> I've forgotten more things in this field than I'm comfortable with today. I find it a bit sad that I've completely lost my Win32 reverse engineering skills I had in my teens

I'm a bit younger (33) but you'd be surprised how fast it comes back. I hadn't touched x86 assembly for probably 10 years at one point. Then someone asked a question in a modding community for an ancient game and after spending a few hours it mostly came back to me.

I'm sure if you had to reverse engineer some win32 applications, it'd come back quickly.
