While you shouldn’t rush the new feature update to avoid potential bugs and other problems during the early days, the update has been out for some time, and it’s now fully available, and you can upgrade manually in at least two ways using Windows Update and the Media Creation Tool. Windows 10 November 2021 Update (21H2) has been available since November 16, 2021, and you can upgrade to the latest version manually whether you have version 21H1, 20H2, 2004, 1909, or an older release.
