Microsoft has announced the release of the optional non-security preview update KB5074105 for Windows 11, applicable to versions 25H2 and 24H2. This update, part of the January 2026 "C-week" schedule, is focused on enhancing functionality, optimizing performance, and improving reliability, without addressing security vulnerabilities.
The update is cumulative, meaning it integrates previous fixes while introducing changes to the operating system's servicing stack and AI-driven components. Notably, a critical notification is included regarding the expiration of Windows Secure Boot certificates , which are set to expire starting June 2026. Administrators and users should ensure timely updates to avoid boot security issues.
Microsoft recommends reviewing guidance on Certificate Authority (CA) updates to prevent operational disruptions.
To reduce administrative complexity, Microsoft has simplified the title format for Windows updates. The updated naming convention omits redundant technical elements, such as platform architecture, while retaining essential identifiers like the date prefix, KB number, and build version. This change aims to improve readability in log files and deployment tools such as Windows Server Update Services (WSUS) and Microsoft Configuration Manager.
Microsoft has announced the release of the optional non-security preview update KB5074105 for Windows 11, applicable to versions 25H2 and 24H2.
The KB5074105 update enhances the underlying models for Copilot+ PC experiences and standard Windows 11 AI features through a phased rollout. The updated component versions are as follows:
Image Search: 1.2601.1268.0 Content Extraction: 1.2601.1268.0 Semantic Analysis: 1.2601.1268.0 Settings Model: 1.2601.1268.0
This cumulative update includes the Servicing Stack Update (SSU) KB5074104, raising the servicing stack version to 26100.7704. The SSU is crucial for installing Windows updates and ensuring the robustness of the update engine. Microsoft combines the latest SSU with the Latest Cumulative Update (LCU) to prevent version mismatches during deployment. Once applied, the SSU portion cannot be uninstalled.
IT administrators can deploy this update via Windows Update for Business, the Microsoft Update Catalog, or WSUS. To remove the LCU portion for troubleshooting, the standard wusa.exe /uninstall switch will not work due to the combined SSU payload. Instead, the Deployment Image Servicing and Management (DISM) tool should be used with the /Remove-Package option. The exact LCU package name can be obtained using DISM /online /get-packages in an elevated command prompt. No known issues have been reported for this release.
