New Features in Windows 11 Insider Preview 10.0.26120.3073
1. Enhanced Windows Search with Cloud Integration
One of the standout features of this build is the improvement to Windows Search through enhanced cloud integration. This update allows users to locate photos stored in their cloud drives using natural language descriptions. Instead of relying on exact filenames, users can search for images by describing their contents.
For example, typing phrases like “summer vacation in Paris” or “birthday party with balloons” in File Explorer’s search box will bring up relevant images from the user’s OneDrive or other cloud storage services. This feature is currently available for Windows Insiders using Snapdragon-powered Copilot+ PCs, with plans to extend it to AMD and Intel-powered Copilot+ PCs in future updates.
2. Optional Dev Channel Updates for Beta Insiders
Microsoft has introduced a new flexibility feature in this update by offering Dev Channel updates to Beta Channel Insiders. These updates are based on Windows 11 version 24H2 and are entirely optional, allowing Beta users to install them at their discretion. This move ensures that Beta users have access to advanced features while still maintaining stability.
3. Performance and UI Enhancements
Windows 11 Build 26120.3073 comes with multiple performance optimizations and UI refinements. Microsoft has focused on the following:
- Improved Start Menu Responsiveness: Users will experience faster Start Menu interactions with reduced lag.
