Windows 98 build 1351 is a Developer Release build of Windows 98, and also the earliest available build of the operating system. It was originally shared on 30 December 1996 by warez scene group PWA. Hours later warez scene group GLoW released their own copy of the build, and described it as "the December release [...] it [wasn't] Beta 1 because IE 4 [wasn't] ready". It was included on the warez CD Dragon 5, with claims of performance improvements from various sources including the warez CD author, citing that "it's much faster".[1]

Setup[edit | edit source]

The setup of this build has gained a massive visual redesign. It no longer has aspects of dark blue, instead it uses gray and teal as colors when the color depth is set to 4-bit (16 colors) and white and gray when set to 8-bit (256 colors) or higher.

A sidebar has been added to setup, showing the steps of setup. In this build, it only has basic functionality, as later builds introduce more steps, a time indicator, as well the Microsoft logo at the bottom of the sidebar.

Setup also makes usage of new billboards during the file copy phase. The images use teal as background as well as black for the symbols. The text has been changed to tell the user about the improvements of Memphis compared to Windows 95.

The creation of a startup disk can no longer be canceled before setup begins to prepare the files for the disk. It can only be canceled when the user is prompted to insert a floppy disk. The startup disk is now created during "Collecting Information" and no longer between "Collecting Information" and "Copying Files". After file copy is complete, setup immediately restarts the system.

During restart, the first boot screen is identical to Windows 95, except that the Windows 95 reference has been changed to mention Memphis. The Memphis text however is notably stretched out to fill in the text. The default boot screen has been changed from the clouds in the background featuring a Windows logo with shadows as seen in Windows 95 to the clouds inside of an ellipse (keyhole effect) and a Windows logo without shadows, the wording "Developer Release" in a serif font and the Memphis branding.

Changes[edit | edit source]

  • Microsoft Plus! theming components such as 256 color icons are now installed by default.
  • A desktop watermark was included for the first time outside Checked/Debug builds.
  • Starting with this build, boot disks created in setup or later from the Add/Remove Programs Control Panel applet now include a CD-ROM driver for IDE/ATAPI CD-ROM drives.
  • This build is the first to include the FAT32 Conversion Utility, which can convert FAT16 partitions on drives to FAT32. However, it is not listed in the Start menu.
  • This build includes a Start menu option called "Internet System Update", which will ultimately become Windows Update. It tries to connect to a website at winbeta.microsoft.com, which is no longer possible nowadays due to the servers having been taken down many years ago.
  • There is also a bug reporting tool, which also tries to access a web service at winbeta.microsoft.com.
  • COMMAND.COM has been updated to read "Microsoft(R) Memphis" and to have a copyright date of 1981-1997 instead of 1981–1996 in Windows 95 OSR2, despite being compiled in December 1996.
  • WordPad has been updated to version 2.0 using Microsoft Foundation Classes version 4.0.
  • WELCOME.EXE has been redesigned to replace Windows 95 references with Memphis. Links to the Windows Tour and "What's New" as well as Online Registration were removed.
  • An Alpha 2-era build of Internet Explorer 4, build 1158 (from 10 August 1996, 10 days before the dumped build 1169), is included. IE4 shell integration is not included (Windows Explorer is from Windows 95 RTM, COMDLG32.DLL is from a hotfix and SHELL32.DLL is from OSR2). SHDOCVW.DLL detects the lack of updated shell (by checking if SHELL32 exports DllGetVersion) and because of this claims to be IE3 in the about window.
  • A very early build of DirectX 5.0 is included.
  • Microsoft NetMeeting 1.0 is included.
  • Native DVD support has been added due to the addition of support for the UDF file system.
  • Support for dual monitors has been added.

Menu animations[edit | edit source]

Though this build includes the sliding menu animations seen in Windows Nashville build 999, they are disabled by default. To enable them, a string has to be added to the registry:

[HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics]
"MinAnimate"="1"

Bugs and quirks[edit | edit source]

Installation[edit | edit source]

  • Files for accessing Novell NetWare services are missing.
  • When printing a test page, setup will prompt for the CD-ROM drive but will not detect it; select to copy files from C:\WINDOWS\SYSTEM\PRECOPY.

Network Setup[edit | edit source]

This build allows the user to specify the network setup during the initial phase of setup before copying files. If this occurs, the network adapters will be duplicated after the hardware detection phase.

System crash during second stage of setup[edit | edit source]

Sometimes, setup crashes with a blue screen of death when configuring Windows Help or before setting up hardware. If this occurs, restart the computer to continue the installation.

ACPI[edit | edit source]

ACPI support is in very early development and crashes easily. ACPI must be disabled or setup will crash with a red screen of death during the hardware portion (used in early builds for ACPI errors).

Sounds[edit | edit source]

This build does not have a boot sound set by default. Trying to set it leads to an error which claims that the sound file is missing, however, it is still present in C:\Windows\Media. This bug persists until build 1400.

Infrared[edit | edit source]

Just like in Windows Nashville build 999, Infrared support can be uninstalled from "Add/Remove Programs", which also removes the Infrared Control Panel applet.

File differences[edit | edit source]

The following files have been introduced or removed compared to the RTM build of Windows 95 OSR2:
