NTVDM exists and simple non-graphical DOS stuff works fine but only in a window, full-screen is completely disallowed (driver issues due to new WDDM driver model or whatever). This is not local to my copy of Vista. You have to use something else (e.g. DOSBox) if you want graphics. However, Win64 (any version) lacks V86 mode, so no 16-bit stuff (DOS or Windows) works there (except via cpu emulation like DOSBox or what DOSEMU supposedly does).
