Microsoft is now rolling out Windows 11 build 25314 for devices enrolled in the Canary Channel of the Windows Insider Program. This is a minor update, but it includes various new features and improvements.

Build 25314 for Windows 11, according to the official changes, introduces changes for the new version of File Explorer, including key shortcuts for the context menu and file recommendations. Also, this flight ships with new Outlook support in Windows Narrator, and Local Security Authority (LSA) protection.

These are all the new features and improvements for the latest release of Windows 11 in the Canary Channel:

File Explorer

As part of the File Explorer improvements, Microsoft adds access key shortcuts into the XAML context menu to quickly execute a command. You can access the shortcuts view by selecting the file and pressing the “Menu” key on the keyboard or using the “Shift + F10” keyboard shortcut.

The “Home” page is also introducing the ability to suggest the relevant files under the new “Recommended” section. This is in addition to the “Recent” files that are still available on the same page.

According to the company, the feature is 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.

Local Security Authority (LSA)

In this flight, the operating system is introducing Local Security Authority (LSA) protection to help protect against theft of secrets and credentials used for login by preventing unauthorized code from running in the LSA process and by preventing dumping of process memory.

After an upgrade, the system will check for incompatibilities with the feature. If the operating system doesn’t detect any incompatibilities, it’ll automatically turn on “LSA Protection.” You can always check and change the enablement state of LSA protection on the Windows Security > Device Security > Core Isolation page.

Windows Narrator 

Windows 11 build 25314 also comes with changes for the Windows Narrator. For example, the feature will now retrieve updates to its Outlook support when Windows Narrator is started. Also, Narrator’s Outlook support is limited to U.S. English only. Other languages will be supported in a future flight.


Finally, starting with this release, Windows 11 is increasing security by disabling the Remote Mailslot Protocol by default. The legacy 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.

After this update, if an app tries to open a Remote Mailslot session over the SMB protocol, you may see one or more of the following errors, such as “3025 ERROR_REMOTE_MAILSLOTS_DEPRECATED” and tThe requested operation failed. Remote mailslots have been deprecated.”

If you need to temporarily enable Remote Mailslot, run the Set-SmbClientConfiguration -EnableMailslots $true PowerShell (admin) command.

Install build 25314

If you want to download and install the Windows 11 build 25314, enroll your device in the Canary Channel using the “Windows Insider Program” settings from the “Windows Update” section.

Once you enroll the computer in the program, you can download build 25314 from the “Windows Update” settings by clicking the Check for Updates button. However, you will need a device that meets the minimum system requirements to receive the update if you are new to the Windows Insider Program.

Update March 10, 2023: Microsoft is pushing the update KB5025135 as build 25314.1010 to testers, but the update does not include new. It is only designed to test the servicing pipeline.
