Build 19042.906 and 19043.906 are available in RPC and Beta Channel

There's no secrecy, just a mismatch. Already pinged some folks to look into it. I'll also pass along the feedback on the extensions, but I wouldn't expect them to always match what the most recent is from WU.

Thanks Eddie. I wouldn't expect the ISO images to match recent WU. By displaying ext. one would spot an image upgrade at a glance. Same with downloading MCT for Release versions.

Regarding Suat's issue, I had clean installed a custom ISO of 19043.899 and that failed with Dism as well as WU. There should not be such a thing as mismatch in these cases. Different Error code:

Oh well, back to the drawing board on this vm. Have a great weekend Eddie, and a few cold ones around the fire. Cheers!

Hi Suat,

Does this look familiar:

Clean Installed 19043 in the RP vm. I removed the Enablement kb5000736 to use WU for RP. Not a chance. Putting this one back to snapshot of 19043.

@Eddie, would you explain why on Insider Download Page, 19043.867 ISO is available for RP while Beta still has older ISO of 19043.844.  More MS secrecy  ;-)

Regards,

Edit: Would MS kindly start including extension numbers for ISO downloads for Insider and MCT. We would know if image has been updated at a glance. Appreciated if someone from MS listens.

What SKU of Windows are you running? Have you made modifications to enable or disable features?

Hello Eddie.

In Spain it also cannot be installed

Best regards.

That error generally occurs when you make unsupported modifications to the system.
