I want to get internet explorer back on my computer and get rid of explorer 8. I am not happy with 8 as it isn't letting me get on msn games. The games keep on failing to load since I got on explorer 8

Go to your START/Control Panel/Add or Remove Programs

Wait till the list uploads then look for Internet Explorer 8
Right across from it you will see - Remove - Just click on that and your problems SHOULD be over

As mentioned above, just uninstalling through usual means will uninstall 8 and bring back your previous version of IE you were using
