New features and changes[edit | edit source]

Shell[edit | edit source]

The "New natural voices are available" dialog (pop up when launching Narrator) has been updated in order to align the design aesthetics of Windows 11.

Settings[edit | edit source]

The new section under Personalization > Text input for configuring the Copilot key on keyboard, previously implemented in build 27718, has been gradually rolled out. It can be activated manually by enabling the 52608608 velocity staging key.
The "Hand Off" feature and its settings under System > Hand Off, initially implemented in build 22635.4225, have been ported to this build. This feature is disabled by default, but can be activated manually by enabling the 49527529 velocity staging key.
