Microsoft has released a new Windows 11 Build 23451 to the insiders in Dev channel. The new build brings a modernized Windows 11 File explorer details pane. It also includes UI changes and new features in Start Menu, Windows Spotlight, Widget and more.

Coming to details now, the new Windows 11 Build 23451 modernizes the details pane in File Explorer. The modern pane that can be invoked using (ALT + Shift + P) displays contextual information about selected files. The displayed information includes file thumbnail, share status and button, file activity, related files and e-mails, and other information.

Microsoft is also changing the aesthetics of Windows Spotlight and is testing two new behaviors. One of the behaviors includes a richer UI, full screen, and minimized experience. Both treatments will include 4K portrait images and the ability to learn more about each desktop image.

With the Windows 11 Build 23451, Microsoft is expanding availability of notification badging for Microsoft accounts on the Start menu. It also re-introduces websites in the Recommended section and claims to recommend more useful and personal websites based on browsing history instead of generally popular websites. Insiders can right-click on a website and choose to remove a website individually at any given time.

In other UI changes, Gallery in File Explorer has an updated new icon. The Build also introduces a new widget picker experience with an image. The new experience gives a visual preview of the widget before pinning. It allows users to jump directly to the picker from the provider app/service as well as a link to the widgets Store collection page where users can discover more apps with widgets. Microsoft has also rolled out animated icons for Widgets on the taskbar. The animation triggers when you hover or click on the Widgets taskbar entry-point or when a new widget announcement is displayed on your taskbar.

You can read the official changelog of Windows 11 Build 23451 provided by Microsoft below.

What’s new in Build 23451

Modernized Details Pane in File Explorer

We are introducing a modernized details pane in File Explorer (ALT + Shift + P) designed to help you easily access related content, stay up to date with file activity, and collaborate without even opening a file.

When a user selects a file in File Explorer and enables the pane, a modern pane will display contextual information about the file including file thumbnail, share status and button, file activity, related files and e-mails, and other information. To enable the pane, choose ‘Details pane’ in View menu and then toggle the pane with an easy-access button located on right side of the command bar. The View menu/toggle button in the command bar can similarly be used for accessing the preview pane. This modernized pane will replace the legacy details pane in File Explorer.

[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.

Improving Windows Spotlight

Starting with this build, we are trying out two different treatments for how Windows Spotlight looks. Both treatments will continue to share existing core Windows Spotlight features such as hovering over the icon on the desktop, right-clicking on the icon on the desktop, and double-clicking on the icon on the desktop. One treatment will include a richer UI, full screen, and minimized experience. Both treatments will include 4K portrait images and the ability to learn more about each desktop image. Insiders in the Dev Channel will see different treatments across their PCs so not everyone will see the same thing and the treatments will be shown in English only.

To enable Windows Spotlight on your PC today, right-click on your desktop and choose “Personalize” and then choose the new Spotlight theme. Alternatively, you can directly enable Windows Spotlight by going to Settings > Personalization > Background and choosing the option under the “Personalize your background” dropdown.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Windows Spotlight.

Narrator enhances interaction with Excel

Narrator now provides a more succinct and efficient reading experience while working in Microsoft Excel. Announcements are prioritized based on the information you need to skim a workbook and are customizable using convenient keyboard shortcuts. Review the Enhanced Narrator support in Excel documentation for further information.

To enable the enhanced announcements, you need to be on the latest Windows Insider and Office Insiders builds and start Narrator using the keyboard shortcut Control + Windows + Enter. The updated experience will be available through the Microsoft Store, so it may take a few minutes to be available on your PC. We look forward to you trying out our new changes and would love to hear your feedback and suggestions.

FEEDBACK: Please file feedback in Feedback Hub (Win + F) under Accessibility > Narrator.

New Widget: Facebook

Facebook is rolling out a preview version of their widget. To give it a try, download the Facebook app from the Microsoft Store or update to the latest version of the app. Then open the widgets board and navigate to the widgets picker by clicking the “+” button at the top-right of the board to pin your widget.

As you give this and other new widgets a try, please let us know what you think through the Widgets feedback link in the widgets picker. You should expect to see additional new widgets as more developers create and release widgets for their apps.

If you’re a Windows developer and interested in creating a widget, watch our tutorial video here.

Changes and Improvements

[Start menu]

  • We’re beginning to expand the roll out of notification badging for Microsoft accounts on the Start menu. A Microsoft account is what connects Windows to your Microsoft apps, backs up all of your data, helps you manage subscriptions, and where you can add extra security steps so you’re never locked out of your account. With this feature, we’re giving customers quick access to important account-related notifications. These notifications can be managed by going to Settings > Personalization > Start.

  • We continue to work on adding more valuable content to the Recommended section in the Start menu by re-introducing websites after trying this out with Insiders last fall. One improvement we’ve made is to recommend more useful and personal websites based on your browsing history instead of generally popular websites. Insiders can right-click on a website and choose to remove a website individually at any given time. Only some Insiders will see this experience and, if you do, please share your feedback. This feature will apply to users who have opted into sharing browsing data with Microsoft and have visited enough websites in Microsoft Edge or Google Chrome (with Continuous Import enabled). As a reminder, the settings for what is recommended on Start can be adjusted via Settings > Personalization > Start. Commercial customers can manage this experience via policy.

  • We are beginning to roll out animated icons for Widgets on the taskbar. The animation triggers when you hover or click on the Widgets taskbar entry-point or when a new widget announcement is displayed on your taskbar. Currently, only a few weather and finance icons are supported.
