Despite its interface identical to Windows 95, Windows NT 4.0 is fundamentally different from it. While the first system created for home users combines a 32-bit programming interface with a 16-bit MS-DOS kernel, its counterpart from the "professional" NT line has a fully 32-bit architecture and is completely independent from DOS. NT 4.0 supports the vast majority of software written with 95 in mind, but many 3D games do not work under it due to limited DirectX support. NT 4.0 also has higher hardware requirements than 95. While for 95 recommendations the amount of memory is 8 MB, for NT 4.0 in Workstation edition it is already 32 MB. NT 4.0 is also less user-friendly than 95. It does not support Plug and Play and USB technology or the FAT32 file system introduced in OSR2 version 95 (although you can use third party drivers to get a replacement for these functions), nor does it have a Device Manager. The system was designed for business users and server administrators, as evidenced by the server editions of this system.
Windows NT 4.0 was released in five editions.
Server - released in 1996, designed for small businesses;
Server, Enterprise Edition - released in 1997, supporting eight-way symmetric processing and computer clusters;
Terminal Server - released in 1998, allowing users to log on remotely.
Workstation - designed for use in company workstations.
Embedded - used mainly in ATMs.
