To uninstall Internet Explorer
If you encounter problems that you cannot resolve, it is often beneficial to
uninstall Internet Explorer and then reinstall it. This procedure replaces
files that might have been damaged.

2. Double-click the Add or Remove Programs icon.
· If you are using Windows XP, click Start, click Control Panel, and then

Explorer 6, you will go back to the version of Internet Explorer that was on
your computer before you upgraded
