== New features and changes ==
* Like build 1515, most NT 4.0 references have been replaced with NT 5.0. However, many parts of the interface are still very similar to NT 4.0.

* Replaced many icons with the ones from Windows 98.
* Advanced logon options now allow the user to login using Kerberos2.
* The new hardware found dialog has been slightly updated, with the addition of a Cancel button. The UI for selecting a driver also got revamped, with the user now being thrown directly into the Found New Hardware wizard.
* The wizard to share folders and files over the network is now installed by default, and is attached to the user interface. To access it, right click inside a folder.
* A new fade in effect has been added to Task Manager. The fade in effect is used as a window opening animation on supported video cards.
* Windows Installer (then known as Microsoft Install Server) now launches an error (with code 1617) instead of qutting directly if launched without a parameter specified.
* Microsoft Personal Fax is now installed by default, but without being attached to the user interface yet. It can be launched by running fax.hlp faxsend faxcover faxcfgst.
*The Automated System Recovery feature has been implemented into NTBackup as "Disaster Backup Recovery". Initially planned to be included into the final release of Windows 2000, it was later removed in build 2031 and then re-added in Windows XP build 2210.
* The following HALs have been removed:
** AST Manhattan SMP (HALAST.DLL)

=== Setup features ===
* This build introduces a newly revamped setup wizard based on the Wizard 97 design. In addition, it is now able to upgrade from Windows 95, though only the RTM and OSR1 are confirmed for a successful upgrade, since OSR2 has not been tested yet. Therefore, a warning message will appear when selecting the upgrade option in setup when using 95 OSR2. To upgrade successfully from Windows 95 to this build, make sure that:
** hardware supported by NT is used
** NetMeeting is not installed
** Internet Explorer 4 and later is not installed
* Registry hives are now generated from information files instead of being pre-made.
* The graphical stage of setup now uses 256 colors instead of 16 colors if the video adapter is supported and supports such a setting.
* A debug text has been added to the text-mode stage while loading files.

== Bugs and quirks ==
=== Installation ===
* When installing from DOS or Windows 95 using either WINNT.EXE or WINNT32.EXE and not booting from the CD, the OS Loader has a bug during setup that it tries to load NTLDR, but since $LDR$ installs instead, it will be stuck on the OS Loader in an infinite loop. Editing the boot sector file (BOOTSECT.DAT) to boot from $LDR$ will allow setup to continue. This can be done using any MS-DOS boot disk with EDIT.COM or by booting the existing DOS/Windows 95 in command-line only mode. At the prompt, type edit /80 C:\$WIN_NT$.~BT\BOOTSECT.DAT and change the first NTLDR in the file to $LDR$. Save the file, remove the disk, restart and the installation should continue as usual.
*When upgrading from Windows NT 4.0 or build 1515 with WINNT32.EXE, during the text mode setup it will request for the Windows NT 4.0 CD, and then when the Windows NT 4.0 CD is inserted, the setup instantly crashes with IRQL_NOT_LESS_OR_EQUAL. To upgrade seamlessly, check the "Copy files from CD-ROM to the hard drive" option in "Advanced Options".
*When creating bootable floppy disks for setup, it should be noted that the setup disk #1 no longer fits onto a standard high-density 1.44 MB diskette. It is recommended to use a DMF-formatted or a 2.88 MB diskette instead for that (the latter given that the floppy disk drive supports such diskettes).
* Due to ActiveMovie being included in this build, the Windows NT EULA has been overwritten with the ActiveMovie one.
=== Windows Explorer ===
* Windows Explorer doesn't have a very good graphics rendering engine as there is a graphical bug where anything dragged over Explorer windows will remain on the background of the Explorer window. This does not affect folders with custom background. Disabling Web View (by setting to "Display standard appearance" in the View tab in Options dialog from View menu) fixes this problem.
* Most Accessories shortcuts are gone in this build, although most applications are still present and can be launched using the Run command.
