login network help

can anyone help me, win xp pro, i ran winboost top
disable access to features and did this as an
adminisatrator. Now when i log in as a guest it keeps
asking me for the office installation when logging in.
Office was installed from my main pc and i cannot get
access to the network when logged in as a guest. when i
log in as administrator i am not asked to update
(optimize) office, but as administrator i can see the
network.
