回複：不能不防——當心Windows XP的“自動更新”

It happens only the first time when you install windows XP system with the Internet cable connected on your computer, upon finish, the computer will ask you if you'd like to go online updating, if you press OK, Mocrosoft will check your product key number first, when they find your software is illeagal, a program will be downloaded to your computer, and it acts exactly this same way as you said. It is very easy to be solved. Remember to disconnect Internet cable before installing Windows XP system.
