获取windows已安装程序
主要是从注册表中获取。根据系统位数不同有两个路径。
32位系统：
HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall
64位系统：
HKEY_LOCAL_MACHINE\\SOFTWARE\\WOW6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall
控制面板中的卸载程序显示的是能卸载、更改和修复的，而设置–应用与功能中显示的是除系统安装之外的软件。
程序 SoftWareInfo.cpp：
#include 头文件自己找一下

我提供了2中方法都可以，其中用到的几个重要的注册表项：
SystemComponent 系统组件
WindowsInstaller windows安装
NoRemove = 1 禁止卸载
NoModify = 1 禁止修改
NoRepair = 1 禁止修复
其中控制面板中的卸载软件显示的是过滤后的，只有当：
(NoRemove == 0) || (NoModify == 0) || (NoRepair == 0) == 1
(dwSystemComponent == 0) && (dwWindowsInstaller == 0) == 1
UninstallString(注册表项卸载路径)不为空的时候。
这三条都成立后显示的才是控制面板中的卸载软件中显示一样的。
