Microsoft has released Windows 10 KB5012599 and KB5012591 cumulative updates for versions 21H2, version 21H1, version 20H2 and 1909 to fix security vulnerabilities and resolve bugs.

The update has been published for November 2021 Update, May 2021 Update, and October 2020 Update. This update is not available for May 2020 Update (version 2004) if you use the consumer edition, but the same update will be offered on devices using enterprise or education SKUs.

Additionally, Microsoft warned in the bulletin that this is the second last update for versions 1909 and 20H2 (all editions) as support for the OS is set to end in May 2022.

Like every Patch Tuesday, this Windows 10 cumulative update is mandatory and can be installed by going to Settings, clicking on Windows Update, and selecting 'Check for Updates.'
