What's new in build 19587

General changes and improvements

  • Based on feedback, when you have muted your volume, the volume will now not unmute when using the hardware keyboard volume keys until you raise the volume (or manually unmute).
  • We made a couple of improvements to Narrator and how it works with some of the controls in Windows:
    • Narrator now uses a more friendly string to describe the audio output in the Select playback device dropdown menu in the volume flyout.
    • Narrator now announces more information in the Add Bluetooth or other devices dialog in the Settings application when first opened.


  • We fixed an issue where the new icon next to Scan with Microsoft Defender in File Explorer's context menu didn't have a transparent background.
  • We fixed an issue that could result in Default Apps page in Settings crashing when you tried to change defaults.
  • We fixed an issue that could result in the search box being missing from certain apps.
  • We fixed an issue where some files couldn't be opened in win32 apps from File Explorer when the path length to the file was very long and parts of the path included East Asian characters.
  • We fixed an issue where thumbnails weren't being generated for pictures inside a Work Folder.
  • We fixed an issue where adding the Session column to the Users tab in Task Manager would result in not being able to expand the details for a particular user.
