Can I use Group Policy to deny software installation?

I have done some research and found (and implimented...thank you again,
Steven) ways to deny student users under our domain to launch certain
installed software, but is there some way (a domain-level group policy,
perhaps) that I can keep them downloading/installing certain programs in the
first place?

Also, how might this impact their ability to use key drives under Windows
2000/2K?

Thank you in advance for any insight in this matter.
