Windows 11 Insider Beta (26H1) Preview Build 28020.2539

Release date: 20 July 2026

Changes and improvements gradually being rolled out

  • This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.

[Narrator]

  • Braille displays now connect instantly with Narrator.
  • We're making refreshable braille displays easier to use in Windows. Narrator now supports displays that use the HID standard, an open industry standard for braille displays. If your display supports HID, simply connect it via USB and start reading with no additional setup required.
  • For Bluetooth, pair your HID braille display in Settings > Bluetooth & devices just like any other accessory, and you can work wirelessly without being tethered to your PC.
  • Compatible HID displays include Orbit Reader 20, Orbit Slate 340, Freedom Scientific Focus 40, and APH Mantis Q40.
  • HID braille displays now work during the initial Windows setup experience (OOBE) over USB, meaning users who are deaf-blind can set up their PC independently right from the first screen.
  • You can customize braille input and output options anytime in Settings > Accessibility > Narrator > Braille.

[Voice Access]

  • Voice Access now supports Portuguese (Portugal), Portuguese (Brazil), and Korean (South Korea).

[Settings]

  • The Bluetooth quick settings page is now navigable using gamepad input.
  • Fixed an issue causing the Graphics page in Settings to crash for Insiders after the latest updates.

[Sounds]

  • Improved system sounds when using Windows in dark mode.

Reminders for Windows Insiders in the Beta (26H1) channel

  • The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.

  • Features and experiences included in these builds might never get released as we try out different concepts and get feedback. Features might change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they're ready.

  • Some features in active development we preview with Windows Insiders might not be fully localized, and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
