You can make the version even smaller, but who needs it like that, cut to the very tomatoes, version. Have you tried to work on such a version, no, but I tried. This is a version in which half of the functionality does not work stably. As for me, it’s nothing good – just pampering.
I did not downgrade "install.wim". I downgraded the update "Windows11.0-KB5055627-x64.msu" "install.wim" is about 3.7gb.
