Windows NT 4.0 is the successor to the Windows NT 3.x release. In this release, the user interface from Windows 95 was integrated, making NT just as easy to use as its consumer counterpart. Internet Explorer was bundled, providing a web browser out of the box. Speed was improved by moving components into kernel-mode, at the expense of security and reliability – changes Windows is suffering from today, and is being reverted. NT 4 was followed up by Windows 2000.
Supports IA-32, Alpha, MIPS, and IBM PowerPC. This was the first version of Windows to bring the Explorer desktop from Windows 95 to the Windows NT line. A preview of this technology was shown as NewShell, installable on top of Windows NT 3.51.
While Windows NT 4.0 sported the look of its consumer counterpart Windows 95 it did not feature Plug-and-Play or some other Chicago technologies.
