Windows NT 3.5 is the second release of the Microsoft Windows NT operating system. It was released on 21 September 1994.

One of the primary goals during Windows 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.[1]

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.

New features in Windows NT 3.5 include VFAT, support for I/O completion ports [2] and the Microsoft DHCP and WINS clients and DHCP and WINS server [3] It featured a new startup screen. The interface was updated to be consistent with the Windows for Workgroups 3.xx. It also upgraded Object Linking and Embedding (OLE) support from version 1.0 to version 2.0 and is more efficient - performance is higher and it requires less memory than Windows NT 3.1.

In July 1995, Windows NT 3.5 with Service Pack 3 was rated by the National Security Agency as complying with TCSEC C2 criteria.[4]

Windows NT 3.5 refuses to install on a processor newer than the original Pentium (P5 core).[5] Windows NT 3.51 fixed this. It is however possible to modify files on the install CD which will allow it to install.

"The first release of Windows NT was larger and slower than expected, so the next major push was a project called "Daytona", named after the speedway in Florida. The main goals for this release were to reduce the size of the system, increase the speed of the system, and, of course, to make it more reliable."
