如何从微软Tech Bench下载各个版本系统的ISO镜像文件

微软在Tech Bench官网有关于win10系统各个版本的ISO镜像供广大用户下载，特点是提供了足够的带宽来确保下载速度。但是在默认情况下，并没有提供win7或Win8.1系统的下载。不过，小编接下来要教大家一个方法来从微软官网下载Windows其他版本的ISO镜像文件。

1、为了帮助大家尽快升级到win10，微软启用了Tech Bench升级计划，开辟了更多的带宽方便大家顺利下载win10系统镜像;

2、但是在选择的版本里面并没有提供其他版本系统的镜像下载，如win7/8.1;

3、不过还是可以利用Tech Bench官网的网速优势，下载win7/8.1系统镜像：按F12键;

4、在顶部切换到Console选项卡;

5、然后直接粘贴以下代码：
