Written By

published August 9, 2023

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 25926 to the Canary Channel.

REMINDER: As builds released to the Canary Channel are “hot off the presses,” we will offer limited documentation for builds flighted to the Canary Channel including documenting only the most significant and highly impactful known issues. Please note that we will not publish a blog post for every flight – only when new features are available in a build.

What’s new in Build 25926

New features from the Dev Channel

This build includes new features from the Dev Channel, such improvements for Windows Ink, improved screen casting experience, local file sharing improvements (was available in last week’s Canary Channel flight), and more.

Changes and Improvements

[Taskbar & System Tray]

Notifications will now show as a bell in the system tray and when new notifications come through, the bell will colorize based on your system accent color. When there are no notifications and the clock is visible, the bell will be empty. Notification counts are no longer shown.

[Graphics]

Starting with Build 25921, we have added options for tuning intensity and color boost to the color filters via Settings > Accessibility > Color Filters. Please note there is an issue in which the labels for the sliders are missing. The first slider is for “Intensity” and the second slider is for “Color Boost”. The labels will appear as expected in a future flight.

Fixes for known issues

We fixed the issue causing devices with mobile broadband connectivity to not be able connect to a wireless network due to an issue in which the APN configuration may get lost on upgrade with Build 25921.

Snipping Tool Update

We are beginning to roll out an update to Snipping Tool (version 11.2306.43.0 and higher) to Windows Insiders in the Canary and Dev Channels. This update introduces new buttons to edit in Paint for screenshots and edit in Clipchamp for screen recordings.

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.

SDK flights are now published for both the Canary and Dev Channels, so be sure to choose the right version for your Insider Channel.

Remember to use adaptive code when targeting new APIs to make sure your app runs on all customer machines, particularly when building against the Dev Channel SDK. Feature detection is recommended over OS version checks, as OS version checks are unreliable and will not work as expected in all cases.

About the Canary Channel

The Canary Channel is the place to preview platform changes that require longer-lead time before getting released to customers. Some examples of this include major changes to the Windows kernel, new APIs, etc. Builds that we release to the Canary Channel should not be seen as matched to any specific release of Windows and some of the changes we try out in the Canary Channel will never ship, and others could show up in future Windows releases when they’re ready.

The builds that will be flighted to the Canary Channel are “hot off the presses,” flighting very soon after they are built, which means very little validation and documentation will be done before they are offered to Insiders. These builds could include major issues that could result in not being able to use your PC correctly or even in some rare cases require you to reinstall Windows. We will offer limited documentation for the Canary Channel, but we will not publish a blog post for every flight – only when new features are available in a build.

Our Canary Channel won’t receive daily builds; however, we may ramp up releasing builds more frequently in the future.

The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
