AutoRun.inf不光能让光盘自动运行程序，也能让硬盘自动运行程序，方法很简单，先打开记事本，然后用鼠标右键点击该文件，在d出菜单中选择“重命名”，将其改名为AutoRun.inf，在AutoRun.inf中键入以下内容（//后面的是注释，可以不输入）：
[AutoRun] //表示AutoRun部分开始，必须输入
Icon=C.ico //给光盘一个个性化的盘符图标C.ico
Open=1.exe //指定要运行程序的路径和名称，在此为光盘下的1.exe
保存该文件，按F5刷新桌面，再看“我的电脑”中的该盘符（在此为C盘），茄贺你会发现它的磁盘图标变了，还会自动播放光盘下的1.exe文件！
解释一下：“[AutoRun]”行是必须的固定格式，“Icon”行对应的是图标文件，“C:\C.ico”为图标文件路径和文件名，你在输入时可以将它改为你的图片文件所在路径和文件名。另外，“.ico”为图标文件的扩展名，如果你手头上没有这类文件，可以用看图软件ACDSee将其他格式的软件转换为ico格式，或者找到一个后缀名为BMP的文件，将它直接改名为ICO文件即可。
“Open”行指定要自动运行的文件及其盘符和路径。要特别说明的是，如果你要改变的硬盘跟目录下没有自动播放文件，就应该把“OPEN”行删掉，否则就会因为找不到自动播放文件而打不开硬盘，此时只能用鼠标右键单击盘符在d出菜单中选“打开”才行.
