Windows NT 3. Windows NT, however, was a complete, bit operating system that retained a desktop environment familiar to Windows 3. By extending the Windows brand and beginning Windows NT at version 3. For several reasons, including the market success of Windows 3. When these premiered, their sales were limited by high system requirements , and a general lack of bit applications to take advantage of the OS’s data processing capabilities.

The origins of Windows NT date back to The OS was to be designed so it could be ported to different processor platforms, and support multiprocessor systems, which few operating systems did at that time. Both Microsoft and IBM wanted to market an operating system that appealed to corporate ” enterprise software ” customers. That meant greater security , reliability , processing power, and computer networking features.

To this end, Microsoft began by developing and testing their new operating system for a non- x86 processor: an emulated version of the Intel i The development team originally estimated that development would be complete within 18 months. However, the development team later determined that the i was unsuitable for the project.

In May , Microsoft released Windows 3. Windows 3. Win32 maintained the familiar structure of the bit APIs used by Windows, which would allow developers to easily adapt their software for the new platform while maintaining a level of compatibility with existing software for Windows. In an effort to ensure software taking advantage of Windows NT was available upon its release scheduled for late , Microsoft also distributed a bit software development kit to selected developers in attendance.

Due to the high cost of RAM at the time, critics thought that its high system requirements could affect the sales and adoption of Windows NT. Steps were taken to reduce its memory usage through methods such as paging. Although its stability and performance had improved, there were still fears that the OS could be released in an unfinished state or delayed further into During the product’s lifecycle, Microsoft published three service packs : Service Pack 1 was released on October 8, ; Service Pack 2 followed on January 24, ; and Service Pack 3’s release date was October 29, Microsoft terminated support for the operating system on December 31, Support for Windows NT 3.

Service Pack 1 support ended on April 24, , and finally, Service Pack 2 support ended on January 29, , only 1 year after general availability. The version for workstations, but not Windows NT 3.

Cutler set three main goals for Windows NT. The first goal was portability: in contrast to previous operating systems, which were strongly tied to one architecture, Windows NT should be able to operate on multiple architectures.

These parts were isolated so that they could easily be rewritten when porting the operating system to a new architecture. The second goal was reliability : The system should no longer crash due to a faulty application or faulty hardware.

This principle was applied to Windows NT. Despite all these goals, the performance of the operating system was optimized where possible, by adapting critical sections of the code to fast execution speed. To improve networking performance, large parts of the networking system were moved to the operating system core.

Windows NT was designed as a networking operating system. In this branch, Novell had a lead with its product NetWare , mostly because of a lack of competition, and Microsoft failed to develop a product which could challenge NetWare’s lead. Cutler hoped to gain additional customers with a reliable networking operating system.

Therefore, Windows NT was positioned as a high-end operating system in an interview with the product manager David Thacher. It was not designed to replace Windows 3. While Windows NT 3.

The operating system is not DOS-based, but an independent bit operating system; many concepts were taken from Cutler’s previous operating system, VMS. Positioned above the operating system core are the subsystems. There are two types of subsystems: one are the integral subsystems , which perform important operating system functions.

One such subsystem is the security subsystem, which handles the logon process and monitors the security of the system. The other type of subsystem is the environment subsystem , which exposes the operating system functions to applications via application programming interfaces. Windows NT applications can only run on one platform, and must be recompiled for every platform. The bit subsystem also contains all output functions, including the Graphics Device Interface GDI , [33] so all other subsystems have to call the bit subsystem to be able to output text or graphics.

It manages applications originally built for DOS. Built on top is Windows on Windows WoW , which allows applications built for bit Windows operating systems like Windows 3. A faulty bit Windows application is in this way able to cause all other bit Windows applications but not Windows NT itself to crash.

It allows a multiboot setup of multiple instances of Windows NT 3. Every user has to log on to the computer after Windows NT 3. All users have their own user account , and user-specific settings like the Program Manager groups are stored separately for every user. Users can be assigned specific rights, like the right to change the system time or the right to shut down the computer.

To facilitate management of user accounts, it is also possible to group multiple user accounts and assign rights to groups of users. This was added in Windows NT 3. Designed as a networking operating system, Windows NT 3. When a network printer is installed, the required drivers are automatically transferred over the network, removing the need to manually install the drivers for every computer.

While the workstation allows one RAS connection at a time, the server supports This facilitates localization of the operating system. The previous code pages are still supported for compatibility purposes. The Windows registry , introduced with Windows NT 3. The Advanced Server is designed to manage the workstation computers. This way, a user can log on from any computer in the network, and users can be managed centrally on the server. Trust relationships can be built to other domains to be able to exchange data cross-domain.

The Advanced Server contained further, server-specific administration tools. Because Windows NT 3. The PCI bus , however, is expressly not supported. Minimum system requirements on x86 systems include a 25 MHz processor, at least 12 megabytes of memory, 75 megabytes of hard drive space, and a VGA graphics card.

On RISC systems, megabytes of hard drive space is needed. Due to an error in the processor detection routine, Windows NT 3. Microsoft never fixed the problem, but unofficial patches are available. Estimates in November counted only Windows NT applications. However, not all reception was negative; the multitasking capabilities of the operating system were rated positively, especially compared to Windows 3.

Even though the operating system’s actual success was only moderate, it had a huge lasting impact. Developers of Unix derivations for the first time strived to standardize their operating systems, and Novell was so concerned about its market share that it bought a Unix vendor.
