I only leave bout 6 components, Paint, Notepad, Photo Handler thingy, game explorer, BITS, Windows Updates and something else. but i do i remove WinSXS, i even mount the wim, use a duplicate file finder and remove all the duplicates in WinSXS (saves about 60MB) as well as some other stuff. and all my updates install fine. Every update that appears i integrate into my next install, but ye... the new ones still install. I've done about 2 more installs since started this topic and still install fine with Component Cache removed.
