The ones that result from a Media Creation Tool are less bloated but still perform the task properly.
Those ISO’s are larger than a standard single-layer DVD can hold and must be cut to a dual-layer DVD. These files can also provide the ability to create USB drives for the same purpose and also can directly allow users to install new versions onto their properly working systems without any intermediate steps (cutting an ISO to disc or creating a finished USB drive.) Another perk is that ISO files from a Media Creation Tool are significantly smaller than those which can be gotten upon release from Microsoft. The most efficient way to access official ISO files is through the official Media Creation Tools which Microsoft hosts.
