Highlights for the Windows 11, version 25H2 update

• The Settings Agent now supports more languages, with expanded support for German, Portuguese, Spanish, Korean, Japanese, Hindi, Italian, and Chinese (Simplified).*
• This update expands the functionality of Cross‑Device Resume. You can continue activities from your Android phone on your PC based on the apps and services you use, including resuming Spotify playback, working in Word, Excel, or PowerPoint, or continuing a browsing session.
• This update improves MIDI on Windows with enhanced support for MIDI 1.0 and MIDI 2.0, including full WinMM and WinRT MIDI 1.0 support with built-in translation, shared MIDI ports across apps, custom port names, loopback and app-to-app MIDI, plus performance improvements and bug fixes—delivering a better experience for musicians.
• Narrator now gives you more control over how it announces on‑screen controls. You can choose which details are spoken and adjust their order to match how you navigate apps. These settings apply throughout the app to help reduce extra speech and make Narrator easier to follow.
• Windows Hello Enhanced Sign-in Security (ESS) now supports peripheral fingerprint sensors. This update extends this more secure sign-in option beyond devices with built-in fingerprint sensors to include desktops and other Windows 11 PCs, including Copilot+ PCs.

* Experiences for Copilot+ PCs only
