Windows 10: Stuck on "undoing changes" for Windows 11 22H2 feature update

I am running Windows 11 21H2 build 22000.1817 and my Windows Update comes back with wanting to install Feature Update 22H2, and as we have a certified security compliance I soon must get it installed.Normal updates install just fine, e.g. yesterday it installed `2023-04 Cumulative Update for Windows 11 for x64-based Systems KB5025224` and then rebooted afterwards and everything worked as expected.However, every time I try to get the 22H2 feature installed the same thing happens, it installs, and then reboots.

Cannot update Windows 11 to build 22h2

Need more help than support web site offers. I would like to update a Windows Pro 21h2 to 22h2.

I've tried every suggestion at Troubleshoot problems updating Windows - Microsoft Support short of "Perfrom a clean installation of Windows 11." That list is comprehensive and includes everything I would have thought of on my own and then some. None of the troubleshooting suggestions solved the problem. The system in question is a Lenovo ThinkCentre M90n desktop running Windows 11 Pro Version 21H2.

In addition to all the steps at the above link, I've also tried installing by using Windows 11 Installation Assistant. Installation Assistant downloads and goes through the long installation process. But then very shortly after the reboot starts, it says, "Undoing changes" and boots back into the old build.

 

Win 10 vs Win 11 - Features & Changes

Thanks- presumably that's for build 21H2. Just needs to be slo-ow-ed down (a lot).

Coming- the next major changes to Win 11 as 22H2. Here are a couple of random review sites:

JW Library and Windows 11 22H2 Update and Feature update crash.

If you are having trouble opening JW Library after updating to Windows 11 22H2 and then after updating the feature pack that includes tabs in My Computer and JW Library will no longer install .jw[ub files, there is a work around.

First these are 2 separate issues.

1) Upgrade to Windows 11 22H2 and JW Library will no longer stay open.

2) Upgrade to the feature pack that includes the tab My Computer, JW Library can no longer install .jwpub files.

Both issues have different causes, I have been unable to find either. However I have posted 3 videos 1 as a work around to the 22H2 update, the other as a fix to the 22H2 update and feature update.



Currently it is the only fix.
