Announcing Windows 11 Insider Preview Build 27723 (Canary Channel)

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27723 to the Canary Channel. 

Changes and Improvements

[General]

• [REMINDER] Insider Preview Build Expiration: The expiration date for Insider Preview builds flighted to the Canary Channel has been updated to 9/15/2025 starting with  Build 27695. Please make sure you are updated to the latest build in the Canary Channel.

[Search on the Taskbar]

• We are beginning to roll out the ability to share local files directly from within the search results shown in the search box on the taskbar.

New option to share a local file highlighted in a red box in the search results from the search box on the taskbar.

[Voice Access]

• We are making improvements for the spelling and corrections experience in voice access. You can now use the experience for the entire voice access session. The spelling experience will now enable you to dictate the characters at a faster speed and offer more editing flexibility inside the experience with dictation commands, namely selection, deletion and text navigation commands.

[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.

[Settings]

• The detach virtual hard disk (VHD/VHDx) button we added under Settings > System > Storage > Disks & Volumes introduced with  Build 27686 has temporarily been disabled starting with  Build 27718. We’re working to re-enable this change in a future flight soon.
