Hey, How do I get Windows 11 26H1, as I've still got 25H2? Kind regards, Damo

Hi, You either wait for the next update or go to the link that David posted above and download the ISO for build 28020, after the download open the folder and run Setup from there.

This could also be part of your problem, Optional Diagnostics has to be On.

Hi, Going to ask, is your PC fully Windows 11 compatible? Run this: https://aka.ms/GetPCHealthCheckApp If it is, then at this point I would use the Media Creation Tool and do a total clean install and then rejoin Insiders. Backup important files, documents, photos, etc. first.

Hi, Glad you finally found the correct link.

Please go to this link (not the catalog)

https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso

And download this ISO:

Mount the ISO, then open the file and click Setup.

I think I'll wait, because if I go to that link and download the ISO, when I try to install it, I get this error message:

This is what my Diagnostics & Feedback screen looks like:

Everything is grayed out, and I don't understand why.

Run this: https://aka.ms/GetPCHealthCheckApp

If it is, then at this point I would use the Media

Creation Tool and do a total clean install and

then rejoin Insiders. Backup important files,

documents, photos, etc. first.

It is. But I will wait for now, as I can't back up my files at the moment. But thanks anyway.
