Windows 11 Insider Preview Build 27938 for the Canary Channel introduces new AI actions in File Explorer, a bigger clock with seconds option in notification center, and privacy controls for app-based AI usage.
What’s New in Build 27938
AI Actions in File Explorer

Microsoft continues its push toward native AI integration by bringing AI actions to File Explorer in Build 27938. Users can right-click eligible files (.jpg, .jpeg, .png) to access new AI actions directly from the context menu:
-
Bing Visual Search: Conduct web searches using images rather than text; identify products, landmarks, plants, and more for instant answers.
-
Blur Background: Quickly highlight subjects while blurring backgrounds using the Photos app, customizable with intensity levels and brush tool edits.
-
Erase Objects: Remove unwanted elements in photos via Generative Erase—perfect for cleaning up distracting objects.
-
Remove Background: Use Paint for seamless one-click cutouts, isolating subjects from the rest of the image.
These AI actions keep users productive, bringing robust Copilot and AI functionality without leaving File Explorer or opening separate apps.
Bigger Clock with Seconds in Notification Center

A popular request from the Windows 10 community returns—Windows 11 now lets users see a bigger clock with seconds directly above the date and calendar in notification center. Enable it in: Settings > Time & language > Date & time > Show time in Notification Center.

This feature is rolling out gradually and aims to improve time-tracking and accessibility for power users.
Privacy Controls for Generative AI

A new privacy page is added: Settings > Privacy & security > Text and image generation. Here, users can review which third-party applications recently accessed Windows-provided AI models and selectively control their permissions, putting users in control of AI-powered experiences on their devices.
