Windows 11 407 Published by

Microsoft has released Windows 11 Insider Preview Build 23403 to Windows insiders on the dev channel as well as Build 25314 to the new Canary channel.





Announcing Windows 11 Insider Preview Build 23403

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 23403 to the Dev Channel. 

Changes and Improvements

[General]

  • Users will now see a copy button for quickly copying two-factor authentication (2FA) codes in notification toasts from apps installed on the PC or from phones linked to the PC. We make a best effort to determine if a notification toast has an authentication code but please send us feedback if we got it wrong or if we failed to detect the code in a notification toast. This change is beginning to roll out, so not all Insiders in the Dev Channel will see it right away.

[Taskbar & System Tray]

  • We have added a glanceable VPN status into the system tray when connected to  a recognized VPN profile. The VPN icon, a small shield, will be overlayed in over the active network connection. Currently, the overlayed VPN icon does not use your system accent color but will do so in a future build.

[Search on the Taskbar]

  • The search box on taskbar will be lighter when Windows is set to a custom color mode. Specifically, when the Windows 11 mode is set to dark, and the app mode is set to light under Settings > Personalization > Colors you will see a lighter search box on taskbar.

[Input]

  • We have updated the Simplified Chinese handwriting recognition engine to be faster and more accurate as well as supported characters defined in GB18030-2022. Currently you can write characters in GB18030-2022 Level 2 and some of characters in GB18030-2022 Level 1 in the handwriting panel or directly into the text field when it’s supported. Please try it and let us know what you think.

[Settings]

  • Right-clicking on a Win32 app in Start, or searching for the app, and choosing “Uninstall” will now take you to the Settings to uninstall the app.

Fixes

[Search on the Taskbar]

  • Fixed rendering issues when using the touch keyboard with the search box on taskbar.
  • Fixed an issue when double clicking the search highlight glyph in the search box makes it disappear.
  • Fixed an issue where the search box would randomly disappear.
  • Fixed an issue where the search icon flips incorrectly for right-to-left (RTL) languages.
  • Fixed on issue where you might have seen some text flicker in the search box when you click into it.
  • Fixed an issue where the search box might disappear on one monitor if you are using multiple monitors.
  • Made some accessibility fixes to the settings for search under Settings > Personalization > Taskbar.

[File Explorer]

  • Fixed an underlying issue believed to be the cause of File Explorer unexpectedly jumping into the foreground sometimes.

NOTE: Some fixes noted here in Insider Preview builds from the Dev Channel may make their way into the servicing updates for the released version of Windows 11.

Announcing Windows 11 Insider Preview Build 25314

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 25314 to the Canary Channel. 

Changes and Improvements

[General]

To increase security in Windows 11, starting with this build and later we are disabling the  Remote Mailslot Protocol by default. The legacy Remote Mailslot Protocol is a simple, unreliable, insecure, and unidirectional inter-process communications protocol between a client and server and was introduced in Windows NT 3.1 and will be deprecated in a future Windows release. If an application attempts to open a Remote Mailslot session over the SMB protocol, you may see one or more of the following errors:

  • 3025 ERROR_REMOTE_MAILSLOTS_DEPRECATED
  • “The requested operation failed. Remote mailslots have been deprecated.”

If your application still uses Remote Mailslot, contact your vendor about updating their software. The legacy Remote Mailslot is not secure and should not be used under any circumstances. If you need to temporarily enable Remote Mailslot, run the following command in an elevated PowerShell console:

PS C:\> Set-SmbClientConfiguration -EnableMailslots $tr
