Microsoft has finalized the latest feature update of its older desktop operating system, calling it Windows 10 November 2021 Update, version 21H2. Similar to the last few feature updates, the Windows maker has focused primarily on performance and feature improvements instead of introducing any massive new features. Windows 10 November 2021 Update will also be an easy-to-install update, just like versions 21H1 and 20H2.

Windows 10 version 21H2, similar to the last two versions, shares a common core operating system and an identical set of system files with the May 2020 Update, version 2004. This means that any new features and improvements in Windows 10 November 2021 Update will be pushed to those running versions 2004, 20H2, and 21H2 through a monthly quality update and will be turned on using an enablement package.
