Earlier this I had an interesting problem where Internet Explorer would not launch all the way on a friends computer. When the IE application was clicked on it would flash on the screen and then close immediately. I believe there was either some form of virus left on the computer that was closing Internet Explorer or that the upgrade I had just performed of IE6 to IE7 was causing a different issue. My initial plan was to continue upgrading Windows XP on this friends computer but I could not do this on the Windows Update site without Internet Explorer. Below is a work around if your Internet Explorer is not functioning properly and you would like to try to apply Windows patches from the Windows Update site anyway.
