For Windows client (which is what this Office Hours chat covers), you need to be on a supported version of Windows client. For Windows 11 Pro, this means you need to be on Version 24H2 or newer; for Windows 11 Enterprise, you need to be on Version 23H2 or newer. If you are on Windows 10 and have ESU, you will receive the certificate updates through Windows Update (see February 10, 2026—KB5075912 (OS Builds 19045.6937 and 19044.6937) - Microsoft Support for details).
