uninstaller

An uninstaller is a software tool designed to remove an installed program and its associated files and settings from a computer. Uninstallers typically remove binaries, libraries, shortcuts, and configuration data created by the program, and may also attempt to remove components such as services, start menu entries, and registry or database entries that reference the software.

Uninstallers locate the program's installation record, run the program's own uninstall routine if available, and then delete remaining artifacts. They remove files, registry entries on Windows, and configuration data on other systems. Many offer options to preserve user data, remove optional components, or perform a deeper purge of traces.

Types and scope: Built-in uninstallers provided by the operating system or software vendor; third‑party uninstall managers that extend capabilities; package managers in Linux distributions; and uninstallers for portable applications. Some uninstallers support silent or unattended modes suitable for automated deployments.

Platform specifics: In Windows, uninstall information is registered in Programs and Features and is often tied to MSI-based installers. macOS typically uses the application bundle or a vendor-provided uninstaller. Linux commonly uses package managers such as apt, rpm, or pacman to reverse-install packages, sometimes leaving configuration files behind.

Safety and limitations: Uninstallers may fail to remove all artifacts, leaving residual files, registry keys, or user data. Incomplete removals can affect disk space or future installations. Backups and, if needed, manual cleanup or dedicated cleaning tools should be considered. When possible, use the official uninstaller for the software or the operating system's package-management commands.
