Unlocking Windows Upgrade Paths

Today, I upgrade a bunch of Windows versions to versions they aren't intended to be upgraded to. Do note that this isn't a comprehensive list, and that most of these aren't my own discoveries. If the ones that are labelled as my discoveries have been discovered before, tell me in the comments and I will leave a pinned comment with updated information.
