  3. 3. Windows NT 3.5 is the second release of the  Microsoft   Windows NT   operating system . It was released on September 21, 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 &quot;Daytona&quot; 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 .
  4. 4. <ul><li>New features in Windows NT 3.5 include the 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. </li></ul><ul><li>In July 1995, Windows NT 3.5 with Service Pack 3 was rated by the  National Security Agency as complying with  TCSEC  C2 criteria. </li></ul><ul><li>Windows NT 3.5 refuses to install on a processor newer than the original  Pentium  (P5 core). [3] Windows NT 3.51  fixed this. It is however possible to modify files on the install CD which will allow it to install. </li></ul>
  5. 5. <ul><li>Windows NT 3.51  is the third release of  Microsoft 's  Windows NT  line of  operating systems . It was released on  May 30 ,  1995 , nine months after  Windows NT 3.5 . The release provided two notable feature improvements; firstly NT 3.51 was the first of a short-lived outing of  Microsoft Windows  on the  PowerPC   CPU  architecture. The second most significant enhancement offered through the release was that it provides client /server  support for interoperating with  Windows 95 , which was released three months after NT 3.51.  Windows NT 4.0  became its successor a year later; Microsoft continued to support 3.51 until  December 31 ,  2001 . </li></ul>Windows NT 3.51
  6. 6. Overview <ul><li>The release of Windows NT 3.51 was dubbed &quot;the PowerPC release&quot; at Microsoft. The original intention was to release a PowerPC edition of NT 3.5, but according to Microsoft's David Thompson, &quot;we basically sat around for 9 months fixing bugs while we waited for IBM to finish the Power PC hardware&quot;. Editions of NT 3.51 were also released for  Intel 's  x86 ,  MIPS , and  DEC Alpha  architectures. </li></ul>
  7. 7. <ul><li>Despite the significant difference in the kernel base, Windows NT 3.51 is readily able to run a large number of  Win32  applications designed for  Windows 95 . Most recent 32-bit applications will not work as the developers have prevented their application from working with any Windows version earlier than Windows 98, also because some applications do not work properly with the older Windows NT 3.51 interface. Despite this, Microsoft in their application releases muddied the issue, releasing  32-bit  versions of  Microsoft Office  right up to Office 97 SR2b, but relying upon  16-bit  versions of  Internet Explorer  technology. This is probably because 32-bit versions of  Internet Explorer 4.0 and later integrated with the Windows 95 desktop, and NT 3.51 still used the Windows 3.1 desktop. Later on, up to  IE 5.0 , but not later 5.x versions, were offered. </li></ul>
  8. 8. <ul><li>Microsoft also released test versions of a shell refresh, named the  Shell Technology Preview , and often referred to informally as &quot;NewShell&quot;. The update was designed to replace the Windows 3.x Program Manager/File Manager based shell with a  Windows Explorer -based  graphical user interface . The release provided capabilities quite similar to that of the Windows &quot;Chicago&quot; ( codename  for Windows 95) shell during its late beta phases, however was intended to be nothing more than a test release. There were two public releases of the Shell Technology Preview, made available to  MSDN  and  CompuServe  users;  May 26 ,  1995  and  August 8 ,  1995 . Both held Windows Explorer builds of 3.51.1053.1. The Shell Technology Preview program never saw a final release under NT 3.51. The entire program was moved across to the  Cairo  development group who finally integrated the new shell design into the NT code with the release of NT 4.0 in July 1996. </li></ul>
  9. 9. <ul><li>Five  Service Packs  were released for NT 3.51, which introduced both bug fixes and new features. Service Pack 5, for example, fixed issues related to the  Year 2000 problem . </li></ul><ul><li>NT 3.51 was the last of the series to run on a  Intel 80386  processor. This, its ability to use  HPFS  partitions (which Windows 2000 and later could not), and its ability to run at least some of the common control API, means that it still finds a place for occasional use on older machines. </li></ul>
