How do I remove Internet Explorer 7 from a windows vista system? -

I want to use IE6 for a certain website that is not that compatible with IE7, but I first have to disable IE7. On the add/remove list IE7 isn t listed as an option, so how do I get rid of it so I can use IE6

IE6 is not supported on Vista. You cannot remove IE7 from Vista.

What website is not compatible with IE7. Vista comes with it and IE6 is not Vista compatible. IE7 or try using Mozilla Firefox instead I use both and Mozilla seems to be the choice its smoother with less faults .Thanks
