Windows NT 3.51 build 944

Windows NT 3.51 build 944.1 is the first beta release of Windows NT 3.51 and the only one that was distributed through the Microsoft Developer Network. It's also the earliest confirmed leaked build of Windows NT 3.51 (not counting build 854.1, as its status is disputed).

As Windows NT 3.51 was a minor update to version 3.5, not many changes can be observed in this build, the most notable being branding changes. However, the PowerPC build is unique, as it is the earliest ported build still available.
