Taskbar & System Tray Enhancements
You can now activate the ‘never combined mode’ on the taskbar, providing a more streamlined user interface. This feature can be enabled for multiple monitors as well.
Narrator Improvements
Significant improvements have been made to the Narrator, including a change in the default verbosity level and the addition of a Traditional Chinese dictionary for detailed reading.
“We have made the following improvements for Narrator: Changed default verbosity level from 2 to 3 which will now announce ‘Immediate Context Name and Type’.”
These updates are sure to provide a more efficient and user-friendly experience for all Windows 11 users.
What’s Important to Know?
Insiders previously on Build 22624 will automatically move to Build 22631 via an enablement package. This package increments the build number for the update, making it easier to differentiate from devices with the update features turned off by default.
Insiders in the group with new features turned off by default can check for updates and choose to install the update for features rolling out.
With these exciting new features and improvements, Windows 11 continues to evolve, providing a more efficient and user-friendly experience for all.
