Other types of shareware include demoware, crippleware, freeware, adware, and even spyware.
Nagware reminds or nags the user to register it by paying a fee.
It usually does this by popping up a message when the user starts the program or, worse, intermittently while the user is using the application.
These messages can appear as windows obscuring part of the screen or message boxes that can quickly be closed.
