Windows NT October 1991 pre-release

Windows NT 3.1 build 175.1 is the earliest confirmed build of Windows NT 3.1. It was shown in Microsoft's promotional video from 1991, along with a pre-release build of Windows 3.1. Bill Gates himself demonstrated the new multitasking capabilities that were set to be introduced with Windows NT.

The full string is believed to say "NT 32-bit Windows [NTX86BLD] v1.175". Bill Gates first uses the File Manager to launch the Clock application, then minimizes both to reveal two instances of WINBez running in the background, along with another graphics demo app named simply "Demo" and two command prompt windows.
