Insider KB5081339 Windows 11 Insider Canary build 28020.1743 (26H1) - March 20


UPDATE 3/30:


 Windows Insider Blog:

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 28020.1743 to the Canary Channel. (KB 5081339)


What’s new in Canary Build 28020.1743

Changes and Improvements gradually being rolled out with toggle on*

[Shared audio (preview) gets more control]

  • Shared audio (preview) was first announced last fall, and allows 2 people to share audio between their two capable Bluetooth LE Audio headphones, speakers, earbuds, or hearing aids. With this update Windows now provides individual sliders for each listener which adjusts their volume without affecting the other. You can continue to adjust volume for both listeners at the same time through the main volume controls available through Quick Settings or on-device and keyboard controls.
  • You’ll also see a new taskbar indicator while you’re sharing, giving a quick reminder that audio is still being shared. Clicking the indicator is a fast path to open sharing settings to change volume or stop sharing.
  • The LE Audio accessory ecosystem also continues to grow. In addition to the accessories announced before, we’re excited to share that the Samsung Galaxy Buds 4 and Buds 4 Pro, Sony WF‑1000XM6, and Xbox Wireless Headset all have support for shared audio!

What’s new in Feedback Hub
  • Simpler feedback submission flow: Feedback is now submitted using a single unified template, with the added ability to search categories. The feedback form itself has been modernized enabling for faster iteration and future improvements.
  • Simpler navigation: My Feedback now lives directly in the navigation pane, and Community feedback (formerly All feedback) makes it easier to discover and engage with feedback from others. The Announcements page has been removed to focus more on giving and exploring feedback. You can still find announcements on the Windows Insider Blog.
  • New compliment feedback type: Call out what’s working well.
  • Private or public feedback: Choose whether your feedback is visible to the Insider community.
  • New focused feedback experience: a new smaller Feedback Hub surface, making it easier to provide quick, in-the-moment feedback. You can expand to the full Feedback Hub experience by pressing the button in the upper right corner.

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

Still no fix for this signature issue on WinRE. 🤬🤷‍♂️
The problem is caused by the Development PCA 2014 on winload.efi which cannot be verified by the Dell firmware on XPS 8940 and XPS 8930.
It needs to see a Windows Production PCA 2011 either embedded or in the Catalog to pass the verification.
Note that both machines have the latest available firmware from DELL for those 2 desktops. 😝🤬🤬

I tried to download and build 28020.1743 from uup-dump and it got stuck here at 69.0% for a very long time adding an update, before finally moving up to a higher %.
It eventually completed building the ISO, but it was quite a long process. 😝🤷‍♂️
