Announcing Windows 11 Insider Preview Build 26120.461 (Dev Channel)

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26120.461 (KB5037009) to the Dev Channel.

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.

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.

Changes and Improvements gradually being rolled out to the Dev Channel with toggle on*

[General]

• This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.

[Copilot in Windows**]

• Over the last few months, we’ve been trying out different experiences for Copilot in Windows (Preview) with Windows Insiders across the Canary, Dev, and Beta Channels. Some of these experiences include the ability for Copilot in Windows to act like a normal application window and the taskbar icon animating to indicate that Copilot can help when you copy text or images. We have decided to pause the rollouts of these experiences to further refine them based on user feedback. Copilot in Windows will continue to work as expected while we continue to evolve new ideas with Windows Insiders.

Fixes for everyone in the Dev Channel

[Copilot in Windows**]

• We are rolling out a fix for the issue causing Copilot to auto-launch unexpectedly for Windows Insiders in the Canary, Dev, and Beta Channels after restarting their PCs. This issue was unrelated to the auto-launching experience we tried out with Insiders in the Canary and Dev Channels in early February which we stopped rolling out in March.

Known issues

[General]

• [ADDED 5/6] We are investigating reports that some Insiders are experiencing an install error 0x8007371B trying to install Build 26120.461.

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.
• 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** in preview is being rolled out gradually to Windows Insiders in select global markets. The initial markets for the Copilot in Windows preview include North America, United Kingdom and parts of Asia and South America. It is our intention to add additional markets over time.

Thanks,
Amanda & Brandon
