Microsoft has introduced an upgraded search experience for Windows 11, specifically targeting Copilot+ PCs, as part of the Windows Insider Dev Channel update (Build 26120.2992). This new feature leverages semantic indexing alongside traditional indexing to enable natural language search capabilities, allowing users to find files, photos, and settings without needing to recall specific file names or keywords. For example, users can search for images by describing them (e.g., "bridge at sunset") or locate documents by their content (e.g., "Europe trip budget").

The enhanced search functionality is powered by the Neural Processing Unit (NPU) embedded in Copilot+ PCs, which handles over 40 trillion operations per second (TOPS). This allows the feature to work offline and process complex queries locally. Initially, the improved search is limited to files stored locally in indexed locations, with plans to expand support to cloud storage providers like OneDrive in future updates. Supported file formats include common document types (.pdf, .docx) and image formats (.jpg, .png).

Users can customize indexed locations via Settings > Privacy & Security > Searching Windows and enable "Enhanced" indexing for broader coverage. The feature currently supports six languages: Chinese, English, French, German, Japanese, and Spanish.

Rollout and Availability

The feature is being gradually rolled out to Windows Insiders using Snapdragon-powered Copilot+ PCs. Support for AMD and Intel Copilot+ PCs will follow. The update is exclusive to these high-end devices due to their reliance on NPU hardware.

Microsoft’s Strategy and Significance

This update underscores Microsoft's push toward integrating AI into its operating system to improve productivity and user experience. It aligns with the company's broader strategy of promoting AI-powered hardware like Copilot+ PCs. These devices are marketed as faster and more efficient than older systems, offering features such as all-day battery life and advanced AI capabilities.

By limiting this feature to Copilot+ PCs, Microsoft aims to differentiate these devices from standard Windows PCs and encourage upgrades ahead of Windows 10's end-of-support in October 2025.

Industry Reactions

While the AI-driven search functionality has been praised for its potential to simplify file discovery, some critics have noted its exclusivity as a drawback for users without Copilot+ hardware. Additionally, early testers have reported minor issues such as occasional unresponsiveness in File Explorer searches.

In summary, Microsoft's improved Windows Search represents a significant step forward in leveraging AI for practical applications on desktop operating systems. However, its limited availability may restrict its immediate impact on the broader user base.
