How to downgrade from Windows 11 22H2 to 21H2?

Hi,

I want to downgrade from Windows 11 22H2 to Windows 11 21H2, because of the bugs in that version!

But, before I downloaded Windows 11 22H2, I had Windows 10. Which means if I use the "GO BACK" option, it'll put me back to Windows 10, and I don't want Windows 10.

How can I do that?

thanks.

 

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.

 

KB5034441: Windows Recovery Environment update for Windows 10, version 21H2 and 22H2: January 9, 2024

Len, Thank you. You are correct. Microsoft is pushing the update based on all Windows 10 instead of Windows 10 Pro x86 and higher only. As you mentioned earlier, Microsoft is working on a solution. In the meantime, everyone with Windows 10 Home, need not to worry at all.

The update should only be applicable to the list below only.



Windows 10 Pro, version 21H2

Windows 10 Enterprise and Education, version 21H2

Windows 10 IoT Enterprise, version 21H2

Windows 10 Pro, version 22H2

Windows 10 Enterprise Multi-Session, version 22H2

Windows 10 Enterprise and Education, version 22H2
