And the technical reason is you cant run NTVDM when the processor is in long mode, because Virtual 8086 Mode cant be run from Long Mode.

  I always thought that was a bullshit excuse. They could have emulated it. Its not like 16-bit apps are on the bleeding edge of performance. Still nobody else is supporting 16-bit applications at all anymore so you have to give them credit.

    > they could have emulated it What's the cost/benefit of that? How much would it cost to build it and how much could they make? You can theoretically do ANYTHING... but a business exists to make money... Why does Microsoft support 16bit? because - without a doubt - someone is paying them for that "extra" support.

      When you make a business decision - don’t pretend it was a technical one. That’s why it’s a bullshit excuse.

        "Technical" is part of the excuse... Don't pretend that the "only" reason a company chooses to not do something is "technical". As I said... there are many reasons - and a company exists to make money. If they decide not to do something that doesn't make them money? It's not a hard reason to see why...
