It would be nice to make when installing CFP automatically disables Windows Firewall, so the two of firewall, as two anti-virus, can interfere or even lead to a BSOD :o. For beginners, it will be very useful. 
:-TU
I think a more preferable implementation might be a prompt on first run, and perhaps a toggle somewhere in firewall settings. And… if the latter is the case as well, a note in the prompt telling the user where to find the option (for future reference).
I hate to play Mr.Anecdotal-Evidence, but of the five computers I’ve been running with CIS, and windows firewall running simultaneously, none of those computers have experienced a BSOD in the past year… well… it’s gotta be getting close to a year at this point. And god knows whether that old BSOD was caused by CIS and Windows Firewall getting in the way of one another. (2 WinXP, 3 Win7)
Anyone have something objective to point to, regarding the whole multiple firewall issue?
Only that everybody suggests doing so…
Even Microsoft (at least with Window XP) has a warning in the security center that running two software firewalls can lead to problems.
That said, on some systems, CIS installation does turn off the Windows firewall. I don’t know the requirements, but I’ve installed CIS on my computer, and two for my sister. One of her machines had the firewall turned off automatically.

That warning you will see in all of the Windows OS(from xp and above. I don’t know how it is with Windows OS lower than XP).
ZA-firewall in an exeption and it’s also recommended to have Windows firewall on; ZA doesn’t start at boot (as far as I know ) and you are therefore vulnerable during the activation time.
