HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Games\Halo
value name is PID, but this is only the product ID.
After googling a little, i did find this though:
Note: You must have Halo PC/CE already installed with a valid CD Key.

Ok so you lost your CD Key and are afraid to uninstall Halo. Just go to Start, Run, type in regedit and hit Enter.
When it opens up, go to HKEY_LOCAL_MACHINE , SOFTWARE , Microsoft , Microsoft Games , Right click Halo, and then click Export. Save it and then open it in Notepad. Copy and Paste the DigitalProductID into a new Notepad and save it. Now backspace the slashes and make it so theres 8 hex characters per line. Meaning 8 of the 2 letter/numbers or 16 total characters in all.

Now whenever you want to install Halo or Custom Edition, type in 0's for your CD key, and go to the regedit and double click the DigitalProduct ID in there. Then just manually edit the hexes to match the Notepad ones. Voila! Multiplayer works because you edited the bad Key with a valid one!

*this will only work if you already had a valid cd key, so no such luck for the scammers out there
