Some of these keys can not be disabled easily even with C++ programs. The Ctrl+Alt+Del keystroke combination is designed not to be disabled or circumvented, for instance.
If you are using Windows NT you could try setting a system policy (and if using Windows 2000/XP, a group policy) to avoid such problems for certain classes of users (like the exam-taker one).
So you could control the environment to be very strict.
If you are setting system policies, call poledit.exe and check the "Local User Properties". There are several options, please check the Windows NT Resource Kit to learn about them. (Don't forget to have an Administrator account available if you make some mistake)
Please check the Windows 2000 Resource Kit to learn about group policies.
