Microsoft has released Windows 10 21H2, also known as the November 2021 Update, and it is available to users running Windows 10 2004 or later as an optional update in Windows Update.

The Windows 10 21H1 feature update is a limited release with only a few new features, primarily directed at business users. However, as this is the latest release of Windows 10, and Windows 10 2004 reaches the end of support next month, it is recommended that users install the new feature update.
