To remove software or an application from a computer system. The reverse process of installation.
From un- prefix (reversal) + install. 'Install' comes from medieval Latin installare 'to place in a seat', from in- + stallum 'seat, place'. The computing sense emerged in the 1960s.
The concept of 'installing' software borrows from the idea of installing someone in office - both involve setting up all the necessary components for proper functioning. Modern uninstallers must carefully reverse this process, tracking down scattered files and registry entries like digital archaeologists.
