BTW: there is a Plug in for firfox tha allows you to open a link in IE.. The plugins are bloody handy..
As for win updates?.. whats the problem ..unless you are planning to remove IE completly..
MyIE2.. is good.. GAve it away after using Firefox on test for a month.. neither are perfect..

useing Firefox at home I have the very little cleanup of Crap each week on any of the machines.. especialy 15yo daughters..

Cheers
