Special credit goes to gus33000 for helping dump this amazing gem and explaining what needs to be cleaned up before release
There are two versions of this build: one with the absolute original components (from the dump itself, including the x86-to-ARMv8 and Cobalt translation layers - install_NoCustomizations.wim), and another with all additions mentioned below (install_WithCustomizations.wim). Besides that, it is otherwise 1:1 functionally identical to Threshold 2 RTM.
Includes the following additions:
- MSM8994 SoC platform drivers, SBL1 boot blocks from eMMC
- Features a Windows SKU that was deprecated in the source tree and was no longer being actively developed by 2014 (Microsoft-Windows-CoreARMEdition/Windows RT 8.1)
- Early functioning versions of the x86-to-ARM and Cobalt (ARMv7) instruction translation layers (based off of Connectix Virtual PC PPC JIT code) [*1/*2]
- Full WoW64 subsystem built into OS [*1]
- .NET Framework 4, [*1] Common Language Runtime [*1/*3]
- Private builds of Windows Update client engine, AppX deployment server, AppX deployment utilities and an internal script for slipstreaming a small subset of Windows inbox applications targeting ARMv7 from build spew
- Debugging symbols for Windows OS core, AppX and WoW64 libraries with full type data
- AppX Test Root Certificate (expires on 1/1/2050)
- A small subset of inbox applications and some third-party applications downloaded from the Windows Store for XtA testing purposes
- ARMv8 WinDbg distro with internal debugger extensions
Due to technical limitations in the Windows servicing stack, the original AppX packages for this build cannot be properly re-provisioned into the latter image. As a result, the "WindowsApps" directory from the original eMMC dump has been provided in the "extras" directory for your convenience.
To install the inbox applications:
- Enable AppX sideloading (via the development mode toggle in Settings or line-of-business enablement/APPXLOB);
- Install the provided AppX test root certificate in the System32 directory into the Trusted Root Certification Authorities machine store, and;
- use PowerShell commandlet Add-AppxPackage or (Min)DeployAppX to install the inbox applications
Remember to install the provided Visual C++ and .NET runtimes in the WindowsApps directory before installing anything else first. You may use the provided (Min)DeployAppX executable to install these applications while the OS is running; documentation is provided within the tooling itself.
Footnotes:
*1: Not present in ServerARM64 builds from the same time period
*2: Cobalt translation layer is provided via a separate Windows SxS package only made available to Qualcomm partners (Microsoft-Windows-WowPack-CoreARM-arm64arm-Package)
*3: PowerShell does not run as some parts of the .NET CLR are missing
