Microsoft has released the first Windows 11 build for the new Canary channel. Build 25314 shares many of the changes that the new dev channel build of 23403 includes, Microsoft say they are not always going to blog about the changes to the builds on the Canary Channel but this time they have detailed the changes:

Access Keys in File Explorer

Microsoft have added access key shortcuts to the context menu in File Explorer. You can try this by pressing the menu key when in File Explorer:

File Recommendations in File Explorer

File recommendation are going to show up in File Explorer

This feature (as pictured below) will be available to users signed into Windows with an Azure Active Directory (AAD) account. Files that are recommended will be cloud files associated with that account, either owned by the user, or shared with the user.

Here are the other changes:

Introducing LSA Protection Enablement on Upgrade

Local Security Authority (LSA) protection helps protect against theft of secrets and credentials used for logon by preventing unauthorized code from running in the LSA process and by preventing dumping of process memory.

Narrator will now retrieve updates to its Outlook support when Narrator is started. You can learn more about the work we did for Outlook in Chapter 5 of the Narrator User Guide. We have not added any additional functionality to our Outlook support, but this work will allow updates to the Outlook experience to be made through the Microsoft Store.

Changes and Improvements


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:

  • “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 $true
