KB5030269 Monthly Rollup for Windows Server 2012 R2

KB50302369 is the monthly rollup cumulative update for Windows Server 2012 R2 for the month of September 2023. It was released on 12th September as part of the ‘Patch Tuesday’ project.

Salient points

  • KB5030269 is a cumulative update that supersedes the KB5029312 monthly rollup update. KB5029312 was released in August 2023. You can read more about KB5029312 on this page.
  • KB5030269 also contains all the changes that are part of the security-only update KB5030287.
  • We recommend installing KB5030269 and preferring it over the KB5030287 security update for Windows Server 2012 R2. This is because monthly rollup updates are cumulative in nature and security-only updates are standalone updates.
  • A new Servicing Stack Update has also been released for Windows Server 2012 R2 on 12th September 2023. KB5030329 is the latest SSU for Windows Server 2012 R2. It needs to be deployed prior to installing KB5030269 on the server.
  • The issue with language packs continues to affect Windows Server 2012 R2. If you install a language pack after installing KB5030269, you will have to redeploy KB5030269. Microsoft is working on addressing the issue with language packs.
  • 13 security vulnerabilities have been disclosed for Windows Server 2012 R2 in September month’s security bulletin released by Microsoft. None of these vulnerabilities have a ‘CRITICAL’ severity.
  • There are no zero-day threats affecting Windows Server 2012 R2 as per September month’s security bulletin.

It may be pertinent to mention that Windows Server 2012 R2 goes EOS or End-of-support on 10th October 2023. Extended Security Updates will need to be bought to ensure you continue to get security updates for the server. ESU can be bought on an annual basis for a period of 3 years. This means you can extend support for Windows Server 2012 R2 from October 2023 to October 2026.
