...maybe put the unnecessary profiles in another folder, and can profiles be deleted or renamed?
In WinXP, I've made an 'unused profiles' folder in the <C:\WINDOWS\system32\spool> directory. That seems to keep them out of trouble, but still available. You can simply delete them, if you like, but who knows when you might need one? I haven't tried renaming in place. Using left-click>uninstall profile
seems to either do nothing or generate an error.
To reinstall a profile you've moved, left click>Install Profile
. That sends a copy to <C:\WINDOWS\system32\spool\drivers\color>, while leaving the original in place.
Color-think has what looks like a versatile and useful 'profile manager' included in their product, but it's not freeware.
