Insider KB5054148 Windows 11 Insider Dev build 26200.5510 (24H2) - March 24


UPDATE 3/28:


 Windows Blogs:

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26200.5510 (KB5054148) to the Dev Channel.

Starting today, the Dev Channel is jumping ahead to receive 26200 series builds. This means that the window to switch from the Dev Channel to the Beta Channel is closed and once you install Build 26200.5510. If you are in the Dev Channel today and still want to switch to the Beta Channel at the last minute, when Build 26200.5510 is offered you can pause updates in Windows Update and switch your channel to the Beta Channel and un-pause updates.

These 26200 series builds are based on Windows 11, version 24H2 and will contain many of the same features and improvements as the 26120 series builds that will continue to be released in the Beta Channel. Over time, we be making behind-the-scenes platform changes in these builds and these builds may have different known issues because of those changes than what we’re flighting to the Beta Channel.

In the case of Build 26200.5510 today – this build contains the same features and improvements as Build 26120.3576 released previously.

As always, if you experience any issues while you use your PC on these builds we release to the Dev Channel, please file feedback in Feedback Hub.

IMPORTANT NOTE for Insiders on Copilot+ PCs: Please note that when you update from Build 26120.3576 to Build 26200.5510 on your Copilot+ PC, you will see your snapshots in Recall and Recall settings get deleted and reset.

Known issues

[General]

  • After you do a PC reset under Settings > System > Recovery, your build version may incorrectly show as Build 26100 instead of Build 26200. This will not prevent you from getting future Dev Channel updates which will resolve this issue.
  • The toggle to get the latest updates as they are available via Settings > Windows Update is not rendering correctly and gets turned off by itself. This is just a visual issue and will be fixed in a future flight soon.

[Recall]

  • [REMINDER] Make sure you update Microsoft 365 apps to the latest version so you can jump back into specific documents.
The following known issues will be fixed in future updates to Windows Insiders:
  • Some people may experience Recall being no longer able to save new snapshots or modify settings. This will be fixed in a future flight.
  • Some Insiders may experience an issue where Recall is unable to automatically save snapshots, and the setting can’t be turned on in Settings. We’re working on a fix for this issue.
  • Recall can be enabled or disabled from “Turn Windows features on or off”. We are caching the Recall binaries on disk while we test add/remove. In a future update we will completely remove the binaries.

[Click to Do]

  • [REMINDER] The intelligent text actions are now locally moderated to ensure the safety of prompts and responses and has replaced the cloud endpoint. Now that these intelligent text actions are fully local, they are also available in Click to Do in Recall.
  • [REMINDER] If any of your actions on image entities are no longer appearing, please ensure you have the latest updates for the Photos and Paint app from the Microsoft Store.
The following known issues will be fixed in future updates to Windows Insiders:
  • Sometimes additional context is given when using more intelligent text actions powered by Phi Silica.

[Improved Windows Search]

  • [REMINDER] For improved Windows Search on Copilot+ PCs, it is recommended that you plug in your Copilot+ PC for the initial search indexing to get completed. You can check your search indexing status under Settings > Privacy & security > Searching Windows.

[File Explorer]

  • We’re working on the fix for an issue causing File Explorer to be very slow to close for some Insiders when closing using the X button. This may also have an impact on the other title bar buttons.
  • We’re working on the fix for an issue causing File Explorer Home to crash for some Insiders. If you launch File Explorer to a different folder (for example, using search or the Run dialog), you should be able to navigate your folders.

[Taskbar]

  • We’re working on the fix for an issue where the taskbar icons aren’t increasing in size as they should when using your PC in a tablet posture.

[Task Manager]

  • After adding the new CPU Utility column, you may notice that System Idle Process always shows as 0.
  • The CPU graphs in the Performance page are still using the old CPU utility calculations.

[Widgets]

  • The weather widget may temporarily be unavailable.

Reminders for Windows Insiders in the Dev Channel

  • Windows Insiders in the Dev Channel receive updates based on Windows 11, version 24H2 via an enablement package (Build 26200.xxxx).
  • Many features in the 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 this channel.
  • For Windows Insiders in the Dev Channel who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.
  • 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.
  • 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.
  • Please note that some accessibility features may not work with features like Recall and Click to Do while in preview with Windows Insiders.
  • Because the Dev and Beta Channels represent parallel development paths from our engineers, there may be cases where features and experiences show up in the Beta Channel first.
  • Check out Flight Hub for a complete look at what build is in which Insider channel.
Thanks,
Amanda & Brandon

Those with fond memories of the last time we got a full-build update, in October or so, might recall the need to make an ISO and upgrade that way, due to 0xc1900101. The same thing appears to be happening this time, and I think that was the only way past it. The perils of using a non-compliant PC, but at least the problem doesn't happen with CUs.

Well that was quick I am currently running a Windows To Go Insider build and previously I had no trouble upgrading using Windows Update but this time Microsoft is blocking the Installation as not compatible :(, I guess the only way to upgrade is to find another NMVE slot on the mobo or use rufus to create a new Windows To Go USB Installation of this new build.

Updated this morning. Exported the Windows Metrics registry key first as feature updates always reset these to default. All completed seemingly OK. I'm always interested in how much space these things consume. 118Gb free falling to 110Gb after update downloads. 92Gb free after update installs and back to 116Gb after a cleanup.

All good at this point. Macrium images made along the way.

Check download folder, more than 8G, so it's not Cumulative Update, it's whole new build.

Yes, it is a feature update, a new build that leaves a 'Windows Old' folder of the previous installation that can be deleted.

Unfortunately, I have not installed the update. He downloads everything, installs it and will then perform a restart to complete the update. Looks normal and successful at first. When I log in again, I see that under Updates it says "Installation error"... see screenshot.

I have already downloaded the ISO and tried to install, there is only "Cannot be installed". I'm currently on 26120.3576.

Do you have an idea?

I forgot about that on my unsupported System Two and failed on my first attempt through Windows Update. Second time round I used the registry patches from Option Three in Brink's tutorial before checking for updates and succeeded.

26200 already was (26200.5001). Is MS run out with build numbers ?

26200.5001 was the Canary build from April 19, 2024. Looks like MS chose that as the base for the Dev build going forwards. Meanwhile Canary is now on the 27000 series of builds.

There's nothing unusual in this, Insider builds start off in the most experimental channel, then when deemed stable enough a build can filter down to lower channels. Remember, 24H2 RTM 26100 started life in the Canary channel on April 3, 2024 before moving to Insider Release Preview channel on May 22, 2024 as build 26100.863.

The builds history across the Insider channels can be seen at the Insider Flight Hub.

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 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, and 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2.

I forgot about that on my unsupported System Two and failed on my first attempt through Windows Update. Second time round I used the registry patches from Option Three in Brink's tutorial before checking for updates and succeeded.

Hmmm, I knew about that, and have used it another system in another situation, but didn't think it mattered to WU. Tried it, rebooted, but it still went right back in with 0xc1900101.

I'm going to try it again though, this time with Skip_TPM_Check_on_Dynamic_Update_v13.cmd disabled. This is what I use normally to allow WU, but I know that it can sometimes get in the way, and this may be one of those times. I'll edit this post with what I found later.

If that doesn't work though, I wonder what you're doing differently? Can you think of anything? I'd love to have a trick like this up my sleave to avoid making an ISO, which takes several hours.

Not a lot different here, Skip_TPM_Check_on_Dynamic_Update_v13.cmd is my usual 'goto' as well. After forgetting to turn it on I did turn it on, but it still failed. That's when I turned it off, rebooted, and used the registry patches - and Windows Update could finally install the upgrade.

I've had no chance of installing it either. I've tried everything possible, including skipping TPM, etc., but I just can't get it to install, while my Intel computers have no problems. On this one, where it doesn't work, it's been running Windows 11 since Saturday, and so far, all the updates in the DEF have worked, except for this one... always just 0xc1900101
