1. Start the Windows Registry Editor by going to Start>Run and typing "Regedit" (without quotes).

2. In the Registry Editor, go to the following key:


HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers



3. Delete the 'ACE' entry by right-clicking on its folder and selecting Delete to remove the entire folder and its contents.



You can now check the effects of this immediately by going back to your desktop and right-clicking to check the context menu. The ATI Catalyst Control Center entry will be gone, but note that this cannot be "undone", so either backup using System Restore if you're not sure about this modification, or simply reinstall the ATI Catalysts and the entry will be recreated.
