If reset and export/imprt registry don't fix the probem, try to set default programs. In my case, I open IE>Internet Options>Programs>Set default program>Set program access and computer defaults. I selelct both IE and Outlook as default programs.

Or check thsi quoted.

Windows XP and Vista allow you to control program defaults through Control Panel. If the above methods fail, use this method to set the default browser. In Windows XP, go to Add and Remove Programs, Set Program Access and Defaults. In "Choose a default web browser", check on the "Internet Explorer" option and click the OK button. In Vista, access the Default Programs applet from the Start menu or Control panel. Click on the "Set program access and computer defaults" (last option) then expand Custom. In "Choose a default web browser", check on the "Internet Explorer" option and click the OK button.
