(CoD:UO), released in 2004, represents a pivotal era in digital rights management (DRM). As an expansion pack for the original Call of Duty

for authentication. For retail physical copies, this key is typically found on a sticker inside the jewel case or the back of the manual. In-Game Activation

For players who have lost their physical key but still have the game installed, the key is stored locally in the Windows Registry
