XCOPY deployment or xcopy installation is a software application's installation into a Microsoft Windows system simply by copying files. The name is derived from the XCOPY command line facility provided by Microsoft operating systems.
In contrast, the installation of a typical Windows application will require a significant number of additional steps before the application is ready to be used. Most of this additional work involves, directly or indirectly, adding or modifying entries in the Windows Registry. Even when an application uses ordinary files for its own data, many common facilities provided by Windows require some type of registration step before they are available to programs. Usually, one or more specialized tools (such as Windows Installer, InnoSetup, or NSIS) are used to help coordinate these relatively complex operations.
