Windows 11 Insider Preview Build 27858 has been released to the Canary Channel. A new system tray icon for the emoji and more panel has been introduced, allowing users to access emojis, GIFs, and Kaomojis, with customization options available. Several fixes have been implemented, including resolving black screen issues during upgrades, enhancing accessibility in File Explorer, updating desktop icon logic, fixing voice typing initiation issues, resolving explorer.exe crashes related to snap layouts, addressing taskbar icon resizing problems in tablet mode, fixing night light functionality, and resolving MIDI device recognition issues. Known issues include potential problems with Windows Hello PIN and biometrics on new Copilot+ PCs and unresponsive pen input on certain devices. Insiders are reminded that builds in the Canary Channel are early development versions and may change. A clean installation is required to exit the Canary Channel, and a desktop watermark will be present in pre-release builds.
