Microsoft's latest beta update for Windows 11 24H2 Insiders—build 26120.3585 under KB5053644—introduces significant advancements in the Windows Search functionality, particularly for AMD and Intel-powered Copilot+ PCs. This update leverages local AI processing to deliver a more intuitive and efficient search experience.

Introduction of Local Semantic Search

The standout feature of this update is the integration of Local Semantic Search. This enhancement allows users to perform searches using natural language queries, eliminating the need to recall exact file names or specific keywords. For example:

  • Images: Searching for "bridge at sunset" will yield relevant photos without needing to know the file name.
  • Documents: Typing "Europe trip budget" will locate related documents based on their content.
  • Settings: Queries like "change my theme" will direct users to the appropriate settings page.

This semantic indexing, combined with traditional keyword indexing, enhances the search experience by understanding the context and content of files, making information retrieval faster and more intuitive. (blogs.windows.com)

AI-Powered Performance on Copilot+ PCs

The update harnesses the power of the 40+ TOPS Neural Processing Unit (NPU) integrated into Copilot+ PCs, enabling these search improvements to function even when offline. This local processing ensures that users can access their documents, photos, and settings without an internet connection. (blogs.windows.com)

Enhanced Cloud Photo Search

In addition to local search enhancements, the update improves the ability to find photos stored in the cloud. Users can now search for cloud-stored images using natural language descriptions, such as "European castles" or "summer picnics." This feature integrates cloud and local search results, providing a unified experience. Currently, this functionality is available for personal OneDrive accounts when connected to the internet.

  • File Explorer: Improved performance when extracting zipped files, especially those containing numerous small files.
  • User Interface: Updated the web sign-in icon on the lock screen for better alignment with other icons.
  • Settings: Fixed alignment issues in the navigation pane. (blogs.windows.com)

Conclusion

The Windows 11 24H2 Beta Update marks a significant advancement in user experience by integrating AI-driven semantic search capabilities. These enhancements, particularly for Copilot+ PCs, offer a more intuitive and efficient way to access and manage content, both locally and in the cloud.
