New features and changes[edit | edit source]

Widgets[edit | edit source]

The settings page has been redesigned, along with a new option to toggle Microsoft Start feeds. This change is only rolled out to a subset of users, but can be enabled by toggling on the 45393399 velocity staging key.

Shell[edit | edit source]

A new "Energy saver" button has been added under Quick Settings. It's designed to extend battery life by reducing system performance and certain background processes, and can be configured to run automatically as soon as the device's battery level reaches a predetermined threshold.
The Refresh button under the Wi-Fi section in Quick Settings, initially implemented in build 25997, is fully functional and has been publicly rolled out.
The performance of the VPN connections list under Quick Settings has been improved.
The overall performance and responsiveness of Quick Settings have been improved.
The original taskbar implementation in explorer.exe can now be disabled by toggling on the 42537950 velocity staging key. This breaks third party utilities that re-enable the Windows 10-style taskbar.

Settings[edit | edit source]

The account-related notifications for Microsoft accounts have been added to the Home page.
A new "Energy saver" section and a "Always use energy saver" toggle switch have been added under the System > Power page. The toggle switch behaves in the same way as the aforementioned "Energy saver" button in Quick Settings.
The colored backplates from all app icons under Apps > Installed apps and System > Notifications have been removed. This change was partially implemented in build 25977.

Miscellaneous[edit | edit source]

The ReFS file system has been updated to version 3.12.

Bugfixes[edit | edit source]

Fixed an issue that was causing installation of some apps, including Phone Link, to fail with error 0x87AF0813 in build 25997.
Fixed an underlying issue where the Microsoft Store was getting stuck when trying to check for and install app updates.
Fixed an issue that was causing the Settings app to crash when navigating to Bluetooth & devices > Touchpad.
Fixed an issue that was causing File Explorer to crash on launch when using a non-default regional sorting option.
