Microangelo Librarian (part of the sharware Microangelo icon-editing suite [sic]) allows you to extract as well as REPLACE icons embedded in .DLL, .EXE, etc. files without corrupting the rest of the file.

My version of Microangelo Librarian is only allowing me to edit the explorer icons in Emplode, not its toolbar buttons. I may have an older version of it. Does your version allow you to edit the toolbar buttons?
