Change your Half-Life and Counter-Strike cd-key easily. HL key changer is a small program which allows you to easily manage multiple Half-Life cdkeys without having to access the system registry. This is convenient when you have been banned from a certain server or want your statistics under a different player name. Now supports counter-strike retail!

Editors Note: This is NOT a key generator, but simply a way to change your product key. It is useful, for example, for someone who owns multiple copies of the game.
