关于对话框

Windows 8 build 8400 is the official Release Preview and Release Candidate build of Windows 8, released to the general public on 31 May 2012.[1][2] The Simplified Chinese language variant was leaked across different Chinese forums two days ahead of the official debut.[3]

The ARMv7 compile of this build was showcased on a Channel 9 blog post titled Developing for Windows on ARM,[4] and was distributed to partners participating in the Ecosystem Engineering Access Program (EEAP).[5][6] Its components were additionally released in the form of a set of Repair Content Packages,[7] which are used by DISM /Cleanup-Image /RestoreHealth to repair an existing Windows installation.[8]

New features and changes

User interface

Only minor differences can be observed across the user interface when compared against the previous build: the bug preventing task previews from displaying within the Windows shell has been fixed, and the Desktop Window Manager client area in Windows Explorer no longer extends to the navigation bar when the Ribbon user interface is not utilized.

Minor visual changes to existing assets have also been introduced: the wallpaper first introduced in build 8375 has had its color temperature and saturation slightly adjusted, and the Windows Update icon has been updated to utilize its final design.

Adobe Flash Player

This build adds the third-party Adobe Flash Player multimedia plugin and its Control Panel applet to the x86 and x64 compiles of the operating system. It is not present in ARMv7 releases as Flash lacked a native port to ARM devices.

Printer test page

The printer test page now appears like the one in the RTM build. The design has not seen any changes since then and remains the same in later Windows versions up to this day. Following changes can be observed when comparing to the previous design:

  • The Windows 7-era logo has been replaced by a printer tile following the Metro design language.
  • The printer test page header text has been boldened and recolored to blue to match said tile in color.

Bugs and quirks

Intel Sandy Bridge CPU deadlocks

This build suffers from a clock timing-related hardware abstraction layer (HAL) bug that causes the operating system to gradually deadlock when it is run on Intel processors based on the Sandy Bridge microarchitecture while the system is installed on a solid-state drive.[9]

The KB2727113 update resolves the bug by replacing the HAL with a fixed version from the following GDR/LDR compiles:[10]

  • 6.2.8400.114 (winmain_win8rc_gdr.120625-1503) (GDR)
  • 6.2.8400.4219 (winmain_win8rc_ldr.120624-1501) (LDR)

Aero Lite transparency effects

When using the Windows Basic (Aero Lite) visual style, transparency effects can be enabled through the use of a bug in the Personalization Control Panel. To do so:

    • 1. Right-click the desktop and open up Personalization, then click on the "Window Color" link given at the bottom of the window. Keep the window open.
    • 2. Open a separate personalization window and apply the Windows Basic theme.
    • 3. Switch to the other personalization window that was opened at the start, uncheck and re-check the "Enable transparency" option and then click on the "Save changes" button. This will cause transparency effects to take effect.
