Windows 11 Insider Preview Build 22635.4300 (KB5044386) is now available to Windows Insiders in the Beta Channel. The build includes updates to the Start menu, fonts, security, and fixes. The new simplified Chinese typeface (Simsun-ExtG) supports Unicode Extensions G, H, and I, as well as the requested Biangbiang noodles character (U+30EDD). Windows Search executes IFilters in Less Privileged App Containers (LPAC), which restricts access to sensitive system components and data.

The update also addresses a high-impact explorer.exe catastrophe and a problem with the navigation pane elements. Unexpected spacing between items in the Start menu, all apps list, and crashes with live captions are among the known issues. Additionally, a Clock app update is ready for Windows Insiders, which includes countdown and timer widgets. Feedback can be submitted using the Feedback Hub.

Announcing Windows 11 Insider Preview Build 22635.4300 (Beta Channel)

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 22635.4300 (KB5044386) to the Beta Channel.

Changes and Improvements gradually being rolled out to the Beta Channel with toggle on*

[Start menu]

• “All apps” is now just “All” on the Start menu. This change began rolling out with  Build 22635.4291 earlier this week.

[Fonts]

• There is a new simplified Chinese font (Simsun-ExtG) with 9,753 ideographs supporting Unicode Extensions  G,  H and  I. Included is the highly requested character for Biangbiang noodles. This character U+30EDD is said to be the most complicated Chinese character, as you can see in the image below. We are aware that some applications may not be able to display these new extension characters yet.
  • Unicode range G 30000-3134A (4,939 chars)
  • Unicode range H 31350-323AF (4,192 chars)
  • Unicode range I 2EBF0-2EE5D (622 chars)

Biangbiang character Unicode 30EDD.

[Security]

• Windows Search runs IFilters in the Less Privileged App Containers (LPAC). LPAC are like app containers, but they deny even more permissions by default. The intent is that a process running in a LPAC has access only to the resources needed by it. This model helps to minimize the potential damage that can be caused by a compromised process by limiting its access to sensitive system components and data.

Fixes gradually being rolled out to the Beta Channel with toggle on*

[General]

• Fixed a high hitting explorer.exe crash impacting Insiders while using your PC in the last few Beta Builds.

[File Explorer]

• Fixed an issue which was causing the items in the navigation pane to become very spread out (with unexpected padding between each item) for some people.

Known issues

[Start menu]

• After installing this build, you may find there is an unexpected amount of spacing between items in the Start menu all apps list.

[Live captions]

• After installing this build, live captions will crash if you try to use it.

New Clock widgets: Countdown and Timer

We are rolling out a Clock app update to Windows Insiders across all Insider Channels that includes two new clock widgets: countdown and timer. Make sure you have the latest version of the Clock app update from the Microsoft Store (version 11.2408.9.0 and higher). After you open the widgets board, you can open the widgets picker by clicking the “+” button in the top right corner where you would be able to add these widgets to your board.
