Windows 8 build 7867

Windows 8 build 7867 is an internal build of Windows 8. It was first shown running on an ARM-based Qualcomm Snapdragon QSD8660 SoC and NVIDIA Tegra 250 Harmony Reference Platform at the CES 2011 trade show to demonstrate the capabilities of the then-evolving ARMv7 architecture, along with builds 7898 (fbl_core1_kernel_npc_ext) and 7900.Microsoft CES 2011 Windows OS Announcement - YouTubeMicrosoft shows off ARM processors running Windows - YouTube A low-quality camera recording of the build which showed demonstration of the Paint application running on the same Qualcomm SoC prior to the event was later uploaded by former Windows division president Steven Sinofsky on 30 October 2022, along with video footage of builds 7792 and 8090 in issue 104 of their account of events during his time at Microsoft, titled Hardcore Software.Sinofsky, Steven. 104. //build It and They Will Come (Hopefully), Hardcore Software: Inside the Rise and Fall of the PC Revolution. 30 October 2022.Various Authors. Windows 8 on NVIDIA Tegra running in Microsoft labs, Hardcore Software: Inside the Rise and Fall of the PC Revolution. Late 2010—20 August 2011.
The original partner drop for both the retail and debug client releases of the build's unstaged ARMv7 installation media and Preinstallation Environment, including software development kits and raw symbol sets for Nvidia were eventually uploaded on 8 September 2024. The Qualcomm drop was uploaded on 4 December 2024, followed by the Texas Instruments drop on the BetaWiki Discord Server 2 days later.
It is notable for being one of the few Windows builds to be made available in the form of unstaged installation media; all client editions available in the Windows 8 source tree at the time of compilation (albeit labeled as Longhorn, a holdover that was never corrected internally) are available for the user to pick from and install during setup, in turn building a complete Windows image from scratch from a set of components through the use of the Windows Component-Based Servicing (CBS) stack.

== New features and changes ==
=== HAL extension support ===
This is the earliest available build of Windows to support hardware abstraction layer extensions, which allow platform developers to quickly provide support for system-on-chip devices by adding interfaces for interrupt timers and controllers, as well as direct memory access (DMA) controllers.
=== Driver management ===
System drivers now use a dedicated registry database located in the Windows\System32\config directory (as DRIVERS). It is used by the Windows servicing stack to facilitate driver installation, and contains a list of relevant driver components, hardware IDs, references to driver metadata (INFs) and definition data for each installed driver package.
=== CES 2011 demonstration differences ===
Various aspects of this build were either changed or disabled during the CES 2011 demonstration, two of which are likely a result of file replacement originating from later builds originating from shell development branches:
*The User Tile seen in builds 7785 through 7866 is disabled.
*The branding observed within the watermark was temporarily changed to "Microsoft Pre-release Windows Operating System", in a stark contrast to its predecessors' branding commonly seen in Milestone 1 builds.
*The Windows Fingerprinting Service is disabled, as evidenced by the lack of the Microsoft Confidential leak warning in the watermark and the missing EULA hash.
*The desktop background was changed to the one seen in the RTM build of Windows 7, in place of the blue-green gradient Milestone 1 wallpaper that was used since build 7762.
== Bugs and quirks ==
=== ARMv7 port differences ===
Due to the earliness of the ARMv7 port, aspects of the operating system that exist in x86 compiles do not exist on ARM:
* The older CMIv2-style component store (containing the binaries used to assemble the Windows Foundation base image) is present alongside the newer Windows side-by-side (SxS) component store.
* The .NET Framework is not present, despite components depending on the Common Language Runtime (such as PowerShell) being included.
** Most applications that rely on .NET Framework such as the Snipping Tool and Windows Media Center do not exist.
* The Warbird obfuscation layer was not yet ported at this stage in development - components relying on it, such as the Metro shell (provided by twinui.dll), security components (such as the Next-Generation Secure Computing Base (NGSCB) security processor drivers) and software licensing components are not obfuscated.
* The Windows Search indexing engine does not exist at this stage in development.
