   Ah-ha, right, that was the source of the confusion. It's a reasonable   
   mustake, 32-bit Windows *could* run DOS programs using virtual 8086 mode   
   (a sort of emulation), so your program would have just worked!

   I feel your frustration, but you're trying to jump in at the deep end   
   with native win64 assembly language. This is just opinion, but I think   
   starting with C or C++ would be a better option. If you want to learn   
   assembly as you go, you can examine the code the compiler generates and   
   try to follow along with what it's doing.   
      
   One fun tool you can look at is compiler explorer, take a look:   
      
   https://godbolt.org/z/WW3383   
      
   You write some C on the left, and it shows you nicely formatted   
   assembly on the right. You can try changing something, and watch what   
   happens to the generated code.
