Windows NT 3.51 build 944

This is the only beta of Windows NT 3.51 that was distributed through the Microsoft Developer Network. As Windows NT 3.51 was mainly a bug-fix release (other than the addition of a PowerPC port), the x86, Alpha and MIPS builds offer no major improvements over their Windows NT 3.5 counterparts, minus a change in the branding. However, the PowerPC build is unique, as it is the earliest ported build still available.
