Lost product key for Halo

[Braxen814 0]

I just moved from Virginia to Missouri.. and I lost a few things along the way lol. But somewhere along the line I lost my product key for Halo and was wondering if there is any way to get it back with the product part number or anything like that, if someone could get me the link so I could use this to get my product key back I would be extremely grateful

If you have it installed, try Product Key Explorer.

 

.edit

Ignore that, "demo" version does not display complete keys...

 

But found this:

Retrieving your Product Key from the Registry @ Gearbox Software Forums.
