Windows 10 KB5008212

This year’s last Windows Update is now available for Windows 10 2004, v20H2, v21H1, and version 21H2. The patch is available via Windows Update or WSUS, but Microsoft has also published direct download links for Windows 10 KB5008212 offline installers.

KB5008212 is a security-only update if you have already applied last month’s optional cumulative update. However, if you only have November 2021 Patch Tuesday update installed, this cumulative update will also fix non-security issues with your Windows installation.

That’s because a “cumulative” update includes fixes from previous months in a single package. If you skipped the last few updates or November 2021’s optional patch, installing today’s update will also apply fixes from those updates. Windows as a service approach ensure that a single monthly update is enough for all missing updates.

If you’ve already updated to Windows 10 version 21H2 (November 2021 Update), you will get Build 19044.1415 as part of today’s patch. If you’re on 21H1 aka May 2021 Update you’ll receive Build 19043.1415 with the same set of bug fixes and improvements.

For those on version 20H2, the build number is 19042.1415 and it makes no difference to changelog.

Microsoft has also published the update for Windows 10 version 2004, but remember that this would be the last patch for the old OS. As you’re probably aware, Windows 10 consumer editions are supported for 18 months and enterprise or education editions can get updates for 30 months. Windows 10 v2004 consumer edition has reached EOL today.

If you check for updates today, you’ll see the following update:

Version 2004 reaches the end of support

Microsoft has confirmed the end of support for Windows 10 version 2004, a version of the OS that was announced in early 2020. Microsoft has already started upgrading users to the most recent version of the OS, and the company will ignore your Windows Settings if you’re on Home or Pro edition.

For those unaware, Microsoft changed its approach towards Windows 10’s support and update process in 2019. Microsoft confirmed newer feature updates will be forced onto users PC when the company is about to cease support for a particular Windows version.

In other words, if you’re still on Windows 10 version 2004 for whatever reason, you’re going to be automatically upgraded to version 21H1.

Microsoft is also planning to push Windows 10 version 21H2 and Windows 11 to more users in the coming weeks.
