Then maybe you're not in the state where it's already downloading the patch or waiting for you to reboot so it will apply it.
If the GPO didn't work (did you reboot after?), then maybe the registry hack will do. (Posted by Rodrigo Quieroz on the first page)
My upgrade is scheduled for the 28 Jan (delayed by me), yes I rebooted more than once in the last weeks. What do you think?
Moreover this is in the register, looks like the settings should be ok according to Rodrigo ... for the little I can understand
Yes, that registry entry looks correct to me.
As does the C:\Windows\SoftwareDistribution\Download - directory from your earlier post.
And you say you have rebooted while in this state?
Then - according to my mental model of how this works - Windows update should at most try to update to Windows 10 - 21H2.
But according to you, it wants to update to Windows 11, correct?
Have you checked what version of Windows you're running now? (Easiest to check with winver)
If you're already on 21H2 and it still wants to update, I must admit I'm stumped.
Hmmm... Maybe... You also mention you have paused updates for now? Maybe this 'freezes' the state of Windows Update and it will display that it will upgrade to Windows 11, even if it actually will not?
Reaching for straws here, I know.
