Some of the old software before 2010 may not be able to install/run normally on x64 or Windows 10 systems. Be aware of it before purchasing it.
Windows NT 3.50 is the second release of the Microsoft Windows NT operating system. It was released on September 21, 1994.
NT 3.50 still used the Windows 3.1 desktop.
Windows NT 3.50 did not support laptop computers as it had no drivers for PCMCIA adapter cards.
Windows NT 3.50 refuses to install on a processor newer than the original Pentium (P5 core). Windows NT 3.51 fixed this.
Windows NT 3.50 was finally succeeded by Windows NT 3.51 in 1995.
