Windows NT 4.0, released in 1996, was a significant step for the NT operating system, integrating the user interface from Windows 95 for improved usability. It also included Internet Explorer as a standard web browser and moved components into kernel-mode for better performance, though this also impacted security and reliability. Here's a more detailed look: Key Features and Improvements: Windows 95 Interface: The user interface from Windows 95 was incorporated into NT, making it easier to use than previous versions of NT. Internet Explorer: Internet Explorer was bundled with NT 4.0, providing a web browser out of the box. Performance Improvements: Moving components into kernel-mode led to improved performance, though it also introduced some security and reliability trade-offs. New Features: The server edition of Windows NT 4.0 included features like Internet Information Services 2.0, Microsoft FrontPage 1.1, Remote Access Service (including PPTP server for VPN functionality), and Multi-Protocol Routing service. Microsoft Cluster Server: The Enterprise edition of NT 4.0 introduced Microsoft Cluster Server. Support for Modern Hardware: Despite its age, Windows NT 4.0 can be installed on modern hardware, even CPUs like Ryzen 9. Hardware Requirements: x86 Version: Required at least a 486 processor, 16 MB of RAM, and 110 MB of hard drive space (variable depending on installed components). Dropped 80386 Support: Windows NT 4.0 dropped support for 80386 processors. Installation: Allowed installation without a floppy drive via CD-ROM media, but a floppy drive was needed for making an Emergency Repair Disk or if not booting directly from the CD. Legacy Status: Windows NT 4.0 is no longer supported by Microsoft. It is considered a legacy operating system, with its official end-of-life reached in 2004. However, it is still used by some individuals and companies for specific needs, particularly in legacy system. Build RTM Rerelease - August 24, 2000 End of Life - November 31, 2013
