I am working on a friends WIN8.1 system with IE11. I want to remove the Yahoo toolbar. When I go to View > Tool Bars, and try to un-check the Yahoo toolbar I get "This action is restricted. For more information, please contact your system administrator." I've tried several suggestion on the web, but no go. There is no Yahoo toolbar in the Programs list. Using the 'X' to the left of the toolbar and selecting "Disable Yahoo Toolbar Permanently" gives me the same error.
How do I do this?
