Game Key Revealer

Game Key Revealer is just like its brethren, SoftKey Revealer except it's for games for the PC. With support over 500 games, this basically allows you to keep your games handy if you've installed them but had forgotten where you've placed the media itself.

With how big drives have become, this actually isn't that difficult to do. But in case you need to just dump all your serials and keys into a file, Game Key Revealer can do that. For Windows only.
