Reminds me of how we had Windows 98 computers at school which required an administrator password to access the internet, else the system was limited to a few applications. We managed by opening a text editor or Word or whatever, file -> open, right-click a file, Explore which gave you access to the file system. Typing in an URL in the address bar changed windows explorer to internet explorer (a feature which MS later had to pay a fine and a browser selection window for), and huzzah, internets!
