hi,
when use use the winsxs (install.wim) component the maxium is removed. removing more will break the installation. there was some years ago a discussion here in the forum before the feature was implemented and a lot of tests were done
EDIT: i cant find the original thread, but there is a newer one (for win10 at least)
