Many popular programs have been preapproved and are in a software center for installation without the need for tech administrator support. Think of it as a "software buffet" where you can select the specific products you would like on your district pc. Examples of such products include Google Drive (Desktop Application), Google Earth, Turning Point 5, etc. View this brief tutorial on accessing the software center.
Note: The software center is not accesible from personal devices because you have admin rights to install whatever you wish without approval.
