ATI's Catalyst(TM) Control Center drivers come with an annoying little menu item that hooks itself into your desktop context menu.
To get rid of that shit, open up the Command Prompt as Administrator then paste in the following command:
reg DELETE HKCR\Directory\Background\shellex\ContextMenuHandlers\ACE /f
Voila! It'll work straight away with no need for rebooting.
Victory never tasted so good.
