From the Kick 'em When They're Down dept.:
...Mitchell Baker, chair of the Mozilla Foundation, and Harvey Anderson, the foundation's general counsel, have both blogged about the proposal, with both of them stating that according to them, it's not good enough. They mostly trip over the fact that selecting another default browser in the ballot screen does not automatically remove the Internet Explorer icons from the desktop and Windows 7 taskbar

To remove these icons, you either have to delete them manually, or uninstall Internet Explorer altogether, as will be detailed how to in the ballot screen. I find this a perfectly acceptable setup, as I see no reason why installing application Abc should remove my shortcuts to application Xyz. I would find it highly inappropriate for a ballot screen to magically remove my shortcuts.
