Windows NT 3.5 (originally codenamed Daytona) is the second release of Microsoft's Windows NT line of operating systems, and was released on September 21 1994.

Overview

---

This is the first Windows NT to adopt the names Windows NT Workstation and Windows NT Server for its editions. The editions of the previous Windows NT release, Windows NT 3.1, were named Windows NT and Windows NT Advanced Server. The screenshot shown is for the Windows NT Workstation release.

The new key features in Windows NT 3.5 included the new startup screen, no longer being a black DOS box lookalike and the interface was changed to the same as that for the Windows for Workgroups 3.xx series to maintain consistency between these two operating systems. It also included far better Object Linking and Embedding (OLE) support and was more efficient - performance was higher and it required less memory.

In July 1995, Windows NT 3.5 with Service Pack 3 was rated by the National Security Agency as complying with TCSEC C2 criteria.

Trivia

---

• One of the primary goals during NT 3.5's development was to increase the speed of the operating system; as a result, the project was given the codename "Daytona" in reference to the Daytona International Speedway in Daytona Beach, Florida.
• The x86 version of Windows NT 3.5 will not work on a processor newer than the original Pentium (P5 core). Pentium Pro, Pentium II, and later processors are not supported.
