微軟在Tech Bench官網有關于win10系統各個版本的ISO鏡像供廣大用戶下載，特點是提供了足夠的帶寬來確保下載速度。但是在默認情況下，并沒有提供win7或Win8.1系統的下載。不過，小編接下來要教大家一個方法來從微軟官網下載Windows其他版本的ISO鏡像文件。

1、為了幫助大家盡快升級到win10，微軟啟用了Tech Bench升級計劃，開辟了更多的帶寬方便大家順利下載win10系統鏡像;

2、但是在選擇的版本里面并沒有提供其他版本系統的鏡像下載，如win7/8.1;

3、不過還是可以利用Tech Bench官網的網速優勢，下載win7/8.1系統鏡像：按F12鍵;

4、在頂部切換到Console選項卡;

5、然后直接粘貼以下代碼：
