We mentioned this around last month’s Patch Tuesday, but we mention it again: Microsoft Corporation 425,43 +5,25 +1,25% will “End of Service’ Windows 10 21H1 (May 2021 update) on December’s Patch Tuesday (December 13th). This means December will be the last time Microsoft will offer updates for the Window 10 21H1 build. This does not mean support for Windows 10 is ending or you need to install Windows 11 to continue getting updates. You may continue to use Windows 10 and get updates through October 2025. All you need to do is install the update for the latest Windows 10 build (22H2) released in October 2022.
Microsoft announced the availability of Windows 10 22H2 (aka the Windows 10 2022 Update) on October 18, now rolling out to all eligible devices.
This feature update can be installed via Windows Update by going to Settings > Update & Security > Windows Update and clicking the “Check for updates” button.
