Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26257 to the Canary Channel.

Developers, please note that for a short period of time, we will not be releasing an SDK for builds we flight to the Canary Channel.

Changes and Improvements

[ADDED 7/29] The setting to show seconds in the system tray clock has moved to Settings > Time & language > Time & date under “Show time and date in the system tray”.

We’re rolling out the ability to duplicate a tab by right-clicking on a tab in File Explorer.

[ADDED] We have updated Settings > Bluetooth & Device > Mouse to now include the option to turn off enhanced mouse pointer precision for those that would prefer to not use it and have added a new option for changing mouse scrolling direction.

If you use the netsh wlan show networks command, you should be able to read SSIDs that are UTF-8 encoded. This means that Wi-Fi SSIDs with Unicode characters (like emojis) should be properly displayed in netsh output. This change is beginning to roll out so not all Insiders in the Canary Channel will see it right away.

Updated the logic for the “End Task” option in the taskbar so that it no longer shows a Not Responding dialog to give confirmation before ending the task.

Updated System Info (msinfo32) to now follow your text size preference under Settings > Accessibility > Text Size.

Fixed an underlying issue causing some Insiders to see bugchecks in recent builds citing KERNEL_SECURITY_CHECK_FAILURE.

Did some work to help address an issue where the address bar dropdown might appear unexpectedly while you were using File Explorer.

Fixed an underlying issue leading to some of the pop-up windows in Settings unexpectedly appearing left aligned, for example, the window for selecting a custom color for Dynamic Lighting.

[IMPORTANT NOTE] We are investigating reports that some Windows Insiders in the Canary and Dev Channels are stuck on Build 26040 or Build 23620. The investigation is ongoing, however if you are impacted by this and really want to get onto the latest build in the Canary or Dev Channel today – you can download the latest ISO here and do a clean install and opt your device back into flighting in the Canary or Dev Channels.

[NEW] We are working on the fix for an issue causing the emoji panel to close when trying to switch to the kaomoji and symbols sections, or after selecting an emoji.
[ADDED 7/25] We’re working on the fix for an issue causing text suggestions for the hardware keyboard to not work properly (selecting one unexpectedly concatenates).

[ADDED] We’re investigating an issue causing graphs on the Performance page in Task Manager to not show the correct colors when using dark mode again.

The builds we release to the Canary Channel should not be seen as matched to any specific release of Windows and features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
Many features in the Canary Channel are rolled out using Control Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
To get off the Canary Channel, a clean install of Windows 11 will be required. As a reminder – Insiders can’t switch to a channel that is receiving builds with lower build numbers without doing a clean installation of Windows 11 due to technical setup requirements.

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

Check out Flight Hub for a complete look at what build is in which Insider channel.

Copilot in Windows* is being rolled out gradually to Windows Insiders across our global markets. Customers in the European Economic Area will be able to download the Copilot in Windows experience as an app from the Microsoft Store.

Thanks,
Amanda & Brandon
