Dev Channel Insiders were a tad disappointed they didn’t get their own update right after the Release Preview Channel, so Microsoft sought to correct that.

Thus, the wait is finally over, and Windows Insiders can finally download a new Dev build from the official Microsoft sources.

As you might have expected, it contains quite a large number of new features and improvements and we’re about to get right into it.

What should I know about build 25247?

With that in mind, know that there are some long-anticipated changes, seconds for the tray clock and Task Manager enhancements, and several unexpected additions, such as website recommendations on the Start menu.

When talking about Windows 11 build 25247, we have to also mention the new jump list support on the taskbar feature for the Microsoft Store.

Another interesting change is the fact that Windows Studio effects can now be accessed directly from Quick Settings on the taskbar, for devices that have a supported Neural Processing Unit (NPU).

It is now quicker and easier to enable and configure camera effects, such as Background Blur, Eye Contact, automatic framing, and audio effects like Voice Focus.

Access Studio effects from Quick Settings.

Microsoft is also rolling out Energy Recommendations, so you can go ahead and review, then apply these recommendations to improve the energy efficiency of your PC and reduce your carbon footprint.

Process filtering for the Task Manager is a top feature request from our users that wanted to be able to filter/search for processes.

Know that you can filter either using the binary name, PID, or publisher name, as the filter algorithm matches the context keyword with all possible matches and displays them on the current page.

And, the filter is also applied as you switch between pages so you can also use the keyboard shortcut Alt + F to focus on the filter box.

The new search box at the top of Task Manager allows you to filter Binary name, PID or Publisher name.

Also, the Task Manager now also supports themes for in-app dialogs, just in case you didn’t know about this yet.

Furthermore, all dialog except for Run new task and Properties dialog now support themes and will adhere to either app specific theme or Windows theme.

The tech giant also mentioned adding the ability to use your preferred theme in Task Manager regardless of the active theme in Windows.

Let’s not forget that, when copying text with search potential, Windows will pop up an inline light dismissible UI that suggests searching this text in Microsoft Edge.

When you select the search action, a new Edge tab is launched to search the copied text. Please keep in mind that this feature will initially be available for Insiders in the U.S. only.

Another important change is the fact that the Settings app supports new visuals on your Accounts page to provide a visual overview of your cloud storage usage across Microsoft products.

These new visuals include a consolidated cloud storage bar that shows your storage usage for each product and notifies you if you’re running low on storage.

Let’s also take a closer look at the rest of the changelog and discover what else Microsoft planned for this new Windows 11 Dev build.

Changes and improvements

[General]

  • Earlier this week, Microsoft released an optional .NET update (2022-11 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows Version Next for x64 (KB5020992)) to Windows Insiders in the Dev Channel designed to test delivery of .NET improvements in the future. This .NET update does not include anything new and will be available under Settings > Windows Update > Advanced Options > Optional Updates If you run into any issues finding or installing this update, please submit feedback via Feedback Hub.

[Start menu]

  • Working on adding more valuable content to the Recommended section in Start and are excited to introduce a new content type: websites. For the first phase, Microsoft recommends common websites based on your region or browsing history to help you easily get back to the websites you care about. This can be controlled by right-clicking on a website and choosing to remove that website individually or to stop showing all recommended websites entirely. Only some Insiders will see this experience and, if you do, please share your feedback.

[Taskbar & System Tray]

  • As a response to user feedback, Microsoft is introducing the capability to show seconds in the clock on the system tray. This feature can be enabled by toggling the option listed under Settings > Personalization > Taskbar in the Taskbar behavior section. You can also right-click on taskbar to quickly get to taskbar settings. Beginning to roll this change out so not all Windows Insiders will see this change right away, but we hope to make it available to everyone soon.

[Search on the Taskbar]

  • Made performance improvements that will allow more files and content on your PC to show up as results in the Windows search box. We look forward to hearing your feedback on whether you notice an improvement with your file results within Windows.

[Input]

  • Switched the touch keyboard icon option under Settings > Personalization > Taskbarfrom being a toggle to now being a dropdown where you can select Never, Always, or When no keyboard attached.
  • Including two new keyboard layouts in this flight. These keyboards implement the two new French keyboard layout standards (AZERTY and BÉPO). The new layouts are designed to allow the user to type all the required characters of the French language. They also include support for all the Latin-based languages of the European Union as well as Greek letters and a large variety of scientific, mathematical, and financial symbols. To enable one of these layouts, go to Settings > Time & language > Language & region and select Language options under the ellipsis for the language you would like to use this keyboard with. On the Options page, select “Add a keyboard” and look for the new keyboard layouts “French (Standard, AZERTY)” or “French (Standard, BÉPO)”. The previous AZERTY layout now displays as (Legacy, AZERTY).
  • Made improvements to Emoji search for Japanese and Simplified Chinese by handling Kana/Kanji and Pinyin properly in the emoji panel.
