Microsoft Windows for Windows Developer Program for IoT,^[1] also known as Windows 8.1 IoT Core, is a heavily stripped-down version of the Windows 8.1 operating system designed for Intel Galileo, an x86-based Arduino-compatible development board. It was announced during Build 2014^[2] and subsequently released on 16 July 2014.

The operating system features a minimal subset of Win32 APIs as well as a lightweight version of the .NET Common Language Runtime and a near-complete (albeit non-functional) version of the Windows Runtime for use in IoT application development. It is meant to be accessed over a local network via Telnet.

Windows 8.1 IoT Core only officially supported developing console applications using the Visual C++ 2013 toolchain, although support for JavaScript and WinRT applications were additionally planned but not realized. Tutorials for building three basic sample applications as well as sources for legacy API call forwarders were released as part of the operating system.

It was quickly succeeded by Windows 10 IoT Core in late 2015, which added support for a wider pool of development boards, proper WinRT (and by extension UWP) support, as well as graphical and text-based interfaces for embedded applications for both headed and headless setups.
