Is it necessary to have this service running if I don't have any shared folders/files, and File and Printer Sharing is not enabled? I'm running
WinXP SP3 with all current updates
Athlon 64 x2 Dual Core 4800+
415GB HDD free space

There seems to be a time delay opening email and IE when both ZA and Windows Firewall are running that's not there when WF is turned off.
I thought in the earlier releases of ZA that WF was automatically turned off, but I don't see that recommendation any more.

Thanks for your time
