As sean and warpmedia mentioned, you can pretty much forget windows security
if the person can boot the box. EFS, or better yet real strong encryption,
can hinder data theft, but if you need more security look into encrypting
the entire volume upon which windows resides.
I've done a bit of research into the solutions available for these tasks,
and the best you can do is (or was about a year ago) either SafeBoot or
DriveCrypt. Google should turn up plenty on either.
If your environment requires 100% security, then you probably need to build
a concrete box, put the machine in there, cut all the cables, mortar the box
shut, and weld a steel jacket around it. (This approach will also secure you
against casual/opportunity theft.)
