说明：  安装360之后，系统自带的添加删除程序会消失，但是，如果我们添加删除组件怎么办呢？这个程序就提供命令行下打开添加删除程序。就是一个dos命令：start appwiz.cpl
(Installation 360, the system comes with Add Remove Programs will disappear, but if we add remove components how to do it? This program provides a command line to open the Add or Remove Programs. Is a dos command: start appwiz.cpl)
