NFS Undercover Deactivation
It is known that Need for Speed Undercover includes an anti-piracy protection system — SecuROM, which requires online activation of the game. Even when changing the computer's «hardware», the game had to be reactivated, and this could be done no more than 5 times, after which you had to contact EA to clear activation slots.
But recently EA launched an online service for automatic deactivation of the game, which significantly made life easier for «honest» users.
