I thought some components/software are using IE core to work? Like Yahoo! Messenger and MSN Messenger?
usually, if you uninstall IE7, it revert back to IE6, so you still have IE

in his case, I suspect he installed IE7
before he upgraded to XP SP3 which disabled uninstallation of IE7
if he install IE7
after XP SP3, he can uninstall IE7 and use IE6
