Microsoft has resolved challenges related to the installation of Extended Security Updates (ESU) on Windows 10 devices through an out-of-band update, KB5071959. Issues arose after the end of Windows 10's official lifecycle, including erroneous notifications about the operating system's end-of-life for users enrolled in the ESU program, affecting Enterprise editions like LTSC 2021 and LTSC IoT 2021. This problem has been fixed with a cloud configuration update. The ESU program is the final tier of support for Windows 10, crucial for maintaining security against emerging threats for the next one to three years. Enrollment in the ESU program requires a financial commitment or enrollment through Windows Backup, and users must be signed into a Microsoft account.
