Changes and improvements gradually being rolled out
[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 — true plug-and-play 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 models like the 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.

[Accessibility]
New accessibility setting: Screen tint- We're introducing screen tint, a new accessibility setting that applies a color overlay across your entire display, softening its intensity so it's easier on your eyes throughout the day. If bright, saturated screens leave you with tired or sensitive eyes by the end of a long session, screen tint can help.

Screenshot showing UI for screen tint in Accessibility, with color presets and a strength slider. - To get started, open Settings > Accessibility (or press Win + U) and look for screen tint under the Vision section. From there you can:
- Pick from six preset colors or choose a custom color of your own.
- Adjust the tint strength slider from a subtle wash to full intensity.
- Night light warms your display to reduce blue light that can interfere with sleep. Screen tint reduces overall screen intensity to ease eye fatigue and light sensitivity during the day. They tackle different problems and you can use both at the same time, one working on warmth and the other on intensity.
- Note that turning on screen tint will disable color filters, and vice versa. If you currently rely on color filters, you may need to keep screen tint turned off.
[Magnifier]
- Touch bars for panning in Magnifier are now off by default. Hiding them gives you a cleaner, less distracting magnified view on touchscreen devices.
- If you use a touch screen device and prefer on-screen bars for navigating your magnified view, you can turn them back on anytime in Settings > Accessibility > Magnifier.

[Windows Ready Print]
- Last month, we introduced a change where new printer installations use IPP by default when supported to simplify setup and improve reliability (see our third-party driver deprecation timeline: End of Servicing Plan for Third-Party Printer Drivers on Windows). This month, we're adding a new toggle in Settings > Bluetooth & devices > Printers & scanners > Default install printers using Windows Ready Print to give you control over this behavior.

- This experience is part of our modern print platform, now called Windows Ready Print, designed to deliver a more consistent, reliable, and simplified printing experience.
[Voice Access]
Voice Isolation in Voice Access- We're introducing Voice Isolation, a new option in Voice Access that helps it focus on your voice, even when others are speaking nearby. Whether you're in a shared office, an open floor plan, or at home with family around, Voice Isolation filters out other voices and background noise so Voice Access can better understand you. All processing happens privately on your device.
- Getting started
Voice Access now offers three speech recognition modes under Voice Access settings > Improve speech recognition:- Voice Isolation — Filters out other speakers and background noise (one-time voice setup required).
- Remove background noise only — Filters out non-speech sounds like typing or door slams. No additional setup needed.
- No filtering — Default microphone input with no additional processing.

Reminders for Windows Insiders in the Experimental channel
- Updates are based on Windows 11, version 25H2 via an enablement package (Build 26300.8497).
- Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
- For Windows Insiders who want to be the first to try new features, see the available list of features to toggle on at the Feature flags page under Settings > Windows Update > Windows Insider Program.
- 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 may never get released as we try out different concepts and get feedback. Features may 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 may 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.
- Check out Flight Hub for a complete look at what build is in which Insider channel.
