Windows NT 4.0 build 1130

Windows NT 4.0 build 1130 is the earliest available build of Windows NT 4.0. This build comes with the Windows Explorer interface. The Workstation edition was listed on the Fate 008 warez CD, but was found in another warez source and shared on OSBetaArchive on 9 December 2015.

Being very early in development, it still contains many Windows NT 3.x apps and program groups on the Start menu, and is very similar to the Shell Technology Previews of Windows NT 3.51.

New features and changes

 * This build no longer loads the driver for HPFS partition access, and thus the user is no longer able to access HPFS-formatted partitions.
 * Removed the ability to install the system from 3½-inch floppy disks.
 * The default mouse pointer is set to "Animated Hourglass".
 * A CPU check for a 486 or greater processor has been implemented in  (there is no   on this build's CD), and as such the installer fails on 386-based systems.

Setup
Setup has been massively updated, featuring a new setup wizard. Network Configuration, Date/Time and Display Properties however were left untouched.

Control Panel

 * Introduced the "Add/Remove Programs" Control Panel applet.
 * The Desktop applet received major changes compared to the one from Windows NT 3.51. However, the preview bitmap still shows the legacy shell.
 * New regional settings, including an interactable world map.

Shell

 * This build's interface mostly resembles those of the Shell Technology Previews, including the Chicago-style window controls, though there are some differences.
 * The start menu has two program sections: one for user-wide and one for system-wide (or "Common") ones. This is unique to this build, as even the Shell Technology Previews behave like later builds, so there is only one program section with both types of program groups, separated by the suffix "(Common)" for the system-wide ones.

Applications

 * This is the first build to feature an early, primitive iteration of the Task Manager. It not only has a similar appearance to the earlier Task List and the "Close Program" feature of Windows 95, it also has not the ability to load programs unlike the former one and is not in sync if a new program launched, requiring the user to press the "Refresh" button. But it allows programs to cascade and tile themselves, which is not available in the final Task Manager. The entry in the Ctrl security options interface has not been updated and still refers the Task List.
 * This build also introduces Windows NT Diagnostics, again in a very primitive form.
 * Paintbrush has been replayed by Paint.

Bugs

 * Testing the 1024x768 screen resolution at true color can sometimes result in a bugcheck with error code  (or  ) caused by.
 * True color does not work with the S3 device driver, regardless of what adapter being used. It displays red as black, yellow as green and magenta as blue. True color has been confirmed to work with the Cirrus Logic driver.
 * The  folder on the installation media is not recognized by DOS. The solution is to use boot disks created by setup instead or to copy the   folder to the hard disk.
 * The Sound Blaster driver does not work, even with the right resources provided. Sound has been confirmed to work with the Windows Sound System.
 * Disk Administrator utilizes the STOP sign icon in the start menu instead of the actual one.
 * Many applications listed in the Start menu utilize their executable name instead of their full one.
