TapTechNews attaches the following update contents this time:

Optimization and improvement (inviting some Dev channel users to test)

[Input]

Microsoft updated the Settings > Bluetooth and Devices > Mouse page, where users can turn off Enhanced mouse pointer precision and added an option to change the mouse scroll direction.

[VoiceAccess]

Improved the spelling and correction experience in VoiceAccess. The spelling experience now allows users to dictate characters at a faster rate and provides more editing flexibility in the experience through dictation commands (i.e., selection, deletion, and text navigation commands).

[Energy-saving tool]

For laptops using batteries, when the power saving mode is set to Always On, if the battery level reaches 20%, a notification will pop up asking the user to plug in the laptop power.

[Settings]

Microsoft has begun to roll out a new energy-saving recommendation in Settings > Power and Battery > Energy Recommendations, that is, to turn off HDR, so that PCs with HDR screens can save energy.

Fixes (inviting some Dev channel users to test)

[Settings]

Fixed the problem that the Let desktop applications access your location element under the Settings > Privacy and Security > Location page cannot be displayed but will flicker.

Known problems

[General]

Important: PCs running the Windows 11 24H2 Build 26100.xxxx version joining the Dev channel will see the words (repairversion), and users don't need to worry and can upgrade to the latest version normally.

Adding other languages or optional features may fail with the error 0x800f081f.

[Windows Sandbox]

The Windows Sandbox fails to start, showing the error 0x80370106.

[Task Manager]

Switching between different pages on the Task Manager may cause the Task Manager to crash.

This problem will cause the chart on the Performance page in the Task Manager not to display the correct color when using the dark mode again.

[Input]

The problem that text recommendations cannot be applied to physical keyboards.
