If you have been a Windows user for years, we're sure you have used either Internet Explorer 5, Internet Explorer 6 or Internet Explorer 7, and you'll know how to do things quicker with it than with the Safari browser that is included by default on all Apple computers, thus making it a good idea to have Internet Explorer 5 handy to complete searches and browser.
