multi msu

The multi MSU tag on WindowsForum.com covers discussions about Microsoft's multi-MSU delivery model for Windows updates, where cumulative updates are combined with discrete component updates. A key example is the Windows 11 KB5079466 update (OS Build 28000.1719), which uses multi MSU to deliver traditional servicing fixes alongside on-device AI component updates for Copilot+ features. This approach is relevant for both consumer power users and enterprise IT teams managing Windows 11 deployments. The tag focuses on the technical aspects of how multiple MSU packages are bundled and applied, including servicing stack updates and AI-related components.
