User can now “de-authorize” a PC if they would like to un-install the game from it. This is a system that is very similar to iTunes which allows for de-authorizations of computers they no longer want to use.
For example, let’s say a gamer has installed FIFA 09 on his/her home PC and work PC, using two out of five authorizations available. Then let’s say he/she decides to buy a new PC for home, and would like to install FIFA 09 on the new PC and no longer needs to play the game on the old one.
Now, With Patch #2, any gamer can un-install the game from his/her old PC and de-authorize that PC, so he/she is again at two out of five authorizations.
