CD key for Halo

[escobert]

My mom somehow lost my CD key for Halo. Is there anyway to get it back through the game or anything? I want to install it on my new computer but can't with out the key. Anyone know?

Do you play online?

[escobert]

Yeah.

[escobert]

Well?

Ask whoever made the game, I'm sure they'd be happy if you provided proof of purchase :p

[escobert]

WEll besides having the game I have no proof of purchase.

I'd try searching the registry ( starting with HKCU/Software/ and HKLM/Software/ ) and check files in the installation folder - I wouldn't know the precise location or method of storing it without the game myself though.
