IE is part of windows. Proof? Open windows explorer(not IE), In the Address at the top, type in Http://www.google.com hit enter. Look at that, IE is now in explorer. The core files that run windows are the EXACT same files that make up IE. They are inseperable.
Wrong. IE is used to view files but IE is not the same thing as Windows. There is more to an operating system than viewing files. At one time Windows did not use IE to view files so clearly Explorer and Windows are very much separable. MS chose to use the same tool to browse the Internet as is used to browse files but that sure as heck does not make IE synonymous with an operating system
