Let's say a person performs a Clean Install of Windows XP Home, SP3. Its default Web browser is IE6, of course. Let's say this person upgrades IE directly to IE8, using the full IE8 installation file: IE8-WindowsXP-x86-ENU.exe . Let's say this person uses it for a while, adds some toolbars along the way and installs all the critical security updates. Let's say this person is not happy with IE8 (not because of the toolbars!) and would like to revert to IE6 (perhaps later upgrading to IE7). Other than uninstalling IE8 using Add or Remove Programs in Control Panel, are there any other things the person needs to do, especially in preparation? TIA.
