Poledit, user profiles....help

Hi,

I work at an average sized school in the UK. I am also the only technically competent member of staff (of course with a few exceptions). One of the teachers here requested that when a certain logon account logs on (username:pupil) she can addsome programs to the \start\programs. I know this should be a simple thing but i cant for the life of me do it. Secondly the headmaster wants a standard desktop background throughout the suites. I tried altering the profile of the user using poleditand entering the link to the image in the appropriate section. However as soon as the computer is restarted all the editing i did in poledit dissapears....and yes i did save it ;)

any help would be much appreciated,
joseph
