Microsoft has released a support document titled “Release information for AI components” that details the AI components integrated into Windows 11, which can be installed through Windows Update or accessed via the Microsoft Update Catalog. These components are essential for enabling various AI models to operate locally on devices, and installations typically occur automatically on compatible PCs with 40+ TOPs of NPU. The size of Windows 11 Patch Tuesday updates has increased significantly, now ranging from 4-5GB, compared to previous updates that were under 800MB. Users can manage AI components through Settings > System > AI Components, although this page is empty for older PCs. The changelog includes individual components like the Settings Model, Image Search, Semantic Analysis, and Content Extraction, as well as lower-level elements such as Execution Provider. Updates for these AI models occur every few weeks, often without visible changes.
