OEM serves and showcases that the purchased software is an original valid copy of it and is generally a key which is the product number of the copy. Microsoft issues the OEM key with their operating systems serving as the product key which is asked to be entered while performing the installation of the operating system on the desktop or laptop. The product ID is an essential part of the operating system and is registered within the system providing it a distinct identity separating it from other similar official copies.
