The new anti-piracy measures aren't aimed at single users, however. Microsoft isn't losing sleep over the people torrenting Office or pilfering a burned copy from a friend - instead, it is the counterfeiting involved. The software giant is concerned about knockoff copies in cloned packaging. As pirates get more professional, black market copies of Office look more like the real thing - preventing people from determining whether or not a piece of software is genuine.
To accomplish this, Microsoft is expanding "Office Genuine Advantage," a branch of the same anti-piracy arm that most Windows users are familiar with. Primarily, they are increasing how far OGA is available worldwide, and will pass it off as a Windows Update. While at first that may seem like a small act, it's actually a pretty large one - since counterfeiting is a worldwide issue, and Microsoft has largely focused on only certain regions of the world.
Whether or not nagging users with duped software is effective, Microsoft doesn't say. However, their anti-piracy efforts have increased exponentially with time. How much farther will Microsoft (or any software vendor, for that matter) go to prevent their code from being stolen?
