It's another week, which means it's time for another Windows 11 Insider Preview build for those in the Dev Channel. Today's build is 22478 and finally introduces the new Fluent-style emoji that the company first announced a couple of months ago. These new emoji align themselves with the rest of Windows 11's new, modern design.

In addition to the new emoji, today's build includes a bunch of new fixes and under the hood improvements to test. Here's what's new:

  • 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.
  • 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.
  • We have begun testing Update Stack Packages that deliver update improvements outside of major OS updates such as new builds.

Microsoft is also releasing new wallpapers to mark the 7th anniversary of the Windows Insider Program. You can check out all the wallpapers here.

There's also a handful of new fixes as well:

  • Keyboard focus will no longer get lost if you press ESC after opening the user profile flyout in Start.
  • Updated the prompt text when pinning something from a UWP app to Start, so it now says simply "Do you want to pin this to Start?".
  • Addressed an issue that was causing Notification Center to get stuck in a state in recent builds where it would stop launching.
  • The plus icon for adding a new Desktop will now display properly when hovering over the Task View icon in the Taskbar when using Arabic and Hebrew languages.
  • After bringing up an app's jump list from the Taskbar, right clicking on the app name should now show the correct icon for Pin to Start (a pin icon).
  • Left and right clicking Taskbar at the same time should no longer crash explorer.exe.
  • Fixed an issue where the command bar was doing unnecessary calculations when navigating to folders, causing an unexpected increase in performance. This is also believed to be the root cause of performance issues when using drag to select files, as well as using the arrow keys to navigate in certain folders.
  • The "Show hidden items" option should no longer get out of sync when multiple File Explorer windows are open.
  • The recent searches flyout when hovering over the search icon in the Taskbar should no longer immediately dismiss on invocation if an admin window is in focus.
  • Setting focus to the search box in File Explorer shouldn't make the touch keyboard invoke and immediately dismiss now when using a tablet with the Taskbar set to auto-hide.
  • Fixed an issue causing the handwriting panel to not insert text when using it to write Chinese.
  • Mitigated a memory leak that could occur in ctfmon, causing unexpected resource usage over time.
  • Addressed an issue for a small number of users that was causing TextInputHost.exe crashes when setting focus on any text field.
  • for example if you connected an additional audio endpoint while the Sound page in Settings was open.
  • Improved performance of loading the themes displayed in Personalization Settings.
  • If a non-admin user changes their display language in Language Settings, we'll no longer show the clickable sign-out button there as it was popping a UAC dialog and causing confusion.
  • The Windows Update entry at the top of the System page in Settings should no longer be misaligned with the other options (when shown) in languages like German.
  • The Braille options in Settings for Narrator users should now be in sync with the actual state of the Braille input/output mode.
  • Made a change to help address an issue where "Media streaming options" in the Network and Sharing Center would unexpectedly revert to default settings after an upgrade.
  • Improved Quick Settings launch reliability. This change should also help address the issue causing the window to not fully render (just a thin rectangle).
  • Addressed an issue where if you clicked on the media controls area in Quick Settings, it wasn't bringing the app displayed to the foreground in certain cases.
  • Fixed an issue where the colors for items in Quick Settings could get stuck and not reflect the proper color for that state, particularly when using a contrast theme.
  • Updated the Quick Settings page for managing audio endpoints from "Volume" to "Sound output".
  • Opening the page for managing audio endpoints in Quick Settings should no longer cause a brief cut in audio playback when multiple devices are listed.
  • Mitigated an issue related to using ALT + Tab very quickly that could make explorer.exe crash.
  • Holding down ALT and pressing F4 after pressing ALT + Tab will no longer crash explorer.exe.
  • When using the Arabic or Hebrew display languages, dragging an app window to a different Desktop should show the thumbnail moving in the correct direction now.
  • Fixed a casing issue that was causing LP.cab files to be unexpectedly removed in certain cases, which could lead you your display language changing until you added the desired display language back in Settings.
  • Addressed an issue that was causing some users to see a bugcheck with error "KERNEL_SECURITY_CHECK_ERROR".
  • Mitigated an issue that was causing the SysMain service to use an unexpected amount of power in recent builds.
  • If the display order is missing in BCD settings that should no longer cause an upgrade failure.
  • Fixed an issue that was causing captions to draw at the wrong offset in certain apps.
  • Mitigated an issue that was causing crashes related to audiosrv.dll.
  • If going through OOBE with an Arabic or Hebrew display language, the volume and accessibility buttons should display on the correct side of the screen now.

As always, you can check out the Windows Blog for the complete changelog, including a list of known issues.
