The Windows NT name denotes major technology advancements that it introduced to the Windows product line including eliminating the 16-bit memory access limitations of earlier Windows releases. Each Windows release that includes its technology is considered to be based on, if not a revision of, Windows NT even though the Windows NT name has not been used since 1996.
Windows NT provides many features including:
- pure 32-bit memory access — earlier, consumer-oriented versions, Windows 3.1x and Windows 9x, were 16-bit/32-bit hybrids
- Multi-architecture support — initially instruction set architectures including IA-32, MIPS, and DEC Alpha; support for PowerPC, Itanium, x64, and ARM were added later and later still: x86 (including IA-32 and x64) and ARM
- Many system services including: Windows shell, Windows API, Native API, Active Directory, Group Policy, Hardware Abstraction Layer, NTFS, BitLocker, Windows Store, Windows Update, and Hyper-V
