Wasn't 64-bit windows 2k/64 itanium-based, not x86-based? If so it would have required supporting existing binaries compiled for a different architecture. My understanding is that the only 16-bit support in 64-bit windows is a few specific loaders for things like 16-bit installers (please correct me if I'm wrong)
- muststopmyths 7y agoYes, the initial 64-bit OS was IA64 and that was the perfect excuse to dump NTVDM, instead of trying to do a W16OW64 or something of that sort. x64 XP and 2003 further solidified that decision because they were "professional" SKUs and Microsoft could dictate that they didn't care about DOS/Win16 for the "new" platform. It didn't exactly run 16-bit installers. https://devblogs.microsoft.com/oldnewthing/20131031-00/?p=2783 https://devblogs.microsoft.com/oldnewthing/20131031-00/?p=27...
