为了鼓励大家使用最新的Windows 10操作系统，微软已经关闭了Windows 7、8.1 ISO安装镜像的官方下载，但其实它们都还在，只要绕一下就能轻松获取！

1、打开微软专门提供系统镜像下载的Tech Bench网站。

地址：https://www.microsoft.com/en-us/software-download/techbench

这时候可以看到，只有Windows 10镜像可以下载，而且只有四个笼统的集合版本，不能单独选择。

2、按下F12键打开开发者工具，切换到控制台，粘贴以下代码(来自俄罗斯爆料大神WZor所以夹带了他的广告)：

3、然后按下回车键(Edge浏览器点击播放按钮)，你会发现Tech Bench网站页面里的版本选择框变成了蓝底黄字。

4、点击你就会发现，各种各样的Windows 7、Windows 8.1、Windows 10版本都在这里了，分别有29个、9个、16个之多，什么家庭基础版、家庭高级版、专业版、旗舰版、教育版，什么核心板、单语言版，什么N版、K版、KN版、LE版，想要啥都有，甚至还有Windows 10中国简体中文正版！

5、选择你想要的版本，点击“Comfirm(WZT)”，然后选择语言版本，再次确认，就可以获得下载链接了(都有32/64位俩)，但注意只是临时链接，24小时后失效，所以不能分享。
