First and foremeost, I would like to say, this definetely is a "newbie" question: Is Windows XP considered NT. If so, do NT exploits and vulnerabilities apply to XP? I have XP and want to upgrade by getting the patch, so first I checked what it fixed. Another thing, I see these sites with an exploit followed by a long code that appears as a command string or a programming language (see http://www.emf.net/~ddonahue/NThacks/cpuattacks.htm) what the heck is that? Is that like VB or somethin? How would someone execute that gainst me?
