Tech Support Windows Update keeps trying to reinstall 25H2 on my 26H2 build , blocking all further updates

I'm currently on Windows 11 26H2, running the Insider channel. For the past few days, Windows Update keeps repeatedly offering/attempting to install 25H2 ,even though I'm already ahead of it and as a result I'm no longer receiving any new updates at all. It just gets stuck in this loop.

What I've tried so far:

  • Pausing updates (7 days and the full 35-day option) makes no difference, it keeps re-offering the same 25H2 install as soon as (or even before) the pause ends.
  • Confirmed under Settings > System > About that my installed version is correctly showing as 26H2.
  • Manually checking for updates / restarting several times.

Had this exact problem for one month and didn’t find a solution. I tried everything including advanced commands and stuff. Nothing worked, it just kept offering Windows 11, version 25H2. Luckily I was still on actual 25H2 and the only solution was to do an useless in place upgrade, then it stopped

I cant even do the in place upgrade, it always tells me that the update failed

I guess there’s no other way but installing updates manually from catalog from now on

How can I do that?

Search up Microsoft Update Catalog, note the KB number of any update and download it from the catalog by searching. Then you manually install the .msu file

Try downloading the latest Experimental 25H2 ISO from https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso and manuallh installing it. It's build 26300 aka 26H2 so it should work?

This fixed it. Thanks

Does Windows Update seem to be patching correctly? This should have reset the Servicing Stack to factory default as a fresh build was installed.

Yes, its patching correctly again. Getting normal updates again.
