cripple ware
Crippleware is free software, a shareware or demoware, but its functionality is severely limited compared to the full version. Hence the name crippled.
The advantage of crippleware is that although the user can test out many functions, he lacks certain functions for daily work and is therefore forced to register if he wants to use the full version. Crippleware often lacks functions for saving or printing, which means that the programs cannot really be used.
