Download Windows 11 Preview Build 25158 With DNS Over TLS (DoT) And Notification Badging

There were no Insider updates last week, but this flight to the Dev channel makes up for it. Microsoft has now released Windows 11 Build 25158 which can be installed via Windows Update or using the standalone ISO installer.

Microsoft introduces some new features for the Windows 11 operating system along with a plethora of fixes and other improvements. There is a new notification badge that will be visible for the dynamic widgets in the taskbar, which will expand into more information upon clicking it. Moreover, DNS over TLS (DoT) testing is now also available for Windows DNS client query protection.

That said, it is expected that these features will make their way to the stable Windows 11 OS with version 23H2 , which will be released next year since the build for version 22H2 has already been declared (Build 22621).

Let us discuss these improvements in detail, and then continue to learn how to install this build.

New in Windows 11 Build 25158

Notification Badge for Widgets

Note: This feature is still rolling out to Insiders on the Dev channel gradually.

Users will now see a tiny notification badge on the Widgets in the taskbar which will look like something in the image below.

DNS over TLS (DoT)

Insiders can now test out the new feature for Windows 11; DNS over TLS. It is another protocol addition to the Windows operating system, similar to DNS over HTTPS (DoH).

To begin testing out this new feature, here are the steps to set it up:

  1. Navigate to the following:

    Settings app >> Network & internet >> Wi-Fi/Ethernet
  2. (Conditional) If you selected “Wi-Fi” in step 1, then go to Hardware Properties.

    Wi Fi Hardware Properties
    Wi-Fi Hardware Properties
  3. Now click Edit in front of “DNS Server Assignment.”

    Edit DNS Server Assignment settings
    Edit DNS Server Assignment settings
  4. In the popup, select Manual from the drop-down menu. Then trigger the slider below IPv4 into the On position. Under “Preferred DNS,” type in the IP address of the DoT server, then click Save.

    Enter DoT server address
    Enter DoT server address
  5. When done, close the Settings application and launch the Command prompt with elevated privileges.

  6. Now run the following cmdlets one after the other.

    netsh dns add global dot=yes
    netsh dns add encryption server=<the-ip-address-configured-as-the-DNS-resolver> dothost=: autoupgrade=yes
    ipconfig /flushdns

You will now have configured DNS over TLS on your PC. If you are still having trouble setting it up, refer to this TechCommunity post.

New Search Style on Taskbar

Note: This feature will only be available on selected devices.

Some chosen machines will now experience a new search style in the taskbar. This is an experiment by Microsoft, therefore, may be retracted in a future flight; depending on the user feedback.

With these new features, improvements, and fixes, there are also a few known issues we think you should know about before upgrading to this build.

Known Issues

    • Some games that use Easy Anti-Cheat may crash or cause your PC to bugcheck.
  • [File Explorer]

  • [Widgets]
    • The Notification badge number may appear misaligned on the taskbar.
    • 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 the top. Use the system menu (ALT + Spacebar) while the app has focus to move the app’s window further down.

Some of these issues have prolonged over the last few flights in the Dev channel, but some of them are new with this flight. Hopefully, Microsoft will address these in future releases.
