How to Change Microsoft Office Product Key

Have you ever entered a pirated product key into your Microsoft Office? It can sometimes disable you from receiving critical updates, and support from Microsoft. A product key is a specific software-based key for a certain program. It is used to identify that the copy of the program is original. Product keys consist of a series of numbers or letters. This sequence is typically entered by the user during the installation of computer software, and is then passed to a verification function in the program. If you wish to acquire a licensed copy of Microsoft Office, you must change its product key to a genuine one.
