is it not possible to disable media player in some way then?
basically, i don't want one of my machines to be able to run a number of the included windows programs, especially media player; outlook express; messenger.
i've disabled messenger but is there no way of doing similar to the other products which are so likely to be attacked?

any other thoughts about stopping teenagers who don't give a damn about trojans; pop-ups; auto-dialers; slow running; etc from using my main machine would be appreciated.

p.s.
the reason he wants to use mine and not his own, is that he's now got so many of the above problems (even with an a-v and anti-trojan running) that his machine is virtually unusable. however, he still refuses to follow any of my advice and i'm sick of continually formatting and reloading everything for him.
