Microsoft has now officially released the cumulative update KB5008212 for Windows 10 Version 2004 and 20H2/21H1/21H2 feature updates. The update is available via Windows Update or WSUS, but Microsoft has also released an offline installation package。
If you already installed last month's optional cumulative update, KB5008212 is just a security update. However, if you only installed the November 2021 Patch Tuesday Update, this cumulative update will also fix non-security issues with your Windows installation.
This is because the cumulative update includes fixes from previous months in a single package. If you skip a few past updates or optional patches for November 2021, installing today's update will also apply the fixes for those updates. Windows as a service ensures that a single monthly update can satisfy all missing updates.
This cumulative update also applies to Windows 10 Version 2004, but keep in mind that this will be the last patch received for this older operating system.
