All day on the computer, I actually do not know what this Patch Virtual is, it is no wonder that my brother blame me, I also feel that they know is really too few, and after that should be more to learn some of the. A few days ago, my computer do not know is how it really is very slow, then I would have been there to blame the brand of computer is not good and his brother heard, come and ask me every day in computer work, such a simple question will not do? I said I don’t know, later, my brother said, is to install a virtual patch, he was asked him this virtual patch what is, brother gas do not know to say what good, then give me said once, then give me installed a virtual patch, running the computer a lot better, this also let me feel I know knowledge really is too little.
