This will be an ongoing project in which ISO hashes will be added over time. The reason for the creation of this list is for archival purposes, allowing both current and future reference. It was brought to my attention as various sites such as MSDN maintain a similar list but would then often remove older versions which could become problematic. One of the main use cases of this list is for checking files to see if they are legitimate.
The hashes provided will be obtained through a variety of different means; as such this means more hashes will be available on certain files over others and prodomanity they will be for the english language. To keep things simple unless otherwise stated all the files are for some version of the windows operating system.
