What’s new

Notification badging for Widgets

We’re beginning to roll out even more dynamic Widgets content to your taskbar with notification badging for Widgets. Below is an example of a notification badge for Widgets.

Notification badging for Widgets on the taskbar.

When you open the Widgets board a banner will appear at the top of the board providing more information on what triggered the notification badge.

[We are beginning to roll those features out, so the experience isn’t available to all Insiders 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 Desktop Environment  > Widgets.

Changes and Improvements

[General]

Thank you to all the Insiders who gave us feedback on our first exploration of lightweight interactive content on the Windows desktop! Starting with this week’s flight, we are concluding this initial exploration, so if you received this experience, it will be removed on your next reboot.
As described in our in our blog post here, Windows Insiders who use the Dev Channel may get to try out new ideas, longer lead features, and experiences that are intended to help validate concepts. Starting with this build, some devices will receive different visual treatments for search on the taskbar. We are excited to learn from your feedback on this, so please use the Feedback Hub to provide feedback if you receive this experiment. NOTE: A reboot is required after updating to this build to trigger this experience but please note that not all Windows Insiders will have this experience enabled even after reboot.

[DNS over TLS]

DNS over TLS testing is now available for Windows DNS client query protection. DoT is another protocol in addition to DNS over HTTPS (DoH) which is already supported in Windows 11 and Windows Server 2022. For setup instructions, see this Windows Networking blog post. The setup requires command line use and is recommended for advanced networking users.

[Input]

The Nyala font has been updated to support syllables for the Gurage language orthography from the Ethiopic Extended-B Unicode range. Also revised and replaced Ethiopic kerning to fix gaps and errors in earlier implementation improving the overall texture of text in Ethiopic languages.

Fixes

[General]

Fixed an issue causing some Insiders to experience bugchecks with error message KMODE_EXCEPTION_NOT_HANDLED in NetAdapterCx.sys in recent flights.
Fixed an issue which was leading some PCs hanging at black screen when resuming from a low power state in recent flights.
Fixed an issue believed to generally be impacting performance across Windows shell experiences in the last few flights.
Fixed an issue where the Mica material and Acrylic blur effect was rendering incorrectly in OS surfaces like the Start menu, Notification Center and other areas sometimes in recent flights.

[File Explorer]

Fixed an issue where closing command bar flyouts could in some rare cases crash explorer.exe.
Fixed an issue which could lead to explorer.exe crashing when navigating through File Explorer with OneDrive enabled.
CTRL + F4 should work to close the current tab now.
Opening a zipped folder in a new tab should no longer have a blank tab name.
If focus is on the tab row, CTRL + W will no longer unexpectedly close two tabs instead of just the tab in focus.
Fixed an issue where CTRL + Tab wouldn’t cycle in the correct order after rearranging tabs.
We made some adjustments so when using “Show full path in title”, the folder name is always visible in the tab at the top of File Explorer.

[Taskbar]

Fixed an underlying issue which could lead to pinned app icons getting stuck on the taskbar after uninstalling the app in recent flights.
Fixed a high hitting explorer.exe crash in the last few flights related to loading Widgets.

[Start]

Start shouldn’t crash anymore when using CTRL + Shift + Right Arrow to move a pinned app into a folder that’s the last item in Start.
Fixed a crash some Insiders were experiencing when opening Start.
Narrator will now read the prompt that opens when trying to uninstall an app from Start correctly.

[Search]

Fixed an issue when using IRowsetPriorititization where setting the scope priority for a query rowset did not properly alter the indexing speed of the rowset, resulting in slower indexing overall.
Searching for “power mode” should now return an entry for power modes in Settings.

[Settings]

Updated the “System” entry under Network & Internet > Advanced network settings > Data Usage, to now be called “System and Windows Update” to help make it more clear.
Made another fix to address an issue where the “Listen to this device” option for audio devices would stop working after a reboot.
Fixed a crash some Insiders were seeing when navigating Bluetooth & Devices > Printers & Scanners.
Fixed an issue where the “Allow Bluetooth devices to find this PC” checkbox under Bluetooth & Devices > Devices > More Bluetooth Settings wouldn’t display the correct state sometimes.
Fixed an issue which was causing Quick Settings to crash for ARM64 PCs when attempting to use the Cast section to cast to certain devices.
Fixed an issue that could cause the eye icon beside the Wi-Fi password box in Quick Settings to disappear after its first use.

[Input]

Fixed a crash in textinputhost.exe initialization which was happening in some cases in recent flights.
Fixed an issue where the “Sync across your devices” option under Settings > System > Clipboard wouldn’t stay enabled.
Updated the Times New Roman font family so it includes U+061D / ARABIC END OF TEXT MARK.

[Windowing]

We made some improvements to help with the performance of opening Task View.

[Narrator]

Made a fix so the two-finger triple tap touch gesture to dismiss context menus with Narrator is working correctly again.

[Task Manager]

Fixed an issue where some services were being unexpectedly grouped under Microsoft Edge when they weren’t actually child processes.

[Other]

Fixed an issue which would lead to losing network connectivity after turning on mobile hotspot.
Addressed an issue that could result in the mobile hotspot button getting unexpectedly stuck in a greyed out state in certain cases.
Fixed an underlying issue which was leading to Your Phone crashes in certain cases.
Fixed an underlying issue where Microsoft Defender Application Guard windows weren’t visible in the last few flights.
Fixed a crash that could happen when using suggested actions.
Fixed an underlying issue when recording game clips using the Xbox Game Bar, which could lead to the resulting saved video not displaying correctly when viewed later on an iOS device.
Made some improvements to help address an issue resulting in apps in the Microsoft Store failing to download with error 0x80080204.
Addressed an underlying issue leading to Microsoft Store app remediation failures with error 0x803FB004.
Did some work to address an issue where the print dialog wasn’t launching centered in the application (for example, in Notepad).

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

[General]

[NEW] We’re investigating reports that SQL Server Management Studio is failing to launch for some Insiders.
Some games that use Easy Anti-Cheat may crash or cause your PC to bugcheck.

[File Explorer]

The up arrow is misaligned in File Explorer tabs. This will be fixed in a future update.
We’re working on a fix to address reports that launching File Explorer in certain ways when using dark mode (for example, from the command line) is showing the body of File Explorer unexpectedly in light mode.

[Widgets]

[NEW] Notification badge number may appear misaligned on the taskbar.
[NEW] In some cases, the notification banner for some badging will not appear in the widgets board.
We’re working on the fix for an issue causing Widgets preferences (temperature units and pinned widgets) to unexpectedly get reset to default.

[Live captions]

Certain apps in full screen (e.g., video players) prevent live captions from being visible.
Certain apps positioned near the top of the screen and closed before live captions is run will re-launch behind the live captions window positioned at top. Use the system menu (ALT + Spacebar) while the app has focus to move the app’s window further down.

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 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 integrate in CI/CD pipelines.

Changes in this version:

ColorProfileGetDeviceCapabilities is now present in the SDK and works for callers that wish to know if a device supports different kinds of display color profiles.

About the Dev Channel

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.

These aren’t always stable builds, and sometimes you will see issues that block key activities or require workarounds. It is important to make sure you read the known issues listed in our blog posts as we document many of these issues with each flight.

Build numbers are higher in the Dev Channel than the Windows 11 preview builds in the Beta and Release Preview Channels. You will not be able to switch from the Dev Channel to the Beta or Release Preview Channels without doing a clean install back to the released version of Windows 11 currently.

ALSO: Because the Dev and Beta Channels represent parallel development paths from our engineers, there may be cases where features and experiences show up in the Beta Channel first.

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