Windows 10 build 15035 is a build of Windows 10 Creators Update. It was leaked to BetaArchive on 24 November 2019. This build is currently notable to be the only leaked Windows 10 client build available for ARM (ARMv7) processors. It is possible to run this build under QEMU as well as on various devices that originally shipped with Windows RT or Windows 10 Mobile if the appropriate drivers are available and Secure Boot can be disabled. Although this build is not suitable for daily use, it has attracted some interest from the remaining users of ARM (ARMv7) devices as an unofficial upgrade from Windows RT or as a replacement for Windows 10 Mobile.

Applications[edit | edit source]

This build omits certain apps that were either not available for ARM (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[edit | edit source]

Although it is possible to install to 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 the store on this build does not work. The lists below detail the preinstalled versions and the latest known versions of various Microsoft apps that will work with this build as of July 2020.

Additional software[edit | edit source]

  • 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 /
  • This build supports all versions of Office 2013 RT which were previously included with Windows RT, if installed on this build Windows Update will work to provide any available updates for Office 2013 RT.
  • Most software that was recompiled for jailbroken Windows RT devices will run on this build.

Bugs[edit | edit source]

This build 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
  • Cameras will not work even with the appropriate app and drivers installed on Surface RT devices 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]
  • 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.
  • On some devices the Screen Brightness setting does not persist after a reboot and Automatic Brightness does not always function correctly.
  • On some devices Night Mode may not always function correctly.
  • The background color for windows is gray instead of white.

Driver compatibility[edit | edit source]

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 Surface RT and Surface RT 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 Surface tablets. On the Surface RT 2 (may also apply to Surface RT), 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. Later versions of the Surface RT 2 USB recovery media in particular may contain version 9600.16497 of sdbus driver which will trigger the error.
  • 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.

Expired digital signatures[edit | edit source]

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\tools\ and overriding the Driver Signature Enforcement Check when prompted.

Restrictions[edit | edit source]

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.

Fake builds[edit | edit source]

Following the leak of this build to BetaArchive, two pre-prepared images have been distributed for Surface devices in both Chinese and English languages.

  • An image released in January 2020 has been rebadged as Windows RT 10, however this is not a genuine SKU of Windows 10.
  • A highly modified image released in May 2020 has been rebadged as build 17763, while this image does contain components from later builds likely obtained from Windows PE it is in fact still build 15035.
