New Windows 11 build brings automatic PDF previews to File Explorer for Insiders

Microsoft has unveiled its latest Windows 11 Insider Experimental Preview builds, 26340.9233 (26H2) and 28120.2760 (26H1), introducing a suite of enhancements aimed at refining user experience and functionality. The 26H2 build notably incorporates automatic PDF preview support in File Explorer, alongside in-app purchase capabilities for elevated WinUI 3 applications within the Microsoft Store.

The 26H1 build mirrors these advancements while addressing a bug that rendered the mouse cursor invisible in certain applications. However, it comes with a caveat: a known compatibility issue may hinder the launch of PUBG: BATTLEGROUNDS for some users.

Modernized AutoPlay Experience

  • The AutoPlay dialog has received a significant overhaul, now built with WinUI for a more cohesive look and feel across Windows. This updated interface supports dark mode and enhances responsiveness to text scaling and display settings. Notifications for AutoPlay are conveniently docked in the notification center, ensuring easy access when devices like phones or cameras are connected.

Accessibility Enhancements

A Simpler Way to Open Apps Maximized

  • To activate this feature, navigate to Settings > Accessibility > Visual effects and enable Open apps maximized. This adjustment aims to provide a more consistent and full-screen workspace.

Managing Permissions for Desktop Apps

  • Windows Insiders can now manage camera, microphone, and location permissions for individual desktop applications, moving away from a single device-wide setting. This update enhances user control over privacy by allowing granular access management on an app-by-app basis.
  • Users can review permissions by navigating to Settings > Privacy & security > Camera, Microphone, or Location. Apps requesting access for the first time will prompt for permission, ensuring transparency in access requests.
