HALO 2 PRODUCT ID AND LIVE ACTIVATION INFORMATION GUIDE FOR WINDOWS XP

================================================== ====================
INSTRUCTIONS ON HOW TO ACTIVATE THE PRODUCT KEY FOR HALO 2 ON WINDOWS XP
NOTICE: YOU MUST HAVE A LEGIT COPY OF HALO 2. PRODUCT ID KEY REQUIRED. HALO 2 MUST BE INSTALLED. NO DOWNLOADS ARE REQUIRED. CRACKS, PATCHES, OR ANY OTHER STUFF WILL MOST LIKELY NOT WORK. THIS WILL ACTIVATE YOUR PRODUCT ID KEY, ALLOWING YOU TO USE LIVE. HOWEVER, IT MAY BE CRASHY. HALO 2 PC WAS DESIGNED FOR VISTA, NOT XP, SO IT MAY NOT WORK FOR YOU, BUT IT MAY WORK FOR SOME. PLAYING HALO 2 ON XP MAY BE FINE ON SINGLE PLAYER, BUT IT MAY NOT BE FOR MULTIPLAYER. THERE COULD BE A WAY TO MAKE IT WORK FINE, SUCH AS SETTING HALO 2 AS HIGH PRIORITY OR FREEING UP RAM, OR A FIX THAT COULD MAKE IT LESS CRASHY AND LAGGY.

The product ID location is located in the registry, just like HALO. Go to the Start Menu > Run > regedit.
It should be located in My Computer/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Microsoft Games/Halo 2/1.0
If not, find your HALO 2 registry location or create it.
Right click and create a new PID string value in the 1.0 folder, if it doesn't work try creating the PID string values in other HALO 2 folders. In the Name column it should say PID, and the Data column should have the Product ID key.
After that, you've registered the Product ID Key. To check if it worked, start up Halo 2, go to Settings, and then About. It should have your Product ID there. (I jumped with joy when I saw it) :]
Start up HALO 2 and register for LIVE, it might take you to a broken link but go back in-game and try again/see. If you need to register or log in your LIVE account using a seperate internet browser see FAQ.
Then you should have LIVE and the Product Key activated.
