[Narrator]
Building on the math reading and navigation support introduced for Narrator in Build 26340.9354, we're expanding the experience with additional language and browser support. Narrator math reading now supports a total of six languages: English (United States), English (United Kingdom), Traditional Chinese, Finnish, German, and Spanish. You can choose your preferred language under Math reading settings in Narrator settings.
Math reading is also now available for supported web content in Microsoft Edge Stable version 153.0.4234.32 and later and Chrome Stable version 153.0.8010.18 and later, making it easier to read and explore equations across more of the places where students and professionals work.

[Taskbar]

Reminders for Windows Insiders in the Experimental channel
Updates are based on Windows 11, version 26H2 via an enablement package (Build 26340.9577).
Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time. We monitor feedback to see how they land before pushing them out to everyone in this 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, report those issues to us via Feedback Hub.
