UPDATE 6/15: We have resumed rollout of Windows 11, version 24H2 to the Release Preview Channel with Build 26100.863



UPDATE 6/7: We are temporarily pausing the rollout of Windows 11, version 24H2 to the Release Preview Channel. We will resume the rollout in the coming weeks.



UPDATE 5/29: We’re aware that some Windows Insiders in Release Preview are not seeing Windows 11, version 24H2 offered yet. We’ve just begun the rollout and will gradually increase the rollout over time so not everyone will see it right away. If you are not seeing it yet and want to update to Windows 11, version 24H2 right away, you can do so by using the ISO which are available for download here. The ISO is Build 26100.560 but once you update using the ISO and join Release Preview, you’ll get Build 26100.712.



Hello Windows Insiders!

Today, we are making this year’s annual feature update Windows 11, version 24H2 (Build 26100.712) available in the Release Preview Channel for customers to preview ahead of general availability later this calendar year.

Windows 11, version 24H2* includes a range of new features such as the HDR background support, energy saver, Sudo for Windows, Rust in the Windows kernel, support for Wi-Fi 7, voice clarity and more. It also includes many improvements across Windows. For example, we are introducing a scrollable view of the quick settings flyout from the taskbar, the ability to create 7-zip and TAR archives in File Explorer (in addition to ZIP), and improvements for connecting Bluetooth® Low Energy Audio devices. We will be sharing more details in the coming months on many of the new features and improvements included as part of Windows 11, version 24H2 leading up to general availability. Please note that the new AI features such as Recall announced earlier this week will not be available on your PC after installing this update today as they require a Copilot+ PC. For more information on those new AI features and Copilot+ PCs, see this blog post here.

As part of this update, we’re also evolving the Copilot** experience on Windows as an app that will be pinned to the taskbar. This enables users to get the benefits of a traditional app experience, including the ability to resize, move, and snap the window – feedback we’ve heard from users throughout the preview of Copilot in Windows. This model also allows Microsoft to more agilely develop and optimize the experience based on user feedback. This change will be making is way to Insiders in the Canary, Dev, and Beta Channels shortly.

[ADDED 5/30] As part of the Copilot experience’s evolution on Windows to become an app that is pinned to the taskbar, we are retiring the WIN + C keyboard shortcut. For new devices that ship with a Copilot key, this key will open Copilot. For existing devices without that key, using the WIN + (number position for Copilot pinned to your taskbar) is a great way to open Copilot.

Windows Insiders in the Release Preview Channel can install Windows 11, version 24H2 via our “seeker” experience in Windows Update. This means if you are an Insider currently in the Release Preview Channel on a PC that meets the Windows 11 hardware requirements, you can go to Settings and Windows Update and choose to download and install Windows 11, version 24H2 if you want. Once you update your PC to Windows 11, version 24H2, you will continue to automatically receive new servicing updates through Windows Update (the typical monthly update process). For instructions on how to join the Windows Insider Program and join your PC to the Release Preview Channel, click here.

PLEASE NOTE: Windows Insiders in the Canary and Dev Channels will not be able to switch to the Release Preview Channel as they are on builds already based on Windows 11, version 24H2 but are on higher build numbers. These Insiders don’t need to switch.

Commercial*** customers enrolled in the Windows Insider Program for Business can begin validating Windows 11, version 24H2 on PCs in their organizations. For these customers, the Windows 11, version 24H2 feature update is available through Windows Update for Business (WUfB) and Windows Server Update Service (WSUS). Azure Marketplace will be coming soon. You can learn more about deploying pre-release feature updates using these deployment methods here. Should any issues arise, IT admins in organizations deploying Release Preview updates can request Microsoft Support.

And finally – ISOs are now available for download for Windows 11, version 24H2 via the Windows Insider ISO download page.

Known issue​

[ADDED 6/3] After updating to Windows 11, version 24H2 (Build 26100.712), you may see an Pcasvc.dll error dialog pop-up with the message “Missing entry: PcaWallpaperAppDetect”. We are working on a fix, but you can follow these instructions to mitigate the issue:
  1. Type “Task Scheduler” in the search box on the taskbar to find and open Task Scheduler.
  2. On the left tree view of Task Scheduler, click on the “Task Scheduler Library” to expand the node.
  3. Keep expanding the nodes by clicking on the tree view in the following order: Microsoft -> Windows -> Application Experience.
  4. After clicking on the “Application Experience” node, find the task named “PcaWallpaperAppDetect” from the list view in the middle of Task Scheduler.
  5. Right-click on that task, click “Delete” in the pop-up menu. Then click “Yes” on the confirmation dialog box asking, “Do you want to delete this task?”.

Thanks,
Windows Insider Program Team

*Please note that Cortana, Tips, and WordPad are removed after upgrading to Windows 11, version 24H2. These apps are deprecated.

**Copilot in Windows is being rolled out gradually to Windows Insiders across our global markets. Customers in the European Economic Area will be able to download the Copilot in Windows experience as an app from the Microsoft Store (coming soon).

***We consider a device a commercial device if it is not running the Windows 11 Home edition AND is being managed by an IT administrator (whether via Microsoft Endpoint Manager or other management solution) or has a volume license key or commercial ID or is joined to a domain.

Just did a reboot and now I get the New Outlook every time I open the Mail or Calendar app. Switching the toggle loads Mail app but then New Outlook opens again next time.

For now I've uninstalled New Outlook

Thank you for this.
I recall seeing something like this on a VR forum, but the problem was that it contradicts what Microsoft originally said, which was Win 11 24H2 would no longer have WMR functionality.
It's quite misleading, because this November 2026 date actually only applies to 23H2, which is when 23H2 reaches EOL.
Regarding 24H2 here's the official link to deprecated features, I've pasted the part about WMR:

"Windows Mixed Reality is deprecated and will be removed in Windows 11, version 24H2. This deprecation includes the Mixed Reality Portal app, Windows Mixed Reality for SteamVR, and Steam VR Beta. Existing Windows Mixed Reality devices will continue to work with Steam through November 2026, if users remain on their current released version of Windows 11, version 23H2. After November 2026, Windows Mixed Reality will no longer receive security updates, nonsecurity updates, bug fixes, technical support, or online technical content updates.

This deprecation doesn't affect HoloLens. We remain committed to HoloLens and our enterprise customers."
Sadly, you are right, I have been on 24H2 for a while on Canary and I can still install the portal but the message below is displayed when launched.
Try to stay on 23H2 then.

Two PCs here running 26100.712 RP. A couple of times I've had this error after signing in
Both PCs have had the error but it doesn't seem too serious.
Both have the 'Dynamic Theme' wallpaper app installed - could be related?

Weird thing is - both PCs will go a few days with no error, then both do it on the same day/time. It's not random! If one does it then the other will

Since installing 24H2 on 05/22, I've been unable to use WireGuard 0.5.3 (the official WireGuard app). I can establish a connection, but no internet traffic passes. Everything was working flawlessly for >1 year until the minute my computer rebooted after installing 24H2. I've uninstalled 24H2 and it still won't work. Reset network connections, deleted the client from my VPN server and added again, rebooted my VPN server, updated back to 24H2. Uninstalled and reinstalled WireGuard 0.5.3. Nothing seems to fix this after it was borked with the 24H2 update.

Is anyone else having similar issues?

Some apps that worked under 23H2 no longer run under 24H2. You need to wait for them to be updated.

Borked is a good way of saying what happened to you. I like that word and it means a lot about my system too.;-)

Have you considered restoring your system with a backup image?

Is anyone else having similar issues?

I had this happen with Wifi analyzer. I uninstalled the app and reinstalled it and it worked. Maybe worth a try.

Two PCs here running 26100.712 RP. A couple of times I've had this error after signing in
Both PCs have had the error but it doesn't seem too serious.
Both have the 'Dynamic Theme' wallpaper app installed - could be related?

Weird thing is - both PCs will go a few days with no error, then both do it on the same day/time. It's not random! If one does it then the other will
Had that same error but could not isolate exactly when it happens.
In one case I was trying changing the colors for the new Copilot App, in another case when the Windows Spotlight was changing the background picture.
Another bug for MS to figure out. 🤷‍♂️

I'm getting that very same RunDLL dialog, although I have only seen it one time so far.

The new Copilot app? I uninstalled it. I never use it. I see no use for it. Guess I'm just old school and still Google everything as I did on Win 10.

Had that same error but could not isolate exactly when it happens.

Hi,

Check your Task Scheduler > Library > Microsoft > Windows > Application Experience : PcaWallPaperAppDetect : You will see when it happens in the Triggers column.

In order to avoid this error while Microsoft fix this, you can safely disable the PcaWallPaperAppDetect task.
