思路：
1、遍历/Desktop目录下所有.link结尾的文件的具体路径
2、基于这些图标的具体路径和名称，查找图标对应的真实的程序
3、查找对应程序的原始文件名字
4、判断32或者64位系统，来分别获取所有图标的位置
5、把所有的结果放入PMYICON 的结构中
//桌面图标的具体信息
typedef struct{
DWORD num;
TCHAR *pathName[MAX_PATH]; //icon具体路径
TCHAR *processName[MAX_PATH]; //icon对应的程序位置
TCHAR *realName[MAX_PATH]; //对应程序的真实姓名
RECT rect[MAX_PATH]; //对应坐标的位置
}MYICON,*PMYICON;
BOOL Is64Os(){
BOOL bIsWow64 = FALSE;
IsWow64Process(GetCurrentProcess(), &bIsWow64);
return bIsWow64;
}
//通过图标路径获取图标中的具体内容

// 取得装入.LNK 文件的IPersistFile接口
