Started with IE as default. Without changing anything, IE would open in Metro mode using start menu. It would open in desktop mode when started from Desktop. Installed Chrome; set it as default. Now am unable to reset IE as default to be able to use IE on start screen in Metro mode. The box I need to uncheck in Internet Options is greyed--allowing no change even after resetting IE as default. Any thoughts? Well, other than I shouldn't have set Chrome to default.
