Microsoft has released Windows 11 Insider Preview Build 22478 to Windows insiders in the dev channel.





Announcing Windows 11 Insider Preview Build 22478

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 22478 to the Dev Channel. 

What’s new in Build 22478

New Fluent Emoji

Back in July,  the Microsoft Design Team announced refreshed and new Fluent-designed emoji that would roll out across all of Microsoft 365 – including Windows. We are excited to be giving Windows Insiders a “first look” at how our new emoji design will look in Windows 11 starting with today’s Dev Channel build.Emoji have become part of the way we communicate. Extending our expression by providing humor, feelings, and fun. You will notice we have redesigned all the emoji and introduced some nostalgia for our fans by making the standard paperclip emoji our beloved Clippy! As part of this rollout, we’re adding support for Unicode emoji up to  Emoji 13.1 which includes new emoji such as face in the clouds, heart on fire, space with spiral eyes plus many more!

To check out the new emoji, just open up the emoji panel (WIN + . )!

After previewing these with Windows Insiders, we plan to bring these new emoji to everyone on Windows 11 via a future servicing update.

Changes and Improvements

  • The updated version of the Korean IME, which began rolling out with  Build 22454, is now available to everyone in the Dev Channel.
  • When your laptop is closed, it’s now possible to login to your PC using Facial Recognition (Windows Hello) on a connected external monitor if it has a camera attached that supports it.
  • We’ve made a change to the underlying indexer platform to help improve overall reliability and database size, which should help reduce disk space usage on the system – particularly in cases where users had very large Outlook mailboxes.
  • Scrolling your mouse wheel on the volume icon in the Taskbar will now change the current volume level.
  • Made some small adjustments to the dialog when adding a new language in Settings to make it look a little more modern, including rounding the corners.
