This build of windows is going to expire on 31st October. How do i fix it

I also did a post about that: https://techcommunity.microsoft.com/t5/windows-insider-program/unable-to-upgrade-to-windows-10-21h2/m-p/2877690

Since we are in Windows 11 builds numbers (even if we were in Windows 10) there is no clear upgrade paths to Windows 10 21h2.

Microsoft did an announcement regarding this with a very unclear procedure.

When i choose Release preview I get nothing.

https://blogs.windows.com/windows-insider/2021/10/19/releasing-windows-10-build-19044-1319-21h2-to-release-preview-channel/

So far my only option without losing data would be install Windows 11 on unsupported hardware unless Microsoft provide a fix.

EDIT: Thinking about that. The Microsoft procedure probably only apply to builds in the beta or release preview. Changing branch probably wont fix anything..
