Python获取计算机已安装软件的软件名列表

糊涂虫晓晓

从网上和站内找了好久，没找到正儿八经的获取已安装软件列表的好代码，只能自己动手做一个。


前提：1、已安装软件，是下一步下一步下一步那种安装到电脑上的，什么绿化版 、绿色版、单文件都不算在其内。
2、本编程纯属我自己这个python菜鸟仿照网上大神VB.net做的。
3、只获取了软件名列表，不获取版本，换言之，软件名一样版本不一样的，也在去重范围内，只会留一个。（所以和你卸载程序里的数量应该相差个位数）
4、本程序在去更新时会略有瑕疵，望大神有现成的完整好代码能在回复区贴出来。（C#和Python都可，其他的我就看不懂了，可以给其他人看）
5、从最后的with open可以看出我把获取的列表存在D:\GetSoftware.txt里了，大家运行完一遍可以去那里找找看。
废话不多说了，直接上代码，菜鸟可以用来学习，大神修改作为他用都可。

你这个错误，我要是遇到的话，解决思路是这样的：第一，print列表ExistingProgramList试一下，看看正不正常，不正常说明获取软件列表就出了问题，里面是乱码，就在存入字符串的时候就把字符串的编码调一下，这里可以设断点可以print，就能看出了，第二，如果列表输入没问题，说明文件打开写入有问题，在重新建一个py文件，单独写入字符串或者自建一个列表写入试试，这两步做完应该就没问题了。

这是我们直属领导的要求，让我做个东西，分发下去，让他们每周运行一次，获取他们都安装了什么软件，有没有游戏什么，本来还要弄个游戏名的池子，进行判断，懒得弄了，一步一步来

你把编码改为GBK试试，我是用的Pycharm，但是因为要连sqlserver数据库写入中文，所以把Pycharm的全局变量改为了GBK也可以是CP936，两个是一样的东西，你改改试试。

看到这个原因，感觉领导太......吧。

前一段网上热议的，离职分析监控系统；下班前在群中发每个人手机各程序用电量信息。感觉这样的领导毕竟是少数。

没想到这又冒出一个。
