Use Public Access Desktop to make a foolproof workstation easily and safely used in any public place, where people have free access to it, but nobody of them can configure the system or clutter the hard disk with garbage (whether accidentally or intentionally). You can create an Internet Kiosk for cybercafe, library information terminal, in-store terminal or other public access PC. Another side it is good for limiting activities of your children on your home PC so they could have full access to the programs you specify but have no access to the workstation itself. In common case it can be set up to completely disable access to the files installed on your PC and prevent users from changing PC settings while allowing full access to all necessary applications you specify. You can selectively enable to launch any program installed on your PC, not only the web browser, mail client and office applications but also any other software you specify, can be executed and used. Public Access Desktop is a complete solution and supports multiple security modes providing you with an ability to specify the most acceptable type of access to a locked desktop such as user-name and password authentication, time-locked code (that allows users to access PC for a given period only) or a combination of both.
