Just did a full reinstall on a Pentium 4 PC on a Foxconn mainboard. Standard stuff, drivers and Windows Updates, including upgrading to IE7 however, as I created a second user and went to setup her desktop, the Desktop Items tab under Display Properties only shows My Computer, My Documents and My Network Places. Internet Explorer and its tick box are nowhere to be found. Back to the original user, and things are just the same, although user 1 has IE on the desktop - obviously the option disappeared somewhere during the installation of drivers, updates etc.
I just want to clarify that this is NOT a case of restoring the IE icon to the desktop - I'm good at that, but the OPTION to place the icon on the desktop is gone!!
