Crippleware

Shareware, or promotional software, which has been crippled, i.e. some functions, such as printing or saving files, have been disabled by the developer. Whilst logical from the developer's perspective, its popularity has fallen, as it fails to allow the user to use the system properly and hence can avert sales, rather than promote them. Far better is the technique whereby the software is fully functional for, say, 30 days, and then refuses access until a licence string is entered. Even the removal of the software and a re-install will not result in a further 30 days. Why? - because the developers are smarter than that! Upon installation, a tiny hidden file is created in a secret location. This file and its contents are read upon start up, and thus the user is forced to make a purchase decision.
