INTEL MICROCODE UPDATES

Tables top to bottom contains the higher level of security / number of mitigations. Means the bottom table has the highest level of protection / mitigation.

These are partly part of the OS depending on the version; therefore, some Windows versions are not listed. If you use WSUS consider importing.

SERVICING STACK UPDATES

These special updates for maintain the servicing stack of Windows (which is responsible for updates, dism, adding and removing features etc) have to be installed before any regular update.
Currently Windows 10 1909, Windows Server 2019 and Azure Stack HCI OS have combined CUs, means the SSU is already integrated and will care for the correct installation order.

Article history:
03.11.2021 - Added information for Windows 11 21H1

13.10.2021 - Added information to Azure Stack HCI 21H2 release, other docs still not mention it except update history
07.10.2021 - Added Intel Microcode updates for all available threats and versions
07.10.2021 - Updated one available link for Windows 11. Update histories for 21H2 version W10/W11 are still missing
17.09.2021 - fixed some links pointing to a specific language
17.09.2021 - formatting, seperating LTSC from SAC for Windows 10, added SSUs
17.09.2021 - initial version

What's the reason and my motivation for this compendium even though Microsoft does have a dashboard?

1. It should help to find information faster according to a specific version.

2. you might notice while some links are duplicates, some other are unique and sometimes it is not easy to find the specific information according this a specific version. Well yes, bookmarks / MS Edge Collections exist.

3. Microsoft has a new CMS which has changed some links you might have saved. Feel free to create new collections in Edge.

4. Especially since, Windows Server 2022 and Azure Stack HCI OS appeared, some changes have been made. notice the update history page for Server 2022 is not included in the regular Windows Update history.

5. Azure Stack HCI OS is not listed on some other pages.

I hope you find this summary helpful. I will maintain this in future, as I also need this for internal reasons, I thought it could be good to have this public for own and other people references.
07.10.2021 - Updated one available link for Windows 11. Update histories for 21H2 version W10/W11 are still missing
07.10.2021 - Added Intel Microcode updates for all available threats and versions
