For some reason this exists...
Despite previous statements to the contrary, in January 2015 Microsoft announced that Windows RT devices would not receive an upgrade to Windows 10 and they would remain on Windows RT 8.1. Following this announcement the devices were effectively abandoned.
During a security breach at Microsoft in early 2017 the Enterprise SKU of Windows 10 Creators Update build 15035 for ARMv7 was obtained, after a period of limited circulation the build was eventually publicly leaked to BetaArchive on 24th November 2019. At the time of writing this is the only leaked Windows 10 client build available for ARMv7 devices.
Although this build is not considered suitable for daily use, it has attracted some interest from the remaining users of ARMv7 devices as an unofficial upgrade from Windows RT.
Windows 10 Build 15035 (Surface 2)
The last known version of the Store to provide somewhat normal functionality is 11803.1001.1113.0.
Although it is possible to install more recent versions of the Microsoft Store it will only function to install updates for apps that are manually installed or apps already purchased and available on the users account, the purchase and installation of new apps directly from recent versions of the store on this build will not work.
This build omits certain apps that were either not available for ARMv7 processors at the time or were simply excluded from the build for other reasons. Although the included apps are limited there are numerous additional apps still available as well as updates for the preinstalled apps that are compatible with this build.
Updates to Included Apps
In its original release the following apps are included:
The included apps may be updated to the following versions:
These common apps can be installed without modification to provide a more complete experience, however it should be noted that some may be inoperable due to age or the services they rely on being retired.
Internet Explorer 11 is not installed or included in the Windows image as a Feature on Demand package by default however it is available as a separate optional package on the installation media in \sources\sxs which can be installed by running the command below:
DISM.exe /Online /Add-Package /PackagePath:microsoft-windows-internetexplorer-optional-package.cab
Office 2013 RT appears to work normally on Build 15035 and if installed Windows Update will work to provide any available updates however activating Office requires license modification.
Office 2013 RT Home & Student Plus (Surface 2)
Windows 10 Build 15035 contains a few notable bugs:
- The User Account Control user interface is broken, leading to issues starting programs requiring administrative privileges. Disabling UAC using the registry is mandatory to run these programs, this can be achieved by applying the registry entry below:Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]"EnableLUA"=dword:00000000
- Cameras will not work even with the appropriate app and drivers installed due a missing registry entry, this can be resolved by applying the registry entry below:Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform]"EnableFrameServerMode"=dword:00000000
- Using Microsoft Management Console (MMC) snap-ins can cause a BSOD error (PANIC_STACK_SWITCH). This issue occurs most commonly with Event Viewer and Task Scheduler while occurring somewhat less frequently with Disk Management however it may manifest at random with any MMC snap-in.
- The Screen Brightness setting does not persist after a reboot and Automatic Brightness does not always function correctly.
- Night Mode does not function correctly.
- The background colour for windows is gray instead of white.
This build is for the most part compatible with drivers originally intended for Windows RT aside from the following exceptions:
- This build technically does not support NVIDIA Tegra processors, like the ones found in the ASUS VivoTab RT, Lenovo IdeaPad Yoga 11, Microsoft Surface RT and Surface 2. The sdbus driver, responsible for providing an interface layer with the eMMC dropped support for the NVIDIA storage controller during Windows 10 development. You can however replace the driver with the one from Windows RT 8.1 build 9600.16384 to make the build boot on Tegra devices. Using a version of sdbus newer than 9600.16384 will conflict with the nvpep driver causing a BSOD error (IRQL_NOT_LESS_OR_EQUAL) on boot.
- This build does not support legacy touch drivers built for Windows 8 RTM. Loading these drivers will cause the OS to register touch inputs in the top left corner of the screen.
- This build does not support the Nokia Lumia 2520 Qualcomm Power Engine Plugin driver. Loading a newer driver for the Snapdragon 800 is mandatory.
Numerous issues are caused when attempting to use this build beyond its expiry date due to various digital signatures being outside of the validity period, this is normal and is by design once the build reaches its expiry date or when installed after it. Examples of some of the issues caused by installing or running this build with current date set are listed below.
- The legacy Windows Defender UI (MSASCui.exe) is not functional and will terminate with a critical error (0x800b0101).
- The Diagnostics Troubleshooting Wizard is not functional and will terminate with a critical error (0x800b0101).
- Neither Microsoft Print To PDF or Microsoft XPS Document Writer will be available after installation. Should these be required both drivers can be manually installed from
\Windows\System32\spool\toolsand overriding the Driver Signature Enforcement Check when prompted.
Although it is not an edition of Windows RT, this build has inherited some of the restrictions present in Windows RT. When certain Windows RT restrictions were established they were applied not by SKU but were instead applied to a specific architecture, in this case ARM (ARMv7). Issues known to be caused by this are:
- User defined start-up programs are not available.
- Incoming Remote Desktop connections are not available.
Microsoft reportedly continued to build complete Windows 10 installation media for ARMv7 until build 19041 (Windows 10 May 2020 Update) however builds other than 15035 remain un-leaked.
Two pre-prepared images have been distributed for Surface devices in both Chinese and English languages.
- An image released in January 2020 has had its Edition modified to Windows RT 10 and Version increased to 1703 whilst retaining the original build number.
- A highly modified image based on this build was released in May 2020 which has had its build number modified to 17763, while this image does contain components from later builds likely obtained from Windows PE it is in fact still build 15035.
