Windows NTs first GUI was strongly influenced by (and programmatically compatible with) that from Windows 3.1; Windows NT 4s interface was redesigned to match that of the brand new Windows 95, moving from the Program Manager to the Windows shell design.Apr 17, 2018 If you have already installed Windows NT 4.0 Service Pack 6, you can update your computer to Service Pack 6a by installing the SP6a hotfix.
The following files are available for download from the Microsoft Download Center. Sporting the same face as its consumer counterpart Windows 3.1, it was completely different under the hood. A true 32-bit native operating system, Windows NT descended from the work Microsoft did while collaborating with IBM on OS2 after the great split, and bringing in former DEC. It is a processor-independent, multiprocessing and multi-user operating system. The first version of Windows NT was Windows NT 3.1 and was produced for workstations and server computers. It was intended to complement consumer versions of Windows that were based on MS-DOS (including Windows 1.0 through Windows 3.1x). Gradually, the Windows NT family was expanded into Microsofts general-purpose operating system product line for all personal computers, deprecating the Windows 9x family. NT formerly expanded to New Technology but no longer carries any specific meaning. Starting with Windows 2000, 2 NT was removed from the product name and is only included in the product version string. NT was the first purely 32-bit version of Windows, whereas its consumer-oriented counterparts, Windows 3.1x and Windows 9x, were 16-bit32-bit hybrids. Initially, it supported several instruction set architectures, including IA-32, MIPS, and DEC Alpha; support for PowerPC, Itanium, x64, and ARM were added later. The latest versions support x86 (more specifically IA-32 and x64) and ARM.

Major features edit A main design goal of NT was hardware and software portability. Various versions of NT family operating systems have been released for a variety of processor architectures, initially IA-32, MIPS, and DEC Alpha, with PowerPC, Itanium, x86-64 and ARM supported in later releases. Nt6 Fast Er Code Base WithThe idea was to have a common code base with a custom Hardware Abstraction Layer (HAL) for each platform. However, support for MIPS, Alpha, and PowerPC was later dropped in Windows 2000. ![]() Partial MS-DOS compatibility was achieved via an integrated DOS Virtual Machine although this feature is being phased out in the x86-64 architecture. NT supported per-object (file, function, and role) access control lists allowing a rich set of security permissions to be applied to systems and services. NT supported Windows network protocols, inheriting the previous OS2 LAN Manager networking, as well as TCPIP networking (for which Microsoft would implement a TCPIP stack derived at first from a STREAMS-based stack from Spider Systems, then later rewritten in-house). Windows NT 3.1 was the first version of Windows to use 32-bit flat virtual memory addressing on 32-bit processors. Its companion product, Windows 3.1, used segmented addressing and switches from 16-bit to 32-bit addressing in pages. Windows NT 3.1 featured a core kernel providing a system API, running in supervisor mode (ring 0 in x86; referred to in Windows NT as kernel mode on all platforms), and a set of user-space environments with their own APIs which included the new Win32 environment, an OS2 1.3 text-mode environment and a POSIX environment. Nt6 Fast Er Full Preemptive MultitaskingThe full preemptive multitasking kernel could interrupt running tasks to schedule other tasks, without relying on user programs to voluntarily give up control of the CPU, as in Windows 3.1 Windows applications (although MS-DOS applications were preemptively multitasked in Windows starting with Windows386). Notably, in Windows NT 3.x, several IO driver subsystems, such as video and printing, were user-mode subsystems. In Windows NT 4, the video, server, and printer spooler subsystems were moved into kernel mode.
