If you put ie7 in the search the site box at the bottom of topics there is a lot of information there about it. Hope this helps nobody seems to like it.
I did this and there was no way of uninstalling it so i did a systme restore! this basically allows you to set your pc back to a date before you changed anything. When i did it, it automatically came up with the last date and time BEFORE i had made any changes. All you really need to do is make sure you've saved everything properly that you've done after you installed IE 7.
Good Luck!
