Insider KB5077221 Windows 11 Insider Canary build 28020.1611 (26H1) - Feb. 12


UPDATE 2/20:

UPDATE 2/18:


 Windows Insider Blog:

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 28020.1611 to the Canary Channel (the desktop watermark is showing the wrong build number and will be addressed in a near term build). (KB 5077221)


What’s new in Canary Build 28020.1611

Changes and Improvements gradually being rolled out with toggle on*


[Built-in Sysmon]

Previously announced here, Windows now brings Sysmon functionality natively to Windows. Sysmon functionality allows you to capture system events that can help with threat detection, and you can use custom configuration files to filter the events you want to monitor. The captured events are written on the Windows event log, enabling them to be used with security applications and a wide range of use cases.


Built-in Sysmon is disabled by default and must be explicitly enabled.
  1. Go to Settings > System > Optional features > More Windows features > checking Sysmon or in PowerShell or command prompt:
    • Dism /Online /Enable-Feature /FeatureName:Sysmon
  2. To complete the installation, from PowerShell or command prompt run:
    • sysmon -i
Note: If you’ve already installed Sysmon from the website, it must be uninstalled before enabling the built-in Sysmon.

Documentation will be added to Windows soon. The functionality of Sysmon remains unchanged, learn more https://learn.microsoft.com/sysinternals/downloads/sysmon.

[Windows Share]

  • When you share a OneDrive cloud file by right-clicking to share on the file – new options for sharing that link through other apps will be provided under “Share using” when the “Copy link” button is clicked. This experience is rolling out to Windows Insiders signed in with their Microsoft accounts not in the EEA.


    Ability to share OneDrive cloud file links via other apps via the Windows share window.
    Ability to share OneDrive cloud file links via other apps via the Windows share window.

[General]

  • Fixed the desktop watermark to show the correct build number.

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
  • The builds we release to the Canary Channel represent the latest platform changes early in the development cycle. 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.
  • 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

Had to use Disk Cleanup again for deleting Previous installation. 🤬🤷‍♂️

Yup, and Edge!
It was a full install.
Also has a problem booting WinRE on DELL desktops.
Try Shift + Restart with this build and see what happens. 😵‍💫🤬

It didn't touch hardly any of my tweaks..., virtually no Reg tweaks..., just a couple appearance things I had to fix!

With this build 28020.1611 I get this problem if I try to use WinRE.
I tried on 2 Dell machines with the same result. (Dell XPS 8940 and Dell XPS 8930)
I did Shift + Restart and end up with this Error code 0xc0000428.
Anybody else seeing this problem with Dell PCs?

Offhand, it might be corrupted BCD info for the Recovery partition. I would try "reagentc /disable", and "/enable" to see if that errors out or not.

In theory, WinRE.wim gets patched at the same time as normal Windows so the two are in sync, in terms of boot file changes and driver support. Sometimes we've seen issues where WinRE doesn't get updated for some technical reason. I've seen this boot error a few times in 24H2/25H2 installs using the new Setup client, because it's actually in SAFE_OS (WinRE mode).

People just start over or just wait for the next build...

In my case I had the same issue on 2 machines Dell XPS 8930 and Dell XPS 8940. Both are in multiboot with other Builds. The other builds boot fine with WinRE.
I also tried a repair update in place with ISO created from UUP-dump but I ended up with the same issue.
I did not have this problem on 2 other machines. GMKtec M2 and GMKtec K3 which are mini PCs.

So, I restored a backup of Build 28020.1546 and found out that the problem was already in the previous Build too.
I don't know at this point when the problem exactly started, but it is definitely also in previous build 28020.1546 and now the same with 28020.1611. 😵‍💫🤷‍♂️

Same exact problem on Both Dell desktops. XPS 8930 and XPS 8940.
1770976710516.webp


Edit:
Definitely something wrong with the signature.
WinRE boots fine if I disable secure boot in the UEFI BIOS.

Same happens also after a clean install of 28020.1611 on the same Dell Desktops.

Note: there two different winload.efi files, one used by the normal OS boot and the other used by WinRE.
The signature issue is with the one used by WinRE.

I'm surprised that I don't see more users reporting this problem. 😵‍💫🤷‍♂️
