Uninstallation
When uninstalling is the process of removing software (programs) of computer systems . This not only removes files, but also resets entries in system configuration files (e.g. Windows registry ) if necessary .
Because of the increasing complexity of operating systems and their interfaces ( APIs ), deleting the program files without further changes is not only counterproductive, but also endangers the stability of a system. The quality of software is evident today not only in its productive or creative use, but also in its ability to be integrated with other software. Therefore, the provider should provide at least a manual, or better yet, an uninstall program that enables the software to be removed from the system without leaving dangerous gaps or even destabilizing the system.
More difficult this process since the intensive sharing of application libraries - even from different manufacturers - an intelligent handling of file associations and program libraries (Engl. Libraries ) requires. Occasionally, mutual dependencies lead to situations in which an uninstallation can no longer be carried out economically. In larger system environments in particular, the effort involved in deinstalling individual programs is therefore often greater and more error-prone than the installation . Many uninstaller programs attempt to circumvent the problem by asking the user if he or she might want to delete shared files that are no longer needed.
