Evolution of Windows - Windows NT 3.1

This is the last episode in this 4 episode series, intended to show actual video footage of the oldest versions of Windows. In this episode, it's the first fully 32bit operating system, that doesn't depend on MS-DOS: Windows NT 3.1. NT stands for "New Technology". It offered many security features that any DOS based version could not, and supports networking. This is why DOS was dropped after Windows Millennium, and the NT was used in 2000, XP, Vista and now 7.
