So I'm determined to remove windows explorer completely for my system, partly for the novelty of doing so and partly to decrease memory consumption. I've already switched to using bbLean for a default shell, and FreeCommander as a file manager. So my question is, what other considerations should I be aware of before I completely nuke it? Will I have to muck about in the registry, are there any resource files that depend on explorer, and will not using explorer allow me to get rid of other processes or resources that will only be taking up space? Finally, will trashing explorer affect anything else about XP other than the shell and the file manager?
