New features and changes[edit | edit source]

Branding wallpapers[edit | edit source]

The Server edition of this build uses the lanmannt and lanma256 backgrounds from the RTM, but the Workstation edition uses a slightly different one:

  • A small "Version: 4.0" text is in place of "4.0" next to "Workstation"
  • The Windows logo has a trademark symbol (™) along with a drop shadow in addition to a glow effect. Only the latter is present in the final version.
  • The text "with Microsoft Internet Explorer" beneath "Workstation" is absent.
  • The registered trademark symbol (®) next to the Microsoft logo is barely visible compared to the final version.
  • Copyright notices are written in Arial font instead of Franklin Gothic.
  • Colors (particularly the Windows logo and upper part of the background) are slightly darker.

Further changes[edit | edit source]

  • This is the first build where AUTORUN.EXE launches when the installation disc is inserted. It is similar to what seen in Windows 95. However, "Hover!" and other extras are not included.
  • This build identifies itself as "RC 1.3".
  • The colors used for the end-user license agreement have been inverted, with blue being used for the background and gray for the text.
  • New message entries were added to the bugcheck message table for the boot screen to correct a grammatical error for multiprocessor systems and to add an RC tag for beta Service Pack releases:[1]
    • 0x4000009D (WINDOWS_NT_INFO_STRING_PLURAL) is a copy of the 0x40000088 (WINDOWS_NT_INFO_STRING) message, with the only difference being changing the "System Processor" text to "System Processors". This string is normally used only if a multiprocessor HAL has been installed.
    • 0x4000009E (WINDOWS_NT_RC_STRING) is the "RC" string that displays if a prerelease version of a Service Pack has been installed.
