Internet Explorer 7.0 will roll out this week. It’s supposed to pop up a screen asking if you want to install it, but to be safe, disable Automatic Updates (Start/Control Panel/Automatic Updates) and wait a few weeks.
That way, tens of millions will do the final beta-testing for you. If/when it looks like there’s no monster bugs lurking, then you can install it – and disable all your IE6 add-ins before doing so (Tools/Manage Add-Ons.)
FireFox is still smarter, more intuitive and more secure. However IE 7 does have nice features.
