That i cant agree with. The Security is XP is lacking in every account. With Vista and even more so in Win7 with UAC a person, especially in school, is so much more protected. UAC is a big help to security, even though everyone hates it. It does so much to help a PC user out but no one is willing to live with a pop up to stay secure.
I'm sorry but I have to disagree with the UAC being a good thing in security.. it is the very first thing that malware bypasses.. it actually gives a false sense of security.
