Windows 10 November 2021 Update (also known as version 21H2) is a feature update to Windows 10 released on 16 November 2021.[1] Despite sharing the same version string of "21H2" with Windows Server 2022 and the initial release of Windows 11, it is a cumulative update for Windows 10 May 2020 Update and later updates.

It is the last Windows feature update to use the month and year naming scheme for the official update name which has been in use since Windows 10 April 2018 Update as feature updates starting with Windows 11 2022 Update and Windows 10 2022 Update only use the year naming scheme as Microsoft switched the operating system to an annual release cadence starting with the release of Windows 11. It is also the last version of Windows 10 to have a Long-Term Servicing Channel (LTSC) variant.
