Dave builds the World's Smallest Windows application live in x86 assembly using only a text editor and the command line to assemble the program using the Microsoft MASM assembler.
Whether you're a professional programmer or just curious about how assembly language works, what makes it different from machine language, and why it can be faster and smaller than C you won't want to miss it! Take your Windows Programming to the next level. Or the previous level, depending on how you look at it!

Thanks in part to a suggestion by 'SonicMouse' that I merge linker sections, the current binary size is 1488 bytes... and yes, it runs exactly the same.

PS: For anyone keeping score, two things are certain: (a) it can always be smaller, and I'm down to 1488 bytes now, and (b) Steve Gibson has likely forgotten as much about x86 assembly programming as I know :-). Thanks for the recent shoutout on the podcast!
I realize you can make a much smaller app by simply calling MessageBox, but that's why I outlined what I deem to be the "minimum functionality". SonicMouse has come the closest so far at 1776!
