Announcing Windows 11 Insider Preview Build 23475

Announcing Windows 11 Insider Preview Build 23475

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 23475 to the Dev Channel.

TL;DR: This build includes a handful of new features we’re beginning to roll out to Windows Insiders in the Dev Channel including a modernized File Explorer Home and address bar, Dynamic Lighting, and support for Emoji 15. As part of introducing these new features, we’ve also added some new known issues. We’re also releasing a new Microsoft Store update. Check out all the details in the below blog post!

What’s new in Build 23475

Modernized File Explorer Home and Address Bar

Now that File Explorer is powered by Windows App SDK, we are introducing a modernized File Explorer Home powered by WinUI. Recommended files for users signed into Windows with an Azure Active Directory (AAD) account will be displayed as a carousel and support file thumbnails which is coming soon. Quick Access folders (available by default for users signed into Windows with a Microsoft account), Favorites, and Recent also bring in an updated experience with WinUI.

We are also introducing a modernized address bar and search box to File Explorer. The new address bar intelligently recognizes local vs. cloud folders with built-in status. For OneDrive users, you’ll notice the address bar now contains your OneDrive sync status and quota flyout.

[We are beginning to roll this out, so the experience isn’t available to all Insiders in the Dev Channel just yet as we plan to monitor feedback and see how it lands before pushing it out to everyone.] 

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Files, Folders, and Online Storage > File Explorer.

Dynamic Lighting

Dynamic Lighting provides Windows users and developers with native control of Lighting Devices implementing the open HID LampArray standard. By adopting an open standard, and by working with our OEM and ODM partners,  Microsoft seeks to improve the RGB device and software ecosystem for users by increasing interoperability of devices and apps. Included are APIs for Windows apps to control devices from the background and foreground, as well as a page in Windows Settings for users to customize how their devices behave.

Several device manufacturers including Acer, ASUS, HP, HyperX, Logitech, Razer, and Twinkly have partnered with Microsoft on Dynamic Lighting.

As of the publication of this post, a list of current, in-market compatible devices is below. Review the Dynamic Lighting Hardware MS Learn page for a more current list of compatible in-market devices. The latest firmware should be used with these devices. We are aware of several issues with wireless device connections so please use a wired connection with a compatible device to a PC, if possible, for the time being. And check out the known issues below in this post for other issues that may impact this experience.

Changes and Improvements

[General]

• The feature where we now detect if the user is interacting with toasts or not and provide a suggestion to turn the toast banners off for such apps that began rolling out with Build 23466 is now available to all Windows Insiders in the Dev Channel.

[Emoji]

• The Unicode Emoji 15 is beginning to roll out to Windows Insiders in the Dev Channel. Users will now be able to see, search for and insert new emoji from the emoji panel. Here are a few of our Emoji 15 designs which include more hearts, animals and one new smiley face.

Fixes

[Taskbar & System Tray]

• Fixed an issue where the taskbar may not have shown the correct apps when using multiple desktops.

[Search on the Taskbar]

• Fixed the issue where Narrator customers were unable to navigate down the left side panel of the search flyout.

[Start menu]

• Fixed an issue where when using a Japanese display language, sometimes apps with names written in kanji would all show at the bottom of the all apps list, rather than displayed alongside hiragana and katakana app names.

[Notifications]

• Fixed an issue where certain notifications were leading to an explorer.exe crash.

[Input]

• We’re rolling out the fix for an issue where Korean touch keyboard sometimes finalizes characters unexpectedly in the search flyout on the taskbar.

[Backup and Restore]

• Backups of a PC that was set up using a restore will now show up in subsequent restores.
• Restore of solid color desktop backgrounds are now supported.

[Other]

• Fixed issues that were causing voice access commands for moving settings sliders and selecting things on the taskbar to fail.

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.

Known issues

[Dev Drive]

• On a reboot, additional filters beyond AV might be attached to your Dev Drive. To check what filters are attached, please run ‘fsutil devdrv query :’ in Windows Terminal. If you are seeing more than your AV filters, you can run ‘fsutil volume dismount :’ and then ‘fsutil devdrv query :’. After those steps, you should only see your AV filters.
• There might be variable performance on different hardware. If you notice slower performance on your machine, please file feedback!

[Search on the Taskbar]

• Navigating the search flyout on the taskbar with the keyboard arrow keys will not work as expected.
• Text scaling may not work in the search flyout.

[File Explorer]

• Insiders may experience a File Explorer crash when dragging the scroll bar or attempting to close the window during an extended file-loading process.
• Thumbnail loading performance in Gallery for dehydrated cloud files and memory usage in large collections are known issues we are focused on improving. Please capture Performance traces in Feedback Hub for any performance-related issues. Rebuilding your Indexer can help if thumbnails are missing for cloud files; Search for “Indexing Options” and look in Advanced settings to find the rebuild tool.

Insiders who have the modernized File Explorer Home that began rolling out with Build 23475:

• [NEW] File Type icons are displayed in place of file thumbnails for Recommended section (applicable to Enterprise users).
• [NEW] Insiders signed in with an AAD account and try to navigate the Recommended section on File Explorer Home with the tab key on the keyboard may experience an explorer.exe crash.
• [NEW] When navigating from another group to the Recommended section using a keyboard, focus does not appear on the group header or files appropriately.
• [NEW] Files display file extensions with the Show file extensions setting disabled.
• [NEW] Sync status icons for files backing up to a storage provider are not reliably displayed.
• [NEW] In case of an authentication error on File Explorer Home, the ‘Please Sign-in’ button appears but clicking on it does not pop-up the authentication dialog.

Insiders who have the modernized File Explorer address bar that began rolling out with Build 23475:

• [NEW] Windows Insiders may notice missing craftmanship polish with the modernized address bar and search box. The team greatly appreciates the use of Feedback Hub to help call out important details to address.
• [NEW] Users might experience lost keyboard focus and missing keyboard shortcuts. The team implemented improved tabbing with keyboard shortcuts that will be available soon.

Insiders will have issues with the following commands on recommended files in File Explorer that began rolling out with Build 23403:

• Clicking on the Share command will currently bring up the Windows share sheet (non-OneDrive).

[Notifications]

• The copy button for quickly copying two-factor authentication (2FA) codes in notification toasts (first introduced in Build 23403) is currently not working in this build. A fix is coming in a future flight.

[Dynamic Lighting]

• [NEW] On first boot after installing this build and connecting a device, the “Use Dynamic Lighting on my devices” toggle is off in Settings. Device LEDs may not turn on automatically. Turning this toggle on in the all-device Settings page and in the per-device page(s) should turn on your device’s LEDs. If this doesn’t work, try restarting your Windows PC again.
• [NEW] All-device settings changes are not propagating to per-device Settings.
• [NEW] Device icons are missing from the device cards in Settings.
• [NEW] Switching user accounts can turn off device LEDs.

Microsoft Store Update

Windows Insiders in the Canary and Dev Channels running version 2305.1401.x.x of the Microsoft Store and higher will see the following improvements rolling out:

• Install free apps and games from search results: The ability to install free apps and games from search results which began rolling out to Insiders in the Canary and Dev Channel at the end of March is rolling out to more Insiders starting today.

• New designs for game and movie cards: Browsing the Microsoft Store is more delightful than ever with our new designs for game and movie cards. The cards give more room for artwork, adding more color to your experience and making it easier for you to spot your next favorite product.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Microsoft Store.

For developers

You can download the latest Windows Insider SDK at aka.ms/windowsinsidersdk.

SDK NuGet packages are now also flighting at NuGet Gallery | WindowsSDK which include:

• .NET TFM packages for use in .NET apps as described at aka.ms/windowsinsidersdk
• C++ packages for Win32 headers and libs per architecture
• BuildTools package when you just need tools like MakeAppx.exe, MakePri.exe, and SignTool.exe

These NuGet packages provide more granular access to the SDK and better integration in CI/CD pipelines.

SDK flights are now published for both the Canary and Dev Channels, so be sure to choose the right version for your Insider Channel.

Remember to use adaptive code when targeting new APIs to make sure your app runs on all customer machines, particularly when building against the Dev Channel SDK. Feature detection is recommended over OS version checks, as OS version checks are unreliable and will not work as expected in all cases.

About the Dev Channel

REMINDER: The Dev Channel has been rebooted. Windows Insiders who were in the Dev Channel on 25000 series builds are being moved to the new Canary Channel. Going forward, the Dev Channel will receive 23000 series builds. Insiders who were moved to the Canary Channel and want to move back to the Dev Channel can follow these instructions to do a clean installation of Windows 11 and then re-join the Dev Channel to receive 23000 series builds.

The Dev Channel receives builds that represent long lead work from our engineers with features and experiences that may never get released as we try out different concepts and get feedback. It is important to remember that the builds we release to the Dev Channel should not be seen as matched to any specific release of Windows and the features included may change over time, be removed, or replaced in Insider builds or may never be released beyond Windows Insiders to general customers. For more information, please read this blog post about how we plan to use the Dev Channel to incubate new ideas, work on long lead items, and control the states of individual features.

In some cases, features and experiences may go out to the Canary Channel first before going out to the Dev Channel however the Dev Channel will provide better platform stability. As we get closer to shipping, some features and experiences will also make their way to the Beta Channel when they are ready.

The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
