Microsoft has a new site online covering the security changes in Windows XP SP2. I installed the new build on my Tablet last night and started poking around. Included in the SP2 builds are Tablet-specific improvements to handwriting recognition as well. When you start the computer for the first time you are presented with an Automatic Updates screen before you even see your desktop. On boot there is a window front and center (similar to Windows Tour) reporting on your computer’s current firewall, automatic updates, and anti-virus setup. Security Center is a new control panel, as is Windows Firewall.
