Hijacking this thread - if anyone used the official media creation tool to get a x86_64 Professional ISO, can you please post MD5/SHA1 hashes? Mine don't match anything on google.
"Note that the file hashes (CRC32, SHA1, MDA and etc.) for Windows 10 ISO images created by Media Creation Tool are unique as time stamps and other factors are different for each computers."
The tool doesn't just download some ISO, it actually downloads a lot of different files and then transforms the content it downloaded using the user's CPU and resources, producing the wim files that would finally go to the media. Why, I don't know.
