The original version of Windows 11 (also retroactively named version 21H2 and codenamed "Sun Valley") was released in October 2021. [1] [2] It carries the build number 10.0.22000. [3] It was retroactively named "version 21H2" by Microsoft per its naming conventions that are labeled "YYHX", with YY representing the two-digit year and X representing the half-year of planned release (for example, version 21H2 refers to builds which initially released in the second half of 2021). [4]
The first public preview build was made available to Windows Insiders who opted in to the Dev Channel on June 28, 2021. Notable changes in this version include:
The update has reached end of service on October 10, 2023 for Home, Pro, Pro Education and Pro for Workstations editions. [10] The Enterprise, Enterprise multi-session, IoT Enterprise and Education editions have reached end of service on October 8, 2024. [11]
