Please help; Uninstall IE 6.0

Please help! I have installed Service Pack 2.0 for win2k and now my IE won’t open html pages as a new window and I have to somehow fix it or uninstall IE6.0. I can neither remove IE nor re-install another copy… I went to MS tech pages and they simply state that I have to reinstall my OS! I think Bill Gates must have been tooo busy on his vacation to provide a more sensible solution thanks. Thanks!
