I’m linking Windows XP SP2 a lot already. It’s pretty sweet. When you try run an app, it tells you if it’s secure (signed) or not.  Actually, not sure about signed apps. I think they just run. Pretty sweet. Installed it last night and it got some extra updates. It won’t talk to Norton Antivirus 2003 though. It might talk to 2004, but 2003 wont tell it anything. Anyway, it’s pretty cool. So far so good.
