 Windows Blogs:

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26100 to the Canary and Dev Channels.

The Canary and Dev Channels receiving the same builds is only temporary. During the times in which the Canary and Dev Channels are on the same builds (e.g. Build 26100), the window is open for Insiders in the Canary Channel to switch to the Dev Channel. In the near future, the Canary Channel will jump to higher build numbers and the window will be closed so make your choice on which channel to be in soon!

Change Windows Insider Program Channel in Windows 11 Tutorial

This tutorial will show you how to change your Windows Insider Program channel to the Canary Channel, Dev Channel, Beta Channel or Release Preview Channel to get Insider preview builds of Windows 11 on your PC. Flighting is the process of running Windows Insider Preview Builds on your device...
www.elevenforum.com www.elevenforum.com

NOTE: Some features may begin rolling out to the Canary Channel first before the Dev Channel even if the two channels have the same build.

What’s new in Build 26100​

Changes and Improvements​

[General]​

  • [REMINDER] The build watermark at the lower right-hand corner of the desktop is not present in this build and will return in future Insider Preview builds. This is part of our normal process preparing Windows 11, version 24H2 for releasing to customers later this year – but does not mean we’re done. Windows 11, version 24H2, will be this year’s annual feature update. As mentioned here, Windows 11 will have an annual feature update cadence that releases in the second half of the calendar year.

Fixes for known issues​

[General]​

  • Made another fix to address the issue causing shutdown and hibernate to not work in the latest builds.
  • Fixed an issue resulting in some Insiders seeing error 0x80240067 when trying to download app updates from Microsoft Store or Windows updates in Settings in the latest builds.

[Copilot in Windows*]​

[Windowing]​

  • Fixed a DWM crash impacting some Insiders in the latest flights (this could result in you seeing your screen flash black).

Known issues​

[General]​

  • [IMPORTANT NOTE] We are investigating reports that some Windows Insiders in the Canary and Dev Channels are stuck on Build 26040 or Build 23620. The investigation is ongoing, however if you are impacted by this and really want to get onto the latest build in the Canary or Dev Channel today – you can download the latest ISO here and do a clean install and opt your device back into flighting in the Canary or Dev Channels.

[Copilot in Windows*]​

  • [ADDED 4/12] We are aware of reports by Insiders in the Canary and Dev Channels that Copilot is auto-launching unexpectedly after restarting their PCs. We hope to have a fix for this issue soon and is 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.
  • Voice access does not work reliably with the updated Copilot in Windows experience that introduces the ability for Copilot to act like a normal application.
  • Using Windows Ink to write in Copilot will not work with the updated Copilot in Windows experience that introduces the ability for Copilot to act like a normal application window.
  • When Copilot in Windows is docked and resized to a large width, Copilot does not always fill the width of the panel. Resizing Copilot usually fixes this issue.

For developers​

You can download the latest Windows Insider SDK at aka.ms/windowsinsidersdk.

SDK NuGet packages are now also flighting at NuGet Gallery | WindowsSDK which include:
These NuGet packages provide more granular access to the SDK and better integration in CI/CD pipelines.

SDK flights are now published for both the Canary and Dev Channels, so be sure to choose the right version for your Insider Channel.

Remember to use adaptive code when targeting new APIs to make sure your app runs on all customer machines, particularly when building against the Dev Channel SDK. Feature detection is recommended over OS version checks, as OS version checks are unreliable and will not work as expected in all cases.

Reminders for Windows Insiders​

  • The Canary and Dev Channels receive builds with features and experiences that 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 and 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 these channels.
  • As the Canary and Dev Channels receive the same builds, some features may begin rolling out to the Canary Channel first before the Dev Channel.
  • While the Canary Channel is now on Windows 11, version 24H2, this is just temporary. At some point in the future, the Canary Channel will jump ahead to receiving new builds not matched to any specific release in a higher build series.
  • To get off the Canary or Dev 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.
  • The desktop watermark shown at the lower right corner of the desktop is normal for these pre-release builds.
  • 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

For any veterans of 0xc1900101 from past builds, any tips? Not sure why it's happening here now and not before, but I'm going to try a uupdump iso to see if that gets around it as they sometimes can.

Does anybody get this problem with MS Store updates?
With the last 3 Canary/Dev builds 26085, 26090, 26100, if I use the ISO from UUPDUMP to update the system I cannot update some of the MS Store apps after the build is updated.
I get the messages below and there is no way to update those Apps.
The problem does not happen when I update the same systems with W.U. only when I use the ISO to update or update/repair in place.
I 'm trying to prevent downloading the same build over and over for different machines, but this problem forces me to use W.U. for every machine. 😝🤬
This problem does not happen if I use the same ISO to do a clean install, it only happens after an update from a previous Canary Build or an update/repair in place of the same Build.

When I became an Insider I did it for the excitement of being one of the first to test out new features so I could help find any problems before they were released to the general public. With what is being released lately the excitment isn't there anymore. For me the excitement has turned to seeing how many tries it takes to successfully update. I know I can always drop out by doing a clean install but I'm not ready to give up yet.

It's not that bad using Windows Update, not if you allow downloads from other PCs and update more than one machine at a time. I keep Task Manager open at the Performance tab and watch the network activity, with two machines downloading the same builds in WU I have seen one send updates to the other.

When 11 was released on 5th October it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update.

Wanted to try a uupdump iso to see if gets around 0xc1900101. I was surprised to hit this right away with the mounted iso:.

While it's true, it's also true that I not only have "Skip_TPM_Check_on_Dynamic_Update.cmd" in effect but also the extensive reg file from elsewhere on this site (BypassSecureBootCheck, etc). Anyone know why?

Is that still a legacy BIOS PC?
Why is Secure Boot not available? I thought Secure Boot was available on any UEFI machine. 🤷‍♂️

Is that still a legacy BIOS PC?
Why is Secure Boot not available? I thought Secure Boot was available on any UEFI machine. 🤷‍♂️

It is Legacy. I'm baffled why the ISO method doesn't work. I even tried the appraiserres.dll swap, no-go.

Note that I never normally have to think about this, since I just use WU and Skip_TPM_Check_on_Dynamic_Update.cmd does its thing. Only went to the ISO because of the WU problem. Maybe it's the very same issue though just expressed in two different ways.

It has been a while; I think MS blocked the Legacy BIOS several Canary Builds ago.
I cannot even Boot the installation media on a Legacy BIOS machine, because MS changed the bootmgr file to post a disk error when trying to boot. I replaced the file with an older one to work around the problem, but then it fails the same way when trying to boot the installed system.
I gave up using Legacy Bios with Canary 2 or 3 months ago.

That would have made big news. You're not thinking of that POPCNT feature, right? That was one notable change a few months ago but only applied to CPUs that predated something like 2009, at least on the Intel side.

When you say that you haven't been able to use Canary builds, do you mean even on systems that had been working? Because that's all I've been dealing with. I don't have any recent experience on new installs.

Yes, a system that has been working with older Canary and Dev Builds and still works with 22631 and 22635, it does not work with any of the latest Canary or Dev 26xxx.
POPCNT is not an issue it is a pretty old instruction added 17 years ago. 😉

That's so weird. I hope you can narrow why it is, but it can't strictly relate to legacy bios in general, since I most definitely don't have UEFI. The Bios Mode according to msinfo32 is Legacy.

On today's issue here with me, uh, I have no good explanation for any of it. I failed 6 times in the first half of the day and then stopped trying things because nothing was working. Late in the day I tried the WU one more time, but since I was sure it wouldn't work I deferred rebooting until pretty late tonight. As soon as I clicked reboot, it went to a type of screen that I don't quite recall seeing before, one that went from 0% to 100% pretty quickly but notably said that it was updating.

Did MS perhaps push some kind of compatibility fix late in the day given that the lone Known Issue is related to upgrades? If they did, I guess we'll hear about it tomorrow, but I have no other explanation for what happened after the reboot: it went through the rest of setup. In other words, it worked and didn't just bounce right back into Windows as it had done the first half dozen times today. I didn't change anything, so it feels more like MS did.

And, if that don't work, MS can take this Build and stick it where the sun don't shine! There's no way in hell I'm gonna run that lame-a$$ Explorer SDK!
