It was first shown running on an ARM-based Qualcomm Snapdragon QSD8660 SoC and NVIDIA Tegra 250 development kit at the [[w:Consumer Electronics Show#2011|CES 2011]] [[w:trade show|trade show]] to demonstrate the capabilities of the then-evolving [[w:ARMv7|ARMv7]] architecture, along with builds [[Windows 8 build 7898|7898]] and [[Windows 8 build 7900|7900]].<ref>[https://www.youtube.com/watch?v=rvzJmRBS84w Microsoft CES 2011 Windows OS Announcement - YouTube]</ref><ref>[https://www.youtube.com/watch?v=xKc_XGuvNIk Microsoft shows off ARM processors running Windows - YouTube]</ref> 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 [[w:Steven Sinofsky|Steven Sinofsky]] on 30 October 2022, along with video footage of builds [[Windows 8 build 7792|7792]] and [[Windows 8 build 8090|8090]] in issue 104 of their account of events during his time at Microsoft, titled ''Hardcore Software''.<ref>Sinofsky, Steven.

Edition / SKU Name ! Key |- | Starter{{efn|name="StarterExpl"|The Starter edition (and its N and E counterparts), last included in [[Windows 7]], had since been internally repurposed during [[Windows 8]] development to act as a base for new and existing Windows client SKUs. The Web Server edition would also be identically repurposed during development of its [[Windows Server 2012|server counterpart]] for both Desktop Experience and Core editions, although Standard Server would later take its place as the base for Server Core editions during the late development phases of [[Windows Server 2016]], specifically during [[Windows 10 Anniversary Update|Redstone 1]] development.}} | {{nowrap|7Q28W-FT9PC-CMMYT-WHMY2-89M6G}} |- | Starter E{{efn|name="StarterExpl"}} | {{nowrap|BRQCV-K7HGQ-CKXP6-2XP7K-F233B}} |- | Starter N{{efn|name="StarterExpl"}} | {{nowrap|D4C3G-38HGY-HGQCV-QCWR8-97FFR}} |- | Home Basic | {{nowrap|YGFVB-QTFXQ-3H233-PTWTJ-YRYRV}} |- | Home Basic E | {{nowrap|VTKM9-74GQY-K3W94-47DHV-FTXJY}} |- | Home Basic N | {{nowrap|MD83G-H98CG-DXPYQ-Q8GCR-HM8X2}} |- | Home Premium | {{nowrap|RHPQ2-RMFJH-74XYM-BH4JX-XM76F}} |- | Home Premium N | {{nowrap|76BRM-9Q4K3-QDJ48-FH4F3-9WT2R}} |- | Professional | {{nowrap|HYF8J-CVRMY-CM74G-RPHKF-PW487}} |- | Professional E | {{nowrap|3YHKG-DVQ27-RYRBX-JMPVM-WG38T}} |- | Professional N | {{nowrap|BKFRB-RTCT3-9HW44-FX3X8-M48M6}} |- | Enterprise | {{nowrap|H7X92-3VPBB-Q799D-Y6JJ3-86WC6}} |- | Enterprise E | {{nowrap|H3V6Q-JKQJG-GKVK3-FDDRF-TCKVR}} |- | Enterprise N | {{nowrap|BQ4TH-BWRRY-424Y9-7PQX2-B4WBD}} |- | Ultimate | {{nowrap|D4F6K-QK3RD-TMVMJ-BBMRX-3MBMV}} |- | Ultimate E | {{nowrap|TWMF7-M387V-XKW4Y-PVQQD-RK7C8}} |- | Ultimate N | {{nowrap|HTJK6-DXX8T-TVCR6-KDG67-97J8Q}} |} == 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 [[w:system-on-chip|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 <code>Windows\System32\config</code> directory (as <code>DRIVERS</code>). It is used by the Windows servicing stack to facilitate driver installation, and contains a list of relevant driver components,<!-- DRIVERS\DriverDatabase\DriverFiles --> hardware IDs,<!-- DRIVERS\DriverDatabase\DeviceIds --> references to driver metadata (INFs)<!-- DRIVERS\DriverDatabase\DriverInfFiles --> and definition data for each installed driver package.<!-- DRIVERS\DriverDatabase\DriverPackages --> === 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 [[Windows 8 build 7785|7785]] through [[Windows 8 build 7866|7866]] is disabled. *The branding observed within the watermark was temporarily changed to "Microsoft Pre-release Windows Operating System", in a stark contrast to [[Windows 7|its predecessors']] branding commonly seen in builds such as [[Windows 8 build 7779|7779]] and 7850. *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 [[Windows 7 build 7600.16385|RTM build]] of Windows 7, in place of the blue-green gradient Milestone 1 wallpaper that was used since [[Windows 8 build 7762|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 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 <code>twinui.dll</code>), 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. == Gallery == === UI-Interface === <gallery> Setup7867.png|Setup </gallery> === Internal recording === <gallery> Windows8-6.2.7867.0-SnapdragonDevKitInternal.png|Snapdragon SoC running this build's [[Paint]] application Windows8-6.2.7867.0-SnapdragonDevKitPaintDemoInternal.png|Closeup; full build tag visible </gallery> === CES 2011 still frames === <gallery> Windows8-6.2.7867-Desktop.png|Desktop 7867.png|Ditto, without [[DWM]] Win8-7867-1.jpg|Command Prompt Win8-7867-2.png|Start menu Windows8-6.2.7867-MediaPlayer.png|[[Windows Media Player]] </gallery> == Notes == {{notelist}} ==References== {{reflist}} [[Category:Windows 8 builds]]'
