软件：驱动精灵2.02
简介：驱动精灵是一个非常实用的驱动程序备份工具，经常重装电脑的人一定有找驱动程序的经验，要不就原版驱动程序已经不见了，就是事先没有备份起来，找起来相当费时；现在你只要利用驱动精灵的驱动程序备份功能，在电脑重装前，将你目前电脑中的最新版本驱动程序通通备份下载，待重装完成时，再试用它的驱动程序还原功能安装，这样，便可以节省掉许多许动程序安装的时间，并且在也不怕找不到驱动程序了。
平台：
操作系统: Microsoft Windows XP
系统补丁: Service Pack 2
工具：OD1.10，peid，lordpe，importREC
软件出来很早了，注册算法又简单，估计注册机已经满天飞了。忙于工作，拿来练练手，热热身。
开工：
1、 准备工作：安装完毕后，运行，出现注册对话框，随便输入点什么，注册，有注册错误提示。
2、 查壳，UPX，脱之。
3、 载入脱壳后程序，搜索Messagebox,下断。
断在这里：
