Four screenshots of this build's x86 checked/debug compile in the Prerelease SKU were first shared to the BetaWiki Discord on 29 May 2020; a WIM image dump of a Surface RT containing the [[w:ARMv7|ARMv7]] compile of this build's Ultimate SKU was later shared on 19 May 2023,<ref name="IA_ARMv7">https://archive.org/details/6.2.8061.0.fbl_core1_soc.110803-1830_ARM32_WIMDump</ref> followed by a staged WIM image of this build's Prerelease N SKU on 28 January 2024.<ref name="IA_ARMv7"/> The original partner drop for both the retail and debug client releases of this build's unstaged ARMv7 installation media and [[Preinstallation Environment]], including software development kits and raw symbol sets, were eventually uploaded on 13 July 2024, while this build's x86 counterpart original partner drop was uploaded on 19 October 2024. This is the last known build to use the [[Windows 7]] branding on the system properties. It is notable for being one of 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. The initial available copy of this build's ARMv7 Ultimate SKU image was assembled from scratch via unstaged installation media, utilizing the [[Preinstallation Environment]] for [[Windows 8 build 8175.5|build 8175.5]] to facilitate the install. == Editions and keys == The following SKUs are installable in this build: {| class="wikitable" ! Edition / SKU Name ! Key |- | Starter{{efn|name="StarterExpl"|The Starter edition (and its N counterpart), 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.}}{{efn|name="ARM32OrStaging"|Only available in the unstaged ARM32 or x86 debug compiles or via manually staging it on the x86 retail image.}} | {{nowrap|7Q28W-FT9PC-CMMYT-WHMY2-89M6G}} |- | Starter N{{efn|name="StarterExpl"}}{{efn|name="ARM32"|Only available on the unstaged ARM32 or x86 debug compiles.}} | {{nowrap|D4C3G-38HGY-HGQCV-QCWR8-97FFR}} |- | Home Basic{{efn|name="ARM32OrStaging"}} | {{nowrap|YGFVB-QTFXQ-3H233-PTWTJ-YRYRV}} |- | Home Basic N{{efn|name="ARM32"}} | {{nowrap|MD83G-H98CG-DXPYQ-Q8GCR-HM8X2}} |- | Home Premium{{efn|name="ARM32OrStaging"}} | {{nowrap|RHPQ2-RMFJH-74XYM-BH4JX-XM76F}} |- | Home Premium N{{efn|name="ARM32"}} | {{nowrap|D3PVQ-V7M4J-9Q9K3-GG4K3-F99JM}} |- | Professional{{efn|name="ARM32OrStaging"}} | {{nowrap|HYF8J-CVRMY-CM74G-RPHKF-PW487}} |- | Professional N{{efn|name="ARM32"}} | {{nowrap|BKFRB-RTCT3-9HW44-FX3X8-M48M6}} |- | Enterprise{{efn|name="ARM32OrStaging"}} | {{nowrap|H7X92-3VPBB-Q799D-Y6JJ3-86WC6}} |- | Enterprise Evaluation{{efn|name="ARM32OrStaging"}} | {{nowrap|BNMMY-9D8F2-TKGQ6-BT8DJ-JFCMG}} |- | Enterprise N{{efn|name="ARM32"}} | {{nowrap|BQ4TH-BWRRY-424Y9-7PQX2-B4WBD}} |- | Enterprise N Evaluation{{efn|name="ARM32"}} | {{nowrap|KJC88-XWNCH-C4F7V-8X4DM-XBPMH}} |- | Ultimate{{efn|name="ARM32OrStaging"}} | {{nowrap|D4F6K-QK3RD-TMVMJ-BBMRX-3MBMV}} |- | Ultimate N{{efn|name="ARM32"}} | {{nowrap|HTJK6-DXX8T-TVCR6-KDG67-97J8Q}} |- | Developer Preview (<code>Prerelease</code>) | {{nowrap|H9VCT-63NFW-FWHDR-F4J43-972K8}} |- | Developer Preview N (<code>PrereleaseN</code>){{efn|name="ARM32"}} | {{nowrap|T87VG-N82DX-9Q7G4-67CHR-KBPMB}} |- | Developer Preview ARM (<code>PrereleaseARM</code>){{efn|name="ARM32OrStaging"}} | {{nowrap|D9HNY-JTJDK-BQM84-K3VTB-JK4D3}} |} == New features and changes == === Interface === The [[start screen]]'s default layout has been updated to feature a new set of pinned applications. A new splash screen icon and major revisions to the descriptions of certain options (and their sections) in the [[Immersive Control Panel]] have been introduced, and slight design changes have been made towards the [[Windows Store]] application, primarily the addition of a back button in the main user interface as well as an updated application tile design. The touch-optimized [[Remote Desktop Connection]] client has been rebranded to simply ''Remote Desktop'' and its overall color palette and splash screen updated, although functionality largely remains identical. Immersive modal dialogs now carry the background color of the user's chosen accent color by default. === Miscellaneous === * The background color seen when [[bugcheck]]s are invoked has been changed to cerulean, making the overall design now largely reminiscent of the one found within [[Windows 8 build 9200 (win8_rtm)|the RTM build]]. * An issue with the Microsoft Basic Render in ARM32 builds [[Windows 8 build 7996 (fbl_multimedia_media_sndproc)|7996]]-[[Windows 8 build 8038|8038]] (where the text has some black stuff around it) has been fixed in this build. == Compatibility == This build contains [[w:ARM Cortex-A9|ARM Cortex-A9]] timer hardware abstraction layer extensions for the [[w:NVIDIA Tegra|NVIDIA Tegra]] 2/3 [[w:System-on-a-chip|systems-on-a-chip]] and the [[w:OMAP#OMAP 4|Texas Instruments OMAP4]] SoC line. A HAL extension for the ARM SP804 dual timer is also included. USB 2.0 kernel debugger extensions for the Tegra and OMAP4 SoCs are also available out-of-box, but are untested as of writing. == Patched/modified files == The following modified files are present in the initial ARM32 image dump: * <code>winload.efi</code> is from <code>[[Windows 8 build 8129|6.2.8129.0 (fbl_core1_soc.111006-1700)]]</code> and additionally has had signature checks patched out. This is because the EFI firmware parameters substructure of the boot library (passed to the entry point of a boot application) was later changed in [[Windows 8 build 8112 (fbl core1 soc)|build 8112 (fbl_core1_soc)]]; attempting to load older boot applications in a boot manager from builds 8112 onward (or vice versa) will result in a crash due to differing element offsets. The patched binary allows the build to be booted using a production-signed boot manager (using <code>donothingpolicy.pol</code> and <code>NOINTEGRITYCHECKS</code> enabled in the machine's boot configuration data). ** The original binary from build 8061 is located in <code>Windows\WinSxS\Backup\arm_microsoft-windows-b..vironment-os-loader_31bf3856ad364e35_6.2.8061.0_none_e22fc5a8e03359c9_winload.efi_75834aa0</code> * <code>acpi.sys</code> is from <code>6.2.8129.0 (fbl_core1_soc.111006-1700)</code> (unmodified, valid signature). The ACPI implementations in builds 8061 through [[Windows 8 build 8112 (fbl core1 soc)|8112 (fbl_core1_soc)]] are not compatible with [[w:Surface RT|Surface RT]] hardware, and therefore require a binary replacement to function properly on such hardware. ** The original binary from build 8061 is located in <code>Windows\WinSxS\arm_acpi.inf_31bf3856ad364e35_6.2.8061.0_none_a991cf7a419448c9\acpi.sys</code> * <code>partmgr.sys</code> has two jumps patched to prevent functions from returning <code>STATUS_MEDIA_WRITE_PROTECTED</code>. The original version is still in the <code>Drivers</code> directory, named <code>partmgr.old</code>. * <code>testplugin.dll</code> is signed by a certificate chain named ''DesktopApp''. This file can be restored to its original state by removing the signature. None of the above modifications are required to boot this build under QEMU, however <code>hal.dll</code> will have to be patched in order to recognize the emulated timers. == Emulation == {{Collapse top|title=Guide for running the ARM32 compile of this build under emulation:}} {{:Document:Emulating Windows 8 build 8061 ARM32}} {{Collapse bottom}} == Bugs and quirks == === SD bus driver write protection (Surface RT)=== [[w:MultiMediaCard|MultiMediaCard]]-based storage mediums (such as [[w:Secure Digital|Secure Digital]] (SD) cards and [[w:eMMC|eMMC]]s) are mounted by the operating system as read-only/write-protected file systems on the Surface RT; the build must therefore be booted under a non-MMC medium such as an external USB mass storage device or a [[Hyper-V]] virtual hard disk (VHD) image. To mount the eMMC as a read-write filesystem, the <code>sdbus.sys</code> function <code>SdhcIsWriteProtected</code> must be patched to return 0 (and the PE checksum fixed); patch file offsets <code>0x138</code> and <code>0x6c24</code> to <code>db e2 01</code> and <code>00 20 70 47</code>, respectively. This issue does not happen under emulation. === Windows Setup === Rendering artifacts may appear on the product key page during the [[out-of-box experience]]. === Applications === * Windows Runtime applications' titles are not printed correctly and instead spew the full application user model ID (<code>AumId</code>). === Desktop Window Manager === * Disabling and re-enabling composition and then invoking the left-hand Charms menu may cause the Desktop Window Manager to crash and generally destabilize unless the right-hand Charms bar is invoked. === Miscellaneous === * Attempting to shut down the system may cause the system shell to crash with an invalid memory read exception if the user never exits out of the start screen first presented to the user under a [[redpill]]ed environment. * Logging off might result in a <code>DRIVER_OVERRAN_STACK_BUFFER</code> bugcheck. ===ARM32-compile specific=== ====Applications==== * ''[[Chess Titans]]'' and ''[[Mahjong Titans]]'' will fail to launch as the respective English language pack resources for the built-in [[Windows 7]] premium games are not present in the image. * Newly loaded web pages rendered by [[Internet Explorer]] may often use the wrong background colors, presenting shades of random colors in place of the standard white. * Turning on administrative tools in the start screen preferences sub-menu within the Settings charm causes the Explorer shell to crash. ====Desktop Window Manager==== * [[Desktop Window Manager]] software-based compositing does not work by default as the underlying implementation always assumes all built-in GPU drivers to be incompatible, unless a Terminal Services client such as [[Remote Desktop]] is used. The main DWM executable <code>dwm.exe</code> can be patched to force render even with incompatible hardware. A workaround is discussed in the above patching guide. * The DWM software renderer implementation in this build is subject to major performance issues and may end up becoming out-of-sync with the actual desktop session. Disabling window animations may help improve performance at the cost of visual quality. * Animations in the [[Start screen]] may not complete properly. ====Miscellaneous==== * This build cannot be powered off normally as it hangs during the shutdown process. Manually hold down the power button to power off the device instead. Shutting down can also sometimes result in a <code>BAD_POOL_CALLER</code> bugcheck. == Gallery == === ARM32 compile === <gallery> File:Windows8-6.2.8056-Boot.png|Boot screen Windows8-6.2.8061.0-StartMenu.png|[[Start menu]] Windows8-6.2.8061.0-SystemProperties.png|[[Control Panel]] system properties section Windows8-6.2.8061.0-InternetExplorerRenderBug.png|Internet Explorer webpage rendering bug Windows8-6.2.8102-BSOD.png|System crash </gallery> === Setup and OOBE === <gallery> Windows8-6.2.8061.0-SetupHWDetect.png|Hardware detection (second phase of setup) Windows8-6.2.8061.0-OOBERegionSelection.png|Region and language settings Windows8-6.2.8061.0-OOBEComputerNameNonRP.png|Computer name Windows8-6.2.8061.0-OOBEProductKey.png|Product key entry Windows8-6.2.8061.0-OOBEEULA-NONRP.png|End-user license agreement Windows8-6.2.8061.0-OOBEAccountNonRP.png|Account credentials Windows8-6.2.8061.0-OOBEUpdatesNonRP.png|[[Windows Update]] settings Windows8-6.2.8061.0-OOBETimeDateNonRP.png|Time and date settings </gallery> === Redpilled state === <gallery> Windows8-6.2.8061.0-LockScreenRP.png|Lock screen Windows8-6.2.8061.0-LogonScreenRP.png|Logon screen Windows8-6.2.8061.0-StartScreen.png|Start screen Windows8-6.2.8061.0-StartScreenSmallApps.png|Start screen in semantic zoom mode Windows8-6.2.8061.0-StartScreenUserTile.png|User tile dropdown menu Windows8-6.2.8061.0-Desktop-RP.png|Redpilled desktop Windows8-6.2.8061.0-CharmsMenu.png|Left-hand charms menu Windows8-6.2.8061.0-CharmsBar.png|Charms bar Windows8-6.2.8061.0-VanUI.png|View Active Networks UI Windows8-6.2.8061.0-WindowsExplorerRP.png|[[Windows Explorer]] Windows8-6.2.8061.0-MiniTaskmgrRP.png|[[Task Manager]] in compact mode Windows8-6.2.8061.0-TaskmgrRP.png|Task Manager in advanced mode Windows8-6.2.8061.0-ImmersiveControlPanel.png|[[Settings|Immersive Control Panel]] Windows8-6.2.8061.0-ImmersiveIE.png|Immersive [[Internet Explorer 10]] Windows8-6.2.8061.0-WindowsStore.png|[[Windows Store]] Windows 8-6.2.8061.0-BootIM.png|Boot options </gallery> ==== Metro OOBE ==== <gallery> Windows8-6.2.8061.0-OOBEProductKeyRP.png|Product key entry Windows8-6.2.8061.0-OOBEEULARP.png|End-user license agreement Windows8-6.2.8061.0-OOBEOnboardingRP.png|Initial onboarding animation Windows8-6.2.8061.0-OOBEComputerNameRP.png|Personalization Windows8-6.2.8061.0-OOBEPrivacySettingsRP.png|Privacy settings Windows8-6.2.8061.0-OOBEPrivacySettingsAdvancedRP.png|Advanced privacy settings Windows8-6.2.8061.0-OOBEPrivacySettingsAdvanced-2RP.png|Ditto.
