Improvements 7 changes

Shared audio

    The main volume controls in Quick Settings and on-device or keyboard controls can still adjust both listeners at once.
  • A taskbar indicator shows when audio is being shared and provides a shortcut to sharing settings.2
    Clicking the indicator opens sharing settings to adjust volume or stop sharing.
  • Shared audio support includes Samsung Galaxy Buds 4 and Buds 4 Pro, Sony WF‑1000XM6, and Xbox Wireless Headset.3

Taskbar

Gradual rollout 2 items
  • The rollout of improved animations when the taskbar is set to autohide is temporarily paused.4
  • Taskbar components load more reliably in Safe Mode.4

New features 3 changes

Batch files and CMD scripts

Gradual rollout

For: Administrators and Application Control for Business policy authors

  • Administrators can enable a more secure mode that prevents batch files from changing while they run.6
    Set LockBatchFilesWhenInUse (DWORD, 0 or 1) under HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor. Application Control for Business policy authors can also enable the mode through the LockBatchFilesWhenInUse application manifest control.

Narrator

Gradual rollout

For: Narrator users

  • A new keyboard command reads the contents of an app’s status bar, such as the word count in Word or the sum or average of selected cells in Excel.7

Paint

For: Insiders receiving the Paint app update

  • You can rotate shapes, text, and active selections to any angle, or enter an angle using Custom rotate.8
