Yea... I was looking for something like "Single User Mode" on BSD or the Recovery Console on 2K - XP, but as the only install / boot option, and (unlike "Recovery Console") capable of running most of the command line PE files as DOS with HX DOS extender can, and still allowing for NT Services but with no GDI32.dll, GDI+ display drivers for GFX cards etc.
Just the code OS, that you could use as a "headless server", with only Telnet SSH access or be sat at the keyboard looking at a text screen very much like DOS, and it still provide web, FTP, Gopher, IRC etc services to the internet in the background. So stuff like PS-Tools, net, ipconfig, sc etc would still work. I spend most of my NT Admin time running those tools rather than fighting pointless MSC "snap-in" GUIs anyway.
I wouldn't want to have Notepad work, unless it could be re-written to work via nCurses style UI, though a PE / PE+ build of Edit.com would be nice... the FreeDOS EDIT.EXE one should be easily adaptable... and GNU - Win32 Nano or VIM are always available.
After all. Under any BSD or Linux system there is no reason why you have to start an XServer session. And DOS with HX DOS extender proves that many command line Windows tools work just fine without a graphics driver running... it would be nice to have NT security, task management, threading, multi-tasking, services and scheduling without having to boot graphically... for me anyway.
In short, I guess, I can think of lots of uses for NT without Windows. XD
