Internet Explorer has a search button in the tool bar that you can use to open a search window. By default this window is set up to use MSN Search. While there is a customize option to allow you to switch search engines, Microsoft appear to have neglected to add any of the other search engines into the selection list.
We can easily rectify this and replace the search engine attached to the search button with the more popular Google search by downloading this file and running it to update the appropriate registry entries.
