  • Microsoft launched builds for all insider channels.
  • On the Dev channel, insiders get Build 23430 with a lot of improvements here and there.
  • One of them is the ability to let Windows notifications work even if you’re in DND mode.

A lot of exciting pieces of news are coming to Windows insiders lately. Besides the Build 25336 on the Canary channel that somehow slows the booting time of the Terminal app, insiders on the Dev Channel are getting Build 23430.

As spotted by Windows enthusiast @PhantomOfEarth, the new XAML File Explorer, which was first teased back in February 2023, is getting somewhere.

Now, you can see a pane for details sitting comfortably on the right side of your File Explorer screen every time you click on a folder or a file. As you can see below, you’ll have features to see the insights of the file, such as when it was last modified, which user mentioned you last, etc. 

We first saw teasers of this feature back in January 2023 when the enthusiast showcased the first look of the new File Explorer, although, at that time, it was hiding inside the system and you’d need third-party tools to enable that. 

Good news for many? Not so fast. Although this feature would have an off-and-on toggle should it ever roll out, you could get a sneak peek of a file’s content without opening it. That means it won’t be good especially if you’re on a public computer.

What other fixes & improvements are coming in Windows 11 Build 23430?

Urgent or important notifications now show display a view notification button to view the content of the notification when using an app in full screen.

Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

Moreover, Redmond officials also said that the feature to bypass your notification system when on the Do Not Disturb (DND) mode is back. The feature was first teased back in the summer of 2022 in Windows 11 Build 22546 on the Dev channel, so it’s nice that we’re getting somewhere with this.

Urgent or important notifications that break through when do not disturb is turned on while using apps at full screen will now display a “view notification” button to view the content of the notification for privacy.

Here are other features that Microsoft brought to the table, as noted in their blog post. 


  • In the previous flight, we documented that Content Adaptive Brightness Control (CABC) works on desktop PCs – however, it does not. We have updated that blog post. Content Adaptive Brightness Control (CABC) also needs to be enabled by the OEM (the manufacturer of the device). As a result, this feature is not available on all laptop or 2-in-1 devices.


  • A limit of 20 most recent tabs has been introduced under Settings > Multitasking to show tabs in ALT + TAB and Snap Assist.


  • We are introducing a new setting under Settings > Privacy & security > For developers to enable end task when right-clicking an app on the taskbar. This setting is in Build 23430 but does not currently work when the feature is toggled on. It will be fixed in a future flight.



  • Fixed an underlying issue causing some Insiders to see an increase in explorer.exe crashes in the last 2 flights.


  • Fixed an issue where text input features like touch keyboard, voice typing, and emoji panel might not launch.
  • Fixed an issue where the buttons in the Pinyin IME’s settings flyout were hard to see when they had focus if a contrast theme was enabled.

[Task Manager]

  • Fixed an issue impacting Task Manager reliability.
  • The search box should no longer be cropped at the top when the window is maximized.


  • Fixed an issue where in Quick Settings, Narrator was reading out the previous page’s title instead of the active page’s.
  • After downloading voice access, information to help you get started with it should correctly open again now.
  • Fixed an issue where popups for voice access weren’t translated correctly.

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

[Search on the Taskbar]

  • There is an issue where some people may not see the search box on the taskbar and/or the settings to adjust the search box experience on the taskbar after updating to Build 23403. We are aware of the issue, and we are working on a fix.
  • If you have the Bing button in the search box on the taskbar and you restart your computer, you may see the daily rotating search highlight for some time before getting the Bing button back.

[File Explorer]

Insiders who have access keys in File Explorer:

  • Access keys will appear inconsistently if no button is pressed. Pressing a button will cause them to reappear.
  • [NEW] Shift + Right click on a file or folder is not opening “Show more options”.

Insiders will have issues with the following commands on recommended files in File Explorer:

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

[Live captions]

  • On ARM64 devices, enhanced speech recognition support installed through the Language & Region settings page will require restarting live captions if you switch languages in the live captions Caption language menu.
  • Certain languages shown on the Language & Region settings page will indicate speech recognition support (e.g., Korean) but don’t yet have support for live captions.
  • When adding a language through the Language & Region settings page, language feature installation progress may become hidden, and you may not see install completion of “Enhanced speech recognition” (required by Live Captions). (You can use the language’s “Language options” to monitor progress.) If this happens, there may be an unexpected delay before the live caption setup experience detects this and lets you continue.
  • Captioning performance may be degraded in non-English languages and missing out-of-language filtering in non-English (United States) languages which means that incorrect captions will be shown for speech not in the caption language.
