Can I find serial numbers for PC games?

Most PC games are installed using a digital distribution platform such as Steam or Origin. It is possible to recover the serial number for a game installed using one of those platforms.

To find the serial number for a game installed using Steam, click on the game in your games library and click the CD-Key link in the game's information page. This will bring up a window that shows the serial number for the game itself, as well as details of any expansion packs or downloadable content that you own. Games installed via Origin have the serial key linked to the Origin account automatically.
