I don't think any kiosk-type applications really use iexplore -k. Instead they use their own native wrapper for Internet explorer (or maybe even another browser), which can veto certain operations so that they can't just visit a web site which links to file://c:/

In some cases this could be as simple as a .hta

In any case, with .hta or with internet explorer, it's generally difficult to prevent the user quitting with alt-f4 (unless you don't have ALT or f4 on the keyboard (which is the case on some kiosks))
