Patchday: Windows 10 Updates (September 12, 2023)

[German]On September 12 (second Tuesday of the month, patchday at Microsoft), several cumulative updates were released for the supported Windows 10 builds (from RTM version to current version) as well as for the Windows Server counterparts. Here are some details on the respective security updates for Windows 10.

A list of the updates can be found on this Microsoft website. I've pulled out the details below. Since March 2021, Microsoft has been integrating Servicing Stack Updates (SSUs) for newer Windows 10 builds into the cumulative update. March 2023 is the last time preview updates will be available for older Windows 10 builds.

Updates for Windows 10 Version 21H1-22H2

For the Windows 10 versions mentioned above, Microsoft provides only one update package, which is mentioned below.

Cumulative update KB5030211 raises the OS build for all Windows 10 variants to 1904x.3448 – at 21H2, only the Enterprise variant gets the update. The update only contains security fixes, but no new operating system features. A list of fixes can be read in the article Windows 10 22H2 Preview Update KB5029331 (August 22, 2023), these fixes have been adopted yes. For the cumulative update, it simply states:

This update addresses security issues for your Windows operating system.

Microsoft also notes that this update makes quality improvements to the servicing stack (is responsible for Microsoft updates). This update is automatically downloaded and installed by Windows Update, but is also available from the Microsoft Update Catalog and via WSUS and WUfB. Note the installation instructions and known issues described in the support post.

As of June 13, 2023, support for Windows 10 21H2 Home and Professional ended – in the future, only Windows 10 22H2 will then be supported with updates in unmanaged environments. The release of this version is done by the enablement update KB5003791.
