Insider KB5040543 Windows 11 Insider Dev build 26120.1330 (24H2) - July 26

UPDATE 8/05:



Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26120.1330 (KB5040543) to the Dev Channel.

REMINDER: Windows Insiders in the Dev Channel will now receive updates based on Windows 11, version 24H2 via an enablement package (Build 26120.xxxx). For Insiders in the Dev Channel who want to be the first to get features gradually rolled out to you, you can turn ON the toggle (shown in the image below) to get the latest updates as they are available via Settings > Windows Update. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your device over time once they are ready.



Turn on the toggle to get the latest updates as they are available to get new features rolled out to you.

Going forward, we will document changes in Dev Channel builds in two buckets: new features, improvements, and fixes that are being gradually rolled out for Insiders who have turned on the toggle to get the latest updates as they are available and then new features, improvements, and fixes available to everyone in the Dev Channel.

Fixes for everyone in the Dev Channel​

[Settings]​

• Fixed an issue where the Windows Update page in Settings was not displaying correctly for Insiders using certain languages (no text showed). If you are impacted by this on Build 26120.1252, updating to this flight should still happen on its own, however you may need to wait a little bit.

Known issues​

[General]​

• [IMPORTANT] Windows Insiders joining the Dev Channel on PCs running Windows 11, version 24H2 Build 26100.xxxx will see “(repair version)” noted next to the latest Dev Channel build from Windows Update. This is nothing to worry about as all it means is that an in-place upgrade will happen to update your PC to the latest build in the Dev Channel.
• [NEW] The BitLocker Recovery screen issue documented here may also impact Windows Insiders in the Dev Channel.
• Adding additional languages or optional features may fail with error 0x800f081f.

[Windows Sandbox]​

• Windows Sandbox will fail to launch with error 0x80370106.

[Task Manager]​

• Navigating between different pages in Task Manager may crash Task Manager.
• [NEW] 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.

[Input]​

• [NEW] We’re working on the fix for an issue causing text suggestions for the hardware keyboard to not work properly (selecting one unexpectedly concatenates).

Reminders for Windows Insiders in the Dev Channel​

• Updates released to the Dev Channel are based off Windows 11, version 24H2.
• 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 Dev 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.
• Windows Insiders in the Dev Channel who want to be the first to get features gradually rolled out to you*, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your device over time once they are ready.
• 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.
• 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.
