Here is another option:
http://www.sasg.com/mwb/faq.html#A05- Is it possible to uninstall MagicWB?
Yes. When you think you can stand the old and dull Commodore look on your workbench you can just uninstall MagicWB by re-installing the Commodore system disks. This will not delete any personal settings, it will just replace your icons and default system files. Additionally you should delete the file 'MagicWB' in your 'ENVARC:' directory and remove the 'MagicWB-Demon' line from your startup-sequence and user-startup. This is it.
Keep in mind je should probably backup your startup-sequence and/or user-startup.
