Back when my high school switched from Win 98 to one of the NTs, and Ctrl-Alt-Del started being used to log in, I thought about making an application that looked like the login UI itself, as if someone else had pressed Ctrl-Alt-Del but then got distracted before actually logging in. But I didn't have the skills to do it.
The best I got was finding out how to launch cmd.exe on NT, when the system had been locked down to disallow right clicks on the desktop, no desktop icons, and only approved programs in the start menu. I think it involved navigating the help system to a certain page that had a link to Explorer. Then I explored the network until I found an unused share somewhere, where I put gcc and started teaching myself C.
The command prompt also let me use the "net send" command to send messages to other computers, which was fun.
