Definition - What does Crapware mean?
Techopedia explains Crapware
Cleaning up crapware involves uninstalling programs and removing any "scraps" off of the computer drive. Programs like CCleaner and PC Decrapifier can help. Challenges in erasing crapware involve potential problems with a registry, and completely untangling elements of these useless software programs from whatever else is on a PC drive. Some tech companies have tried to offer crapware removal services for a fee, but these have generally been unpopular.
