Windows 11 (26H2) IoT Enterprise 26300.8758 Insider Experimental x64 (MUI - 17)

Windows IoT, short for Windows Internet of Things and formerly known as Windows Embedded, is a family of operating systems from Microsoft designed for use in embedded systems. Microsoft has three different subfamilies of operating systems for embedded devices targeting a wide market, ranging from small-footprint, real-time devices to point of sale (POS) devices like kiosks. Windows Embedded operating systems are available to original equipment manufacturers (OEMs), who make it available to end users preloaded with their hardware, in addition to volume license customers in some cases.
In April 2018, Microsoft released Azure Sphere, another operating system designed for IoT applications running on the Linux kernel.
