IE 7 Plays Havoc With Windows XP Repair

Once you have installed Microsoft Internet Explorer 7, you must take special precautions before you do a Windows XP repair installation. If you don't, you will break Internet Explorer. (Probably because the repair installation will write a whole bunch of older IE 6 DLL files.) Microsoft says you must uninstall IE 7 before doing the repair installation -- assuming your computer is functioning well enough for that. After the repair, you can reinstall IE 7.
