Windows NT 3.1 build 239 is an early build of Windows NT 3.1 from December 1991. It isn't that different from the October build, but some blue colors have been changed to be darker and this build can work on Virtual PC (although the keyboard doesn't work and causes a machine hang for any keypress).

Like in earlier builds, SoundBlaster configuration is hardcoded for I/O port 0x260 and IRQ 7.
