by

KB5030278 is the cumulative monthly rollup update for Windows Server 2012 for the month of September 2023. The update was released on 12th September 2023 under the ‘Patch Tuesday’ project of Microsoft.

Salient points

  • KB5030278 is a cumulative update that supersedes KB5029295. KB5029295 was released in August 2023. You can read more about KB5029295 on this page.
  • KB5030278 also includes all the changes that are part of the security update KB5030279 for Windows Server 2012.
  • We strongly recommend installing or preferring KB5030278 instead of the KB5030279 security update. This is because the monthly rollup updates are cumulative in nature. Security-only updates are standalone updates.
  • A new Servicing Stack Update has also been released for Windows Server 2012 on 12th September 2012.
  • Before deploying KB5030278, please install the latest Servicing Stack Update KB5030330 on Windows Server 2012.
  • There are 12 security vulnerabilities that have been disclosed for Windows Server 2012 as part of the September month’s security bulletin released by Microsoft.
  • There are no CRITICAL vulnerabilities on Windows Server 2012 as per the September security bulletin.
  • There are no zero-day threats that affect Windows Server 2012 as per the September security bulletin.
  • The issue with language packs remains unresolved and continues to affect Windows Server 2012. If you install a language pack after installing KB5030278 monthly rollup update, you will need to redeploy the monthly rollup update.

It may be a good idea to understand that Windows Server 2012 becomes End-of-support in October 2023. The Extended Security Updates or ESUs are made available for a period of 3 years. Using the ESUs will extend security update coverage for Windows Server 2012 for a period of 3 years.

If you were to get the ESUs, the support for Windows Server 2012 will end in October 2026.
