New features and changes

Windows Copilot

Windows Copilot, which was partially implemented in build 23481, is fully functional in this build. It is currently a web-based app running inside Microsoft Edge-powered container, and will appear as a sidebar docked to the right side of the screen alongside the desktop or open windows when invoked by clicking the Copilot button on the taskbar or pressing ⊞ Win+C.

The latest version of Microsoft Edge (version 115.0.1901.150 or higher) is required for Windows Copilot to work. The support of third-party plugins, previously announced during the Microsoft Build 2023 conference, has not yet been implemented. It's also only available to a subset of users, but can be activated by enabling the 41655236, 42105254, 44774629, 44776738 and 44850061 velocity staging keys.

Settings

A new Home page has been added and rolled out to a subset of users. This page includes seven interactive cards that represent various device and account related settings, listed as follows:

• Recommended settings: Provides entry points for recent and commonly used settings based on user's specific usage patterns.
• Cloud storage: Provides the overview of Microsoft OneDrive's cloud storage.
• Account recovery: Prompts users to add a additional recovery email address.
• Personalization: Provides the basic settings under the Personalization page, including themes and color mode selections.
• Microsoft 365: Provides the status and benefits for Microsoft 365 subscription.
• Xbox: Provides the status for Xbox Game Pass subscription.
• Bluetooth devices: Provides the quick access to Bluetooth device management.

The Home page is only available on the Home and Pro SKUs, and can be activated by enabling the 42058313, 42058345, 42977909, 44049197 and 44124573 velocity staging keys.

File Explorer

The performance of archive functionality during compression has been improved.

Shell

• The redesigned Sound output page in Quick Settings, initially implemented in build 25281, has been backported to this build.
• The smart suggestions feature in snap layouts has been implemented. This feature is only available to a subset to users, but can be activated manually by enabling the 42500395 velocity staging key with the variant parameter set to 1 or 2.
• A new API for invoking a pop-up confirmation notification for pinning app to the taskbar has been implemented.
• When switching between virtual desktops by pressing the key combination ⊞ Win+Ctrl+← or →, a pop-up showing the name of the current desktop will appear at the bottom of the screen.
• The support of JPEG XR high dynamic range (HDR) wallpaper on HDR displays has been implemented. This feature is disabled by default, but can be activated manually by enabling the 41135193 velocity staging key.

Backup

When restoring the system using Windows Backup, the pins for restored desktop apps will appear on the taskbar and Start menu. Clicking on the app pins will download and install apps from Microsoft Store automatically (for UWP apps) or direct to the web to download the installer (for Win32 apps.)

The following Narrator natural voices have been added:

• Japanese: Microsoft Nanami (Female), Microsoft Keita (Male)
