Announcing Windows 11 Insider Preview Build 25309

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 25309 to the Dev Channel.

TL;DR

• With this build, we’re beginning to roll out a new enhanced volume mixer in Quick Settings. We’re also re-introducing an update for the touch keyboard settings, some changes to File Explorer, graphics, and input. And we have some voice access improvements.
• As always, this build also includes a good set of fixes too.

What’s new

New volume mixer experience in Quick Settings

We’re introducing a new enhanced volume mixer into Quick Settings! The updated audio quick settings experience brings a modern volume mixer that allows for quick customization of audio on a per-app basis, with additional control to swap devices on the fly. We’ve also added a new keyboard shortcut (WIN + CTRL + V) to bring you directly to the volume mixer for faster control of the experience. With this change, you can now tailor your audio experience better with more control and fewer clicks to better manage your favorite apps.

In addition, we’ve made it easier for users to enable their Windows Sonic experience with a quick access list of installed spatial sound technology. You can visit the Microsoft Store to find additional spatial sound technology to choose from such as Dolby and DTS.

[We are beginning to roll this feature out, so it 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 Desktop Environment > Quick Settings.

Updated Touch Keyboard Settings

After making some fixes, we are re-introducing the new touch keyboard setting we originally introduced with Build 25188 (and disabled with Build 25217) that replaces the “Show the touch keyboard when there’s no keyboard attached” checkbox under Settings > Time & language > Typing > Touch keyboard with a new dropdown menu with 3 options to control whether tapping an edit control should launch the touch keyboard:

• “Never” suppresses the touch keyboard even when no hardware keyboard is attached.
• “When no keyboard attached” will show the touch keyboard only when the device is used as a tablet without the hardware keyboard.
• “Always” will show the touch keyboard even when the hardware keyboard is attached.

[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 Input and Language > Touch keyboard.

Auto Color Management (ACM) Expansion

Back in October, we launched Auto Color Management (hardware accelerated system level color management) on select qualifying and specially provisioned SDR displays. Now, Insiders in the Dev Channel will be able to turn ACM on for their SDR displays and have all colors across all Windows apps, whether or not they are color-managed, appear accurately and consistently on every supported display.

To turn ACM on, go to Settings > Display > Advanced display, select correct display and turn on Automatically manage color for apps.

Note: ACM enablement has the following requirements:

• WDDM driver version 3.0 or greater
• Supported GPU:
  • AMD:
    • AMD RX 400 Series or later
    • AMD Ryzen processors with Radeon Graphics
  • Intel
    • Integrated: Intel 12th Gen (Alder Lake) or later
    • Discrete: Intel DG1 or later
  • NVIDIA:
    • NVIDIA GTX 10xx or later (Pascal+)
  • There are no hard requirements on the display or connection – ACM can provide benefits even on 8-bit sRGB panels. However, we strongly recommend ACM devices to have panels with a wider-than-sRGB gamut, and optionally 10-bits per color channel or greater.

[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 Display and Graphics > Windows HD Color.

Voice access improvements

Redesigned in-app command help page: We have completely renovated the in-app command help page in voice access to make it simpler to use and comprehend. The search bar allows users to quickly find commands and the different categories provide further guidance. Every command now has a description and examples of its variations, making it easier to understand and use.

You can access the command help page from Help > View all commands on the voice access bar or use the voice command “what can I say”.

Please note that the redesigned in-app help page in voice access may not include all commands and the supplementary information may be inaccurate. We plan to update this in future builds. If you want an exhaustive list of Voice Access commands and extra information about them, we recommend you refer Use voice access to control your PC & author text with your voice – Microsoft Support.

Voice access is available in English dialects: We have extended voice access to support other English dialects such as English -UK, English – India, English – New Zealand, English – Canada, English – Australia.

When voice access is turned on for the first time, you will be prompted to download a speech model to enable on-device recognition of voice data. In case voice access does not find a speech model matching your display language, you can still choose to proceed ahead to use voice access in English – US.

You can always switch to a different language by navigating to Settings > Language on the voice access bar.

New text selection & editing commands: We have added some more useful commands to make text selection and editing easier with voice access (see original blog post below).

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Accessibility > Voice Access.

Changes and Improvements

[General]

• Starting with Build 25290, we started a new exploration of badging on the Start menu with two new treatments that some Insiders in the Dev Channel will see. Starting today, we’re trying out different text variants within these treatments. If you see one of these treatments, give us feedback on what you think. As a reminder, it is normal for us to try out different concepts in the Dev Channel to get feedback.
• We’re trying out a more personalized second-chance out of box experience (SCOOBE) with a small subset of Windows Insiders in the Dev Channel.

[Search on the Taskbar]

• The search box on taskbar will be lighter when Windows is set to a custom color mode. Specifically, when the Windows 11 mode is set to dark, and the app mode is set to light under Settings > Personalization > Colors you will see a lighter search box on taskbar.

[File Explorer]

• Windows Insiders will begin noticing a “pizza” icon on the command bar in File Explorer. This icon denotes that an Insider is previewing the Windows App SDK version of File Explorer. Functionality in File Explorer remains unchanged, it just switches from using WinUI 2 to using WinUI 3.

[Snap layouts]

• After pausing this with Build 25300, we are un-pausing this with this build – we are trying out different treatments for snap layouts with Windows Insiders in the Dev Channel. We are investigating ways to improve the discoverability and usage of the snap layouts such as decreasing the hover time required to invoke the flyout when you mouse over the maximum/restore button in an app’s title bar. In addition to a few other tweaks, you’ll notice some treatments will also pull in the icon of the app window you are working in and adding a descriptive title. If you see one of these treatments, give us feedback on what you think. As a reminder, it is normal for us to try out different concepts in the Dev Channel to get feedback.

[Windows Spotlight]

• Starting today, we are disabling the different treatments we’ve been trying out for Windows Spotlight that began with Build 25281 due to an issue impacting the experience Insiders will have on these treatments. We plan to re-introduce an updated Windows Spotlight experience for Insiders in a future flight based on the feedback from Insiders from using these different treatments. As part of disabling these treatments, Insiders may need to go to Settings > Personalization and re-enable Windows Spotlight.

[Input]

• We have updated the Simplified Chinese handwriting recognition engine to be faster and more accurate as well as supported characters defined in GB18030-2022. Currently you can write characters in GB18030-2022 Level 2 and some of characters in GB18030-2022 Level 1 in the handwriting panel or directly into the text field when it’s supported. Please try it and let us know what you think.

[Widgets]

• We are beginning to roll out theme-aware icons for Widgets on the taskbar so that based on the user’s Windows theme (dark or light), the Widgets icons will display a theme-aware icon that will have a higher contrast ratio which will make information on the taskbar clearer for users, particularly for those with low-sight.

[Settings]

• Settings > Power & Battery has been updated to include settings for choosing what happens when interacting with your PC’s physical power controls.

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 aka.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 integration in CI/CD pipelines.

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.
