Microsoft's Windows Embedded and Windows IoT products began in 1999 with Windows NT Embedded, codenamed Impala. Windows XP Embedded, known as Mantis, expanded toolkit capabilities with tools like Target Designer and Component Designer. Windows Embedded POSReady 2009 catered to the point-of-sale sector, maintaining a consistent kernel across consumer and embedded versions. Windows CE supported mobile devices with various architectures and reached its end of support in 2023. Windows Embedded 7 Standard and Windows 7 for Embedded Systems required special licensing agreements. Windows Embedded Standard 8 did not succeed in the industrial market, while Windows 10 IoT Enterprise, launched in 2015, introduced LTSB/LTSC options with a decade of security updates. A tiered licensing structure was introduced for Windows 10 IoT Enterprise, accommodating different CPU performances. The Base license allowed Windows 10 IoT Enterprise on industrial Arm devices, specifically the NXP i.MX8 family. Windows 11 21H2 established the General Availability Channel for IoT, with Windows 11 IoT Enterprise 2024 LTSC set to debut in May 2024. Windows 11 IoT Enterprise LTSC supports Arm Qualcomm CPUs and introduces features like USB 4.0 and Wi-Fi 6/7 support, along with a commitment to 10 years of security updates. Windows 10 IoT Enterprise 2021 LTSC will remain supported until 2031.
