[Definition] Noun: A software package that replaces a particular version of a product with a newer version of the same product. Verb: To update existing program files, folders, and registry entries to a more recent version by using Setup.exe from the installation media. Upgrading leaves existing files and settings intact, in contrast to when you perform a new installation in which all files are deleted and then reinstalled. [Term]
