is it possible to downgrade while keeping apps to older build by performing inplace upgrade from iso? i have insider canary build 27871 pro, i've patched and tried to upgrade from insider dev iso 26200.5670 pro (to get 25h2) but setup states "Your files, apps, and settings can't be kept because your current version of Windows might be installed on an unsupported directory or you're trying to install an older version of Windows"
