- Windows 11 build 28020.2539 (Beta) is now available for version 26H1.
- Narrator now supports HID braille displays, allowing compatible devices to work without extra drivers and during Windows setup.
- The update improves Settings reliability, Bluetooth gamepad navigation, Graphics settings stability, and dark mode system sounds.
Microsoft has released Windows 11 Insider Preview build 28020.2539 for version 26H1 via the Beta channel in the Windows Insider Program. These flights introduce improvements for existing features.
According to the official notes (Beta), Windows 11 build 28020.2539 introduces some undisclosed general improvements and fixes to improve the overall experience.
As part of the changes for build 28020.2539, Microsoft is making braille displays easier to use by adding support for devices that follow the HID (Human Interface Device) standard.
Users can now connect compatible refreshable braille displays through USB and start using Narrator without installing additional drivers or completing extra setup steps.
For wireless use, HID-compatible braille displays can be paired through Settings > Bluetooth & devices, allowing users to work without being connected to a computer by cable.
Supported devices include Orbit Reader 20, Orbit Slate 340, Freedom Scientific Focus 40, and APH Mantis Q40. HID braille displays also now work during the initial Windows setup experience (OOBE) over USB, helping users who are deaf-blind configure a new device independently from the first screen.
Other fixes
In addition, Windows 11 builds 28020.2539 and 28120.2387 also push several fixes and improvements.
- Voice Access: Added support for Portuguese (Portugal), Portuguese (Brazil), and Korean (South Korea) languages.
- Settings: Improved Bluetooth quick settings navigation with gamepad input support and fixed a crash affecting the Graphics settings page.
- Sounds: Improved system sound behavior when using Windows in dark mode.
