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.https://web.archive.org/web/20160504133721/http://www.osbetaarchive.net/topic/486-leak-windows-nt-401130-workstation
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".
* 386-based systems are no longer supported. A CPU check for a 486 or greater processor has been implemented in WINNT.EXE (there is no WINNT32.EXE on this build's CD), and attempting to boot this or later builds with a 386 processor results in a crash.
* Updated the 16-bit variant of Dr. Watson from version 0.80 to 1.00b.
* The default installation directory is now C:\WINNT instead of C:\WINNT35.
*This is the earliest available build to move integral User and GDI code to a kernel mode driver (WIN32K.SYS) in order to increase system reliability.
* Six system calls (NtCreateChannel, NtListenChannel, NtOpenChannel, NtReplyWaitSendChannel, NtSendWaitReplyChannel, NtSetContextChannel) were added for a new "very high speed local inter-process communication mechanism" (as described in private\ntos\ke\channel.c in the leaked NT 4 source code). In a later build, sometime prior to the RTM, the implementations were removed and replaced with stubs returning STATUS_NOT_IMPLEMENTED (the leaked NT 4 source code shows the implementations ifdef'd out); the entire set of syscalls were removed at some point during Windows XP development.
*WINNT256.BMP was poorly edited to change the Version from 3.51 to 4.0. WINNT.BMP however, stays the same, at 3.51.
* Serveral Object File System components are included in the build, including the driver itself, OFS.SYS.
** Additionally, text setup (when configured as being for Cairo), can format partitions directly as OFS, using AUTOFMT.EXE (which, at this time, was a Cairo-only component). It can also handle formatting FAT and NTFS partitions (and in fact the exact same code was reintroduced in Windows 2000, sans OFS, to support direct NTFS formatting), but the function is only called for OFS.
*New bugcheck codes have been added.https://www.geoffchappell.com/studies/windows/km/bugchecks/index.htm
** UP_DRIVER_ON_MP_SYSTEM (0x92)
** INVALID_KERNEL_HANDLE (0x93)
** KERNEL_STACK_LOCKED_AT_EXIT (0x94)
** PNP_INTERNAL_ERROR (0x95)
** INVALID_WORK_QUEUE_ITEM (0x96)
*** Additionally, code 0x5D, which was originally HEAP_INITIALIZATION_FAILED before its removal in build 1024, has been added back with a reassigned name of UNSUPPORTED_PROCESSOR.https://www.geoffchappell.com/studies/windows/km/bugchecks/5d.htm This reassigned bugcheck is intended to halt a system that was running any 386 processor while giving a more descriptive error, as earlier versions simply reported a more vague HAL_INITIALIZATION_FAILED (0x5C) bugcheck for early unsupported 386 processors. When a 386 processor is detected, the system immediately crashes with only a first parameter of 0x00000386.
===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 (APPWIZ.CPL).
*The Desktop applet (DESK.CPL) 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" prompt of Windows 95, it also does not have 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 security options interface has not been updated and still refers the Task List.
* Paintbrush has been replaced by Paint.
==Bugs and quirks== 
*Pressing the button while testing higher display resolutions causes a bugcheck with error code 0x0000001E (KMODE_EXCEPTION_NOT_HANDLED) caused by win32k.sys.
* Setting bitmaps as backgrounds doesn't work via the Display applet. It works properly in the Desktop applet.
*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.
*The included S3 graphics driver has problems with displaying red, yellow and gray colors on the Trio32/64, Vision868 and 968 adapters. Predating adapters, such as the 86c928, are not affected.
