Fido (short for Full ISO Download) is a free and open-source Microsoft Windows ISO and UEFI Shell direct download address acquisition tool (script based app), developed by the same author of Rufus - Pete Batard from Ireland (written in PowerShell). It is originally designed to be used with Rufus, but can also be used to get direct download addresses of untouched and complete Windows ISO and UEFI Shell from Microsoft official servers.

Fido's purpose is to automate and simplify the access to the official download links of Microsoft Windows retail ISOs and provide convenient access to the bootable UEFI Shell images. With it, you can do that from a desktop client instead of opening a web browser and accessing Microsoft's Software Download page. Of course, they basically performs the same operation as one might perform when visiting the website.

In Fido, users can choose OS Version, Release, Edition, Language and Architecture based on their requirements, then it will call your browser or a third-party download tool to start the download. In addition, Fido also supports command line operation. In short, Fido allows you to be 100% sure that the Windows image you are using is from Microsoft, has not been corrupted or tampered, and is safe and clean to use.
