They're not encoded, but the code blocks are shuffled. That's why disassembly does look straightforward, but it used to thwart BinDiff at the time.

    It was a part of our Windows build process when I was at Microsoft. I only assumed that they would keep doing it, but they might have as well dropped the practice.
