Microsoft Product Activation (MPA)
———————————————–
Microsoft Product Activation (MPA) is an anti-piracy technology that is designed to help verify that the product is valid. MPA is an umbrella term for technology such as Windows Product Activation (WPA) in Microsoft Windows and Office Activation Wizard (OAW) in Microsoft Office.

MPA is designed to stop a form of piracy that is known as casual copying. Casual copying is the sharing of a single license for a product across multiple, unlicensed installations.
For example, a customer purchases a copy of Windows and installs it on a computer. Then, this customer loans the media to a neighbor, who installs it on a different computer. The second installation is not legitimate and MPA is designed to prevent that unlicensed use.

How Does MPA Work:
MPA is easy to complete. For many users, it is only required one time for the life of the product. Some users may have to reactivate their product if they upgrade a significant number of components in their computer. For licensing issues, see the product’s EULA for more information.

How do I find the key for Microsoft Word? I’m reaching my 25 use limit and I’m really confused. It came preinstalled on my laptop, and I can’t find it anywhere.
