Insider KB5065426 Windows 11 Insider Release Preview build 26200.6584 (25H2) - Sep. 9


UPDATE 9/12:


 Microsoft Support:

Hello Windows Insiders!

Today, we are making this year’s annual feature update Windows 11, version 25H2 (Build 26200.5074) available in the Release Preview Channel for customers to preview ahead of general availability later this calendar year.

Windows 11, version 25H2 will be delivered as an enablement package (eKB). This means that Windows 11, version 24H2 and version 25H2 use a shared servicing branch. It also means that they also share the same new features and enhancements delivered through our continuous innovation efforts. Windows 11, version 25H2 also includes some feature removals such as PowerShell 2.0 and Windows Management Instrumentation command-line (WMIC). And for our commercial customers, Windows 11, version 25H2 includes the ability for IT admins to remove select pre-installed Microsoft Store apps via Group Policy/MDM CSP on Enterprise/EDU devices. For more details on Windows 11, version 25H2, see this blog post.

Windows 11, version 25H2 shown as available as an optional update highlighted in a red box.

Windows Insiders in the Release Preview Channel can install Windows 11, version 25H2 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 25H2 if you want. Once you update your PC to Windows 11, version 25H2, 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.

Commercial* customers enrolled in the Windows Insider Program for Business can begin validating Windows 11, version 25H2 on PCs in their organizations. For these customers, the Windows 11, version 25H2 is available through Windows Update for Business (WUfB) and Windows Server Update Service (WSUS). Azure Marketplace will be available later today. 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 will be available for download for Windows 11, version 25H2 via the Windows Insider ISO download page next week. [UPDATE 9/10] The ISOs for Windows 11, version 25H2 are now available for download.

Thanks,
Windows Insider Program Team

*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.

Weird, this one below shows 4 IDs. 😂

That new admin security feature in defender is pretty neat VIVETOOL /ENABLE /ID:45172197,51406324,46471475,56508991

2 more than the ones you showed 45172197 and 51406324

Edit:
Your 2 IDs seem to work with Build 26200.6713.
But they don't enable the new UAC that asks for the authentication with the PIN.
Seems like it only enables the feature partially. 😂🤷‍♂️
The CFR keys package enables also the new UAC.
So, there must be some other IDs for that new UAC format that asks for authentication.

Administrator protection is actually running, so you can temporarily ignore the "This change requires you to restart your device." message.

I know, but it is a bug that should be fixed. And the message should pop up also when changing to off.

This bug also exists in previous OS builds.

Do you know the CFR key equivalent to the vivetool id:48433719, MS is forcing it off like in the image default and cannot be changed with vivetool.
But I'm sure it can be forced on with a CFR key.

48433719 (Vivetool ID) = 1853569164 (CFR Registry Key)

I tried the key, and it does not enable 48433719. Must be some other one.
If I enable the whole package, I see 48433719 enabled with priority 14.

Probably needs some corequisite or perhaps it is not the correct key.

48433719 is 1853569164 CFR. You can enable it yourself using Vivetool.

No, it does not allow to be enabled, it keeps showing disable in the image default.
If I enable the whole package, I see 48433719 enabled with priority 14.

Yes, perhaps they Enable state option is blocked in priority 0?

It requires another CFR Key to unlock and activate this function. The required keys are included in my registry, it just takes a long time to figure out which key it is. But it's not worth my time to find it, because the required keys may change as OS Builds change.

Too complicated, when it is enabled with the whole CFR pack, I cannot even disable it. 😂
