使用python实现对windows软件包的安装和卸载

xiaoxue85

　　在对windows安装包产品进行测试时，安装和卸载是难免的，并且人工的手动安装和卸载会花费大量的精力和时间，为此需要编写一个脚本来实现对windows安装包产品的自动卸载和安装。
　　首先参考了 http://www.iyunv.com/TankXiao/archive/2012/10/18/2727072.html#msiexec ，该博文详细讲解了使用msiexe命令进行卸载的内容，同时提供了使用C#实现的卸载程序。对此，我想到了使用python编写脚本实现类似的功能。主要的算法大致是使用软件名称去注册表中搜索到该软件的包括productCode在内的uninstallString，而后根据这个字符串进行默认卸载，再根据软件的msi包路径进行默认安装。小弟菜鸟一枚，初次编写脚本，望大家多指点。
