Fido

Fido is a script for PowerShell designed to help you automatically access the official Microsoft Windows retail ISO files. Even though it was initially designed to work with Rufus, the application can also be used as standalone. The advantage of the script stems from the fact that you no longer need to jump from page to page in order to get to the download links, an issue that has irritated many especially with Windows 8 and 10.
It can be argued that you might as well use the Media Creating tool to download and install Windows for your system. While this is true, you should bear in mind that the official ISO files are a surefire way to know that the content has not been altered. Simply put, the Microsoft retail ISO files are 100% clean, have not been corrupted and therefore, save to use.
As far as the modus operandi is concerned, the script performs the same operation you would when searching for the aforementioned files. Once it confirms the links are accessible, the script queries the web API from the Microsoft servers. On a side note, you will be happy to learn that the tool first allows you to select the desired language and only after proceeds to request the download links.
