The OS/2 programs were command line only and didn't include the GUI ones. Microsoft removed the OS/2 ability in future versions of NT. Originally it was Microsoft OS/2 NT 3.0 as Microsoft wrote their own version of OS/2 shared with IBM like they did for DOS. But they added the Windows GUI to it and re-branded it as Windows NT 3.1. I think the POSIX was removed as well in a future version. I remember Windows NT 4.0 for MIPS systems, it had some sort of DOS emulation level as well. Microsoft wanted NT to be cross platform and then bailed on it and went Intel only. IBM tried OS/2 for PowerPC systems and it flopped as well.
