Insider KB5084491 Windows 11 Insider Canary build 28020.1738 (26H1) - March 18


UPDATE 3/20:


 Windows Insider Blog:

[UPDATE 3/18/26]: We are rolling out standalone Update Build 28020.1738 (KB5084491). This update does not include anything new and is designed to test our servicing pipeline for builds in Canary Channel. A restart will be required; device build version will not change post update.

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 28020.1737 to the Canary Channel. (KB 5079452)


What’s new in Canary Build 28020.1737

Changes and Improvements gradually being rolled out with toggle on*

[Input]

  • Pen settings: we have made refinements to the Pen settings page including small changes to the options for the pen tail button. A new option, “Same as Copilot key”, enables the pen tail button to launch the same app as the Copilot key.

Feedback: Share your thoughts in Feedback Hub (WIN + F) under Devices and Drivers > Bluetooth – Keyboards, Mice, and Pens.

Reminders for Windows Insiders in the Canary Channel

  • These builds can be unstable and may be released with limited documentation. Join Windows Insider – Get early access to Windows 11 features & updates
  • 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.
  • The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
  • Some features may show up in the Dev and Beta Channels first before showing up in the Canary 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.
  • Check out Flight Hub for a complete look at what build is in which Insider channel.
Thanks,
Windows Insider Program Team

Yep. :alien:

Insiders can take an optional update under Settings > Windows Update > Advanced options > Optional updates which will move your device from the 28000 build series to a new active development 29500 build series. Please note, because of the focus on platform development for this path, you may notice a temporary loss in some features that you have today. These features will return to this new active development build.
