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

I compared the signature of the WinRE winlod.efi in Build Dev 26300.7760 and the WinRE winload.efi in Build Canary 28020.1611 the difference that pops up is the missing catalog signature in the Canary winload.efi. Both show the embedded signature as Microsoft Development PCA 2014.
The Catalog signature on the left shows Microsoft Windows Production CA 2011, the one on the right is just missing. 😵‍💫🤷‍♂️
The one on the left has no problems on booting WinRE the one on the right fails to verify the signature.

Would it be possible to copy the windload.efi file from the Dev installation and install it into the Canary?

No, according to Copilot, the signatures are different from one build to another. That would not work.
Microsoft needs to fix the Catalog signature that is completely missing in the WinRE winload.efi.
Most OEM firmware check the Catalog signature if they cannot validate the embedded signature.
The one missing on Canary WinRE winload.efi is causing the problem on Dell. Because the embedded one is with Microsoft Development PCA 2014.

These tests also explain why the normal system boot works on Canary without that problem.
The winload.efi for the normal OS boot has both the embedded "Microsoft Development PCA 2014" and the Catalog Signature "Microsoft Windows Production PCA 2011" which is completely missing in the Canary WinRe winload.efi. 😵‍💫🤷‍♂️
The only way to bypass the error is by disabling Secure Boot, clearly that is not a solution for the problem.
Note that this problem was already happening with previous Canary Build 28020.1546.

@garlin,

Further clarification after checking the WinRE winload.efi across different builds.
Copilot suggested the OEM firmware validation chain for the trust behavior.
It helped clearing the picture and why Canary fails the WinRE boot while it passes the normal OS boot.

• 26200.7840
• Embedded signature: Microsoft Windows Production PCA 2011
• Catalog signature: Missing
• Result: WinRE boots
• Reason: Production PCA is trusted directly by OEM firmware.

• 26300.7760
• Embedded signature: Microsoft Development PCA 2014
• Catalog signature: Present
• Result: WinRE boots
• Reason: Catalog signature provides a production‑signed trust path.

• 28020.1611 (problem build)
• Embedded signature: Microsoft Development PCA 2014
• Catalog signature: Missing
• Result: WinRE fails to boot on Dell systems

The correct trust behavior observed across builds is:
• Production PCA 2011 embedded signature → trusted directly → catalog optional
• Development PCA 2014 embedded signature → not trusted → requires catalog signature
• Dev PCA + missing catalog → Secure Boot failure (28020.1611)


Edit:
Checked also WinRE winload.efi on build 28000.1.
That was working because the embedded signature was with "Microsoft Windows Production PCA 2011", and the Catalog signature was missing.
Looks like the OEM needs a "Microsoft Windows Production PCA 2011" embedded or in the Catalog.
Otherwise, it cannot validate the signature and fails booting with Error code 0xc0000428.

A) If the embedded signature is with "Microsoft Development PCA 2014" and the Catalog signature is missing, it fails with Error code 0xc0000428.
B) If the embedded signature is with "Microsoft Development PCA 2014 and the Catalog signature is with "Microsoft Windows Production PCA 2011" then it boots fine. 😉🤷‍♂️

The only thing left from this version on a clean installation is that I can't access the insider program. There is some kind of error that resets the insider program to its initial state after restarting the computer. I will try to download the new Canary version via UUP DUMP and move to a higher development branch. :giggle:

@garlin,

Further clarification after checking the WinRE winload.efi across different builds.
Copilot suggested the OEM firmware validation chain for the trust behavior.
It helped clearing the picture and why Canary fails the WinRE boot while it passes the normal OS boot.

• 26200.7840
• Embedded signature: Microsoft Windows Production PCA 2011
• Catalog signature: Missing
• Result: WinRE boots
• Reason: Production PCA is trusted directly by OEM firmware.

• 26300.7760
• Embedded signature: Microsoft Development PCA 2014
• Catalog signature: Present
• Result: WinRE boots
• Reason: Catalog signature provides a production‑signed trust path.

• 28020.1611 (problem build)
• Embedded signature: Microsoft Development PCA 2014
• Catalog signature: Missing
• Result: WinRE fails to boot on Dell systems

The correct trust behavior observed across builds is:
• Production PCA 2011 embedded signature → trusted directly → catalog optional
• Development PCA 2014 embedded signature → not trusted → requires catalog signature
• Dev PCA + missing catalog → Secure Boot failure (28020.1611)


Edit:
Checked also WinRE winload.efi on build 28000.1.
That was working because the embedded signature was with "Microsoft Windows Production PCA 2011", and the Catalog signature was missing.
Looks like the OEM needs a "Microsoft Windows Production PCA 2011" embedded or in the Catalog.
Otherwise, it cannot validate the signature and fails booting with Error code 0xc0000428.

A) If the embedded signature is with "Microsoft Development PCA 2014" and the Catalog signature is missing, it fails with Error code 0xc0000428.
B) If the embedded signature is with "Microsoft Development PCA 2014 and the Catalog signature is with "Microsoft Windows Production PCA 2011" then it boots fine. 😉🤷‍♂️

Could it be an improper implementation from UUPDump?

Could it be that setting the following in ConvertConfig.ini solves the WinRE bug?
Code: 
LCUwinre     =1
UpdtBootFiles=1

According to the comments in convert-UUP.cmd:
Code: 
:: Change to 1 to force updating winre.wim with Cumulative Update regardless if SafeOS update detected
:: ignored and auto disabled for builds 26052 and later
set LCUwinre=0

:: Change to 1 to update ISO boot files bootmgr/memtest/efisys.bin from Cumulative Update
:: this also update new UEFI CA 2023 boot files if detected
set UpdtBootFiles=0

I am currently building a new Dev Build 26300 ISO,
with the following edits:
Code: 
ResetBase    =1
LCUwinre     =1
UpdtBootFiles=1
and will test it when I get the time.

Any ideas?

PS: What Academy Award, Nobel Prize, FIFA Award do I get for being the first to be impacted by the WinRE bug?

What is the brand and model of your computer?

The WinRE bug shows with Canary 28020.1546-1619, I don't have that problem with Dev Build 26300.7877. 🤷‍♂️

Much worse with 29531.1000, that fails also the main OS boot. 🤬🤷‍♂️

Looks like on some machines the OEM firmware for Secure Boot does not accept the Microsoft Development PCA 2014 certificate without a Microsoft Windows Production PCA 2011 in the embedded signature or the Catalog signature. 😵‍💫🤷‍♂️

When I downloaded and installed, and everything was normal, then restarted and it seemed ok until it started to open the canary partition, it showed automatic repair attempt-then said couldn’t repair and nothing more. Attempt to start again, would not open canary again, attempting automatic repair again and couldn’t repair. So, I could restore with macrium — all other partitions, dev, RP and beta updated without issues.
