So, I'm confused. Many people releases the SHA1 for some ISO that supposedly came from Microsoft (or copied or whatever). But anybody who is offering untouched stuff, is offering the Actual folder, of which you must create your own iso. I may not understand the ISO format hence my question that if I was to create my own ISO of the folder contents that are genuine from MSFT (unchanged) will I get the same SHA1 as if they created their ISO? So in short, is creating ISO's a universal process regardless of software you use, yada yada? If that is true, it makes me even more doubtful of authenticity (not that I am doubting, but it makes wonder), that if creating an ISO today, and creating an ISO 10 days from now, and creating an ISO with Software A vs. Software B is all the same, then somebody could easily create an ISO of their Windows folder that they got from somewhere from Microsoft and edit it or something and then make an ISO, give it's SHA1. Am I making any sense?
