Windows NT 3.1 build 404

Windows NT 3.1 build 404 is the March 1993 beta of Windows NT 3.1, which was only available in the Workstation edition for many years, until an Advanced Server version of this build was later found and shared on 26 March 2021 on BetaArchive.https://www.betaarchive.com/forum/viewtopic.php?t=42430
== NFO files ==
The following NFO files were included as part of the WILD and [unknown] releases.
==Changes==
*Changed the setup to resemble the RTM build.
*Added some new applications like Mail and Schedule+ which are inherited from Windows for Workgroups 3.1.
*Changed the default color scheme to match the one used in Windows 3.1 instead of the version used in Windows 3.0.
* This is the first build of Windows NT to launch NTDETECT.COM to check for hardware. It bears the version number 1.0.
*This build updates the copyright date in certain About boxes from 1985–1992 to 1985–1993.
*The copyright date in the winnt bitmap is updated from 1992 to 1992, 1993.
*The S3 display driver has been updated to now also support the 86c8xx line of adapters and the 86c928 adapter. It does, however, not work with the 86x, 96x and Trio32/64 lines of adapters.
* Cirrus Logic, Number 9 GXE, XGA-2, Western Digital/Paradise and Trident display drivers have been added.
*This build adds support for Adaptec AHA-151x/152x, AIC 6260/6230, Trantor T128/T130b and BusLogic SCSI host adapters.
* "Disk Manager" has been renamed to "Disk Administrator".

Windows NT 3.1 build 436

Windows NT 3.1 build 436 is a build of Windows NT 3.1, mentioned in the file WINSCNF.C from the Windows NT 4.0 source code.
// NOTE NOTE NOTE: Build 436. If we attempt to close a key that has been

Windows NT 3.1 build 438

Windows NT 3.1 build 438 is the April 1993 beta of Windows NT 3.1. It is not much different from the previous build, which was released a month earlier. A version of the build in the Alpha AXP architecture was shared on 4 August 2020.
This build was mentioned in an internal Microsoft e-mail from August 1993http://antitrust.slated.org/www.iowaconsumercase.org/011607/7000/PX07689.pdf where it states that it was delivered to Novell in order to test their NetWare Client for the then-upcoming NT operating system, highlighting the issue that further recompilations of the aforementioned software had failed to work properly. The e-mail also states that Novell had received the June 1993 beta three weeks later than what was originally promised by Microsoft.
== NFO file ==
== New features and changes ==
* The Control Panel and Windows NT Setup icons are now updated to match the ones in Windows 3.1.
* NTLDR has been updated to version 3.1 as seen in the RTM and it no longer shows a list of loaded drivers unless the user adds the /SOS switch to BOOT.INI.
* When changing the display type in Setup, a warning message will appear, as selecting a display type incompatible with the current installed one will make Windows NT unusable, necessitating reinstallation. Setup recommends to select the proper display type after Windows NT has been fully installed, as the user still has access to the Last Known Good Configuration to recover the previous hardware state.
*ATi, generic VESA 800x600 and S3 1280x1024 display drivers have been added.
*Most of the bugcheck messages have been renamed to their modern names, being in all caps and spaced with an underscore. When a bugcheck also occurs, it will now print addresses of several drivers before the crash occurred. Alongside, a new bugcheck code has been added.https://www.geoffchappell.com/studies/windows/km/bugchecks/index.htm
** INACCESSIBLE_BOOT_DEVICE (0x7B)
*** In addition, this build adds a set of instructions to the end of each bugcheck, stating "Restart your computer. If this message reappears, do not restart. Contact your system administrator or technical support group, and/or peripheral device vendor." This is actually a STOP error itself, being 0x7C (BUGCODE_PSS_MESSAGE), but it is invoked every time the bugcheck finishes printing details of the crash. It was removed during Windows Server 2003's development, where it was then replaced with a valid STOP error, BUGCODE_NDIS_DRIVER.

Windows NT 3.1 build 475

Windows NT 3.1 build 475 is the June 1993 beta of Windows NT 3.1. It was uploaded to BetaArchive on 25 February 2017.https://www.betaarchive.com/forum/viewtopic.php?t=36735 Prior to its upload, it was mentioned in an internal Microsoft e-mail from August 1993http://antitrust.slated.org/www.iowaconsumercase.org/011607/7000/PX07689.pdf where it states that the build was delivered to Novell in June 1993 in order to test their NetWare Client for the then-upcoming NT operating system; the e-mail also states that Novell had received the April 1993 beta sometime earlier.
This build refers to itself in the boot screen and Winver as build 4755, and as build 475 on the default desktop wallpaper. It's possible that 4755 was intended to be 475.5. A similar observation can be found within the final build, 3.10.511.1, where the kernel's file version is 3.10.5098.1, perhaps meant to be 3.10.509.8.
On 5 April 2020, ReflectiaX shared a picture of the CD containing the Advanced Server version of this build.
== NFO file ==
== New features and changes ==
* It is the first known build to use 50 lines text mode for the text mode display during boot and the blue screen of death.
* The copyright date on the winnt bitmap has been changed from 1992, 1993 to 1985-1993.
* When booting this build, a message will appear for a short time to press to load the Last Known Good Configuration/Hardware Profile menu.
* The "door" icon on the safe to shutdown screen has now been changed to a "nighttime window" icon, which would be used in subsequent Windows NT builds.
*New bugcheck codes have been added, and the fatal system trap errors have been removed, with them leading to a new bugcheck, 0x7F.https://www.geoffchappell.com/studies/windows/km/bugchecks/index.htm
** INSTALL_MORE_MEMORY (0x7D)
** UNEXPECTED_KERNEL_MODE_TRAP (0x7F)
** Hardware malfunction. (0x80, later renamed NMI_HARDWARE_FAILURE)
** SPIN_LOCK_INIT_FAILURE (0x81)
*** In addition, the boot screen message now prints itself as a message stored in the bugcheck message table, being at value 0x4000007E. It is referred to in documentation as WINDOWS_NT_BANNER, although it can be called by the stop code 0x7E. It was reworked during Windows XP's development into SYSTEM_THREAD_EXCEPTION_NOT_HANDLED, as the no-GUI boot screen prints nothing in that version.

Windows NT 3.1 build 511

Windows NT 3.1 build 511 is the original RTM build of Windows NT 3.1, which was released on 27 July 1993.
== Changes from build 475 ==
During the file copy stage in the graphical part of setup, the dialog with the progress bar has been moved to the lower-right corner. In the upper-left corner, there are now billboards showing the features and advantages of Windows NT as well as a reminder to register at Microsoft.
=== OS Loader ===
* The message during boot to press the to initialize the Last Known Good Configuration/Hardware Profile menu has been altered.
* The menu entry to load a previous installed system from the C drive has been removed, letting Windows NT directly boot.
* Changed the message of the boot screen (WINDOWS_NT_BANNER or 0x4000007E) to "Microsoft (R) Windows NT (TM) Version 3.1", now only reporting the system memory without the build number.
== Bugs ==
=== Processor check ===
Setup doesn't detect processors newer than the original Pentium, as well as some models of 386, 486, and Pentium processors. To bypass this, two INF files must be edited after the first stage (in text mode) of setup is done. Change the line STF_PROCESSOR = "" ? $(!LIBHANDLE) GetProcessor to STF_PROCESSOR = $(ProcessorID_I586) in INITIAL.INF and SETUP.INF files in the SYSTEM32 subdirectory of the target installation directory. If you're doing this on a 386 processor use I386, and for 486 processor use I486 instead of I586.

Windows NT 3.1 build 528

Windows NT 3.1 build 528 is the second RTM build of Windows NT 3.1, released two months after the original RTM (build 511). It introduced support for the Alpha architecture and included the first set of bugfixes for build 511, which were also released separately in the form of a service pack. Later service packs, namely SP2 and SP3, kept the same build number.
== Compaq OEM version ==
There is also a Compaq OEM version of this build dated to January 1994 which was dumped by Internet Archive user nt351 on 15 April 2019.https://archive.org/details/yarmulka_geocities_Nt31 
It contains a modified setup boot disk image (called BOOT350.IMG in relation to it being a 1.44MB image for a 3.5" floppy disk) and some additional files, and is an all-in-one disc containing both client and server builds in the German, English, French and Spanish languages. The modified setup boot disk allows the user for choosing the language and SKU. 
However, all registry hives on the CD are encrypted and a Compaq License Diskette containing an encrypted decryption key is required to install. The key encryption key is a floppy-specific product key that is requested after reading the Compaq License Diskette by SETUPAPP. So far, no image of this floppy has been dumped, making it impossible to install this OEM version.

Windows NT 3.51 build 1057.1 (Japanese Release Candidate)

Windows NT 3.51 build 1057.1 (Japanese Release Candidate) is a pre-release localization build of Windows NT 3.51, which was uploaded to the Chinese website BetaWorld on 17 February 2022.https://www.betaworld.cn/Windows_NT_3.51:3.51.1057.1_(Japanese_Release_Candidate) It was later shared on 28 October 2024.
Unlike other international builds at the time, the timebomb in this build works properly and does not allow login after expiration.
The timebomb is implemented in winlogon.exe. There is an additional check to prevent a user from setting the date back after the timebomb has expired; before the date check it will check for a registry entry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon!BetaExpire (REG_DWORD) - if this value is set to 1 (which is done before showing the expiry message box) then the timebomb will always be considered as expired.
