On July 31, 1996, Microsoft released Windows NT 4.0, codenamed Cairo, which integrated the Windows 95 interface into a 32-bit enterprise operating system. It was the last version to support multiple CPU architectures, including Alpha, MIPS, and PowerPC. Windows NT 4.0 included features such as the Start Menu, Taskbar, Task Manager, and support for advanced functionalities like the cryptography API and DirectX (v2). The minimum hardware requirements were a CPU of 33 MHz or better, 32MB of RAM, SVGA graphics, and a 256 MB hard disk. Following its launch, Microsoft introduced versions for embedded systems and a Terminal Server edition. The release of Windows XP in 2001 marked a shift away from DOS-based consumer operating systems.
