Internet.
(No thank you. Don't want a software firewall.)
 
6. Take control of your security settings.
The new Windows Security Center allows you to easily view your security status and manage key security settings in one convenient place.
(Not sure what that means, I can change the anti-virus options in Norton. I doubt this Security Center will be able to change my router settings.)
 
7. Get the latest updates easily.
Enhancements to Windows XP’s Automatic Updates feature make it even easier to access Windows updates. Plus, new technology has been added to help dial-up customers download updates more efficiently.
(How can it be easier? I go to Windows Update site and it tells me what I need. I don't want more than that. I have the automatic updadtes already diabled because I like to go myself manually. Again, I hate when things are done automatically behind my back. I like to have to keep the control of my PC.)
 
8. Help protect your e-mail address.
Improvements to Outlook Express help reduce unwanted e-mail by limiting the possibility of your e-mail address being validated by potential spammers.
(Not sure what this is. Sounds like a cool thing, but unfortunately I don't use Outlook Express, but Outlook.)
 
9. Take action against crashes caused by browser add-ons.
The new Add-On Manager in Internet Explorer lets you easily view and control add-ons to reduce the potential for crashes and enjoy a more trouble-free browsing experience.
(OK, sounds fine. But I read somewhere that you can't uninstall unwanted plugins, only disable it.  I would like to have a real plugin manager where i can remove the plugins and third party toolbars I don't want not just disable them.)
 
10. Go wireless without the hassle.
SP2 improves wireless support and simplifies the process of discovering and connecting to wireless networks in your home or on the road.
(My wireless works fine right now, never have a problem.)
 
Overall I find more reason NOT to install SP2 than reasons to install it.  I guess eventually I'll have no choice as I'm sure there will be software that may require it. I'll see then.
