16-bit Assembly on 64-bit Windows?

Question

I decided to start learning assembly a while ago, and so I started with 16-bit assembly, using FASMW. HOwever, I recently got a really new computer running Windows 7 64-bit, and

My advice would be to just write 32-bit code. While it might initially seem like it would make sense to learn how to write 16-bit code, then "graduate" to 32-bit code, I'd say in reality rather the opposite is true: writing 32-bit code is actually easier because quite a few arbitrary architectural constraints (e.g., on what you can use as a base register) are basically gone in 32-bit code.

For that matter, I'd consider it open to substantial question whether there's ever a real reason to write 16-bit x86 code at all. For most practical purposes, it's a dead platform -- for desktop machines it's seriously obsolete, and for embedded machines, you're more likely to see things like ARMs or Microchip PICs. Unless you have a specific target in mind and know for sure that it's going to be a 16-bit x86, I'd probably forget that it existed, just like most of the rest of the world has.
