After reviewing several other sources, notably from Morgan and Norris, I’ve decided that Joachim Metz’s Windows NT Registry File (REGF) format specification is the clear winner when it comes to laying this information out in a clean, clear, easy to read format. Metz doesn’t have all of the answers, but unlike the other documents, this one is actively maintained as the libregf libraries are maintained, which is kinda awesome! This means that as we find these answers, this document will become more comprehensive. (side note: if you have some free time, check out the other projects he’s working on and you’ll quickly see why he is one of my favorite people.)
