the series to be compatible with the Intel 80386 processor. NewShell On May 26, 1995, Microsoft released a test version of a shell refresh, named the Shell Technology Preview, and often referred to informally as "NewShell". This was the first incarnation of the modern Windows GUI with the Taskbar and Start menu. It was designed to replace the Windows 3.x Program Manager/File Manager based shell with Windows Explorer-based graphical user interface. The release provided capabilities quite similar to that of the Windows "Chicago" (codename for Windows 95) shell during its late beta phases; however, it was intended to be nothing more than a test release. There was a second public release of the Shell Technology Preview, called Shell Technology Preview Update made available to MSDN and CompuServe users on August 8, 1995. Both releases held Windows Explorer builds of 3.51.1053.1. The preview program provided early feedback for the Shell Update Release, the next major Windows NT version with the new interface built-in, which was released in July 1996 as Windows NT 4.0. Updates Five Service Packs were released for NT 3.51, introducing both bug fixes and new features. Service Pack 5, for example, fixed issues related to the Year 2000 problem. Hardware requirements Supported EIDE addressing schemes include logical block addressing (LBA), ONTrack Disk Manager, EZDrive, and extended cylinder-head-sector (ECHS).
