uninstallerA {utility} program to remove another {application program} from a computer's disks. Most commonly found on {IBM PCs}, as applications tend to leave files in various places on the {hard disc}, so special software is required to tidy up after them. Ken Spreitzer claims to have written the original PC program called "UnInstaller", first licensed to {MicroHelp} and now (Feb 1998) sold by {CyberMedia}. Compare with {installer}. (1998-02-09)
