Microsoft halts the Windows 11 KB5079391 security update following widespread reports of installation cycle failures and error 0x80073712 on 24H2 and 25H2 versions
Microsoft has decided to stop the Windows 11 update process because users encounter major problems when they try to install the new version. Microsoft stopped the security update which protects Windows 11 from specific technical problems which users reported to exist in the system. The update identified as KB5079391 was originally intended to provide security enhancements and general improvements for the 24H2 and 25H2 versions of the operating system. The company stopped distribution on March 30 2026 because more users reported installation failures during the process.
The primary issue involves a specific error code recognized as 0x80073712 which appears during the final stages of the software application. The Windows 11 system cannot complete the update process because of this conflict which creates an installation cycle failure for all affected systems. Microsoft has chosen not to share any public details about the error's origin or which hardware systems are most likely to experience the issue.
Neowin investigative reporting shows that Microsoft has completely removed the KB5079391 package from the Windows Update delivery service. The company is currently implementing precautionary measures to eliminate possible system conflicts while their engineering teams work on resolving the core software stability issues. Users who have not yet attempted to download the patch will find that it is no longer available for their devices until a revised version is published.
Microsoft has not yet determined a specific date when the security update process will bring back its corrected version to public access. The sudden withdrawal of a monthly security release is relatively uncommon and highlights the severity of the installation failure discovered in this specific build. The company advises both enterprise and home users to maintain their existing system builds until the problem receives a solution because they are still gathering information about the initial launch failure.
The situation remains fluid as technical staff at Microsoft work to resolve the conflict between the update and the Windows 11 core files. The development team will provide additional updates after they determine what causes error 0x80073712 to occur. The development team works to ensure that future patch versions will not create stability issues for users throughout the world. The information in this report comes from Neowin journalists who first published the details and from official Windows Update system changes.
