Product Key

A product key, also known as a software key or activation key, is a unique code used to activate and verify a licensed software product. When a user purchases a software product, they receive a product key that unlocks the full version of the software and enables them to use all the features. Product keys are typically used for commercial software, such as Microsoft Windows and Microsoft Office, but can also be used for other software applications. Users must enter their product key during the installation process or activate it online to confirm that they have a genuine copy of the software.
