After installing some programs, they appear in the "Set Your Default Programs" list. Selecting one of these and clicking on "Choose defaults for this Program" brings up a list of all extension and internet protocols known to the program.

Where exactly in the registry is this information stored? In other word, how does Windows know which programs to put into the initial list, and which file types and protocols to put into the second one?

(Note: This is the inverse of this question.)

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    It is not the inverse of the question that you have linked. It is a duplicate of that question. Windows doesn't store the information twice in the Registry. – Chenmunka Mar 16 '15 at 14:59
