uninstall

Uninstall is the process of removing a software application or component from a computing device. The goal is to remove the program's files, components, and integration with the operating system in a way that leaves the system in a usable state. Uninstalling may also remove or preserve user data according to user choice or policy.

Software installations can place files in many locations and create registry entries, services, or startup items. A proper uninstall typically invokes an uninstaller supplied by the vendor or the operating system, which performs cleanup and updates system records so the program is no longer listed as installed.

Common methods include using a built-in uninstaller provided by the software, the operating system’s package manager, or manual deletion of files. In Windows, uninstallers are accessed through Settings or Control Panel; on macOS, applications may be removed by moving them to the trash; on Linux, package managers such as apt, yum, or pacman are used.

Users should consider remnants such as configuration files, user data, licensed components, or shared libraries, which may be left behind after an uninstall. Some uninstalls offer options to retain or remove user data. In some environments, incomplete uninstall can affect updates or dependencies and may require cleanup with dedicated tools.

Uninstall procedures vary by software and platform. When possible, backing up important data before removing software is advised, and administrators should verify that no other programs rely on shared components before completing the process.
