No, I'm not asking anyone for their key.

I have the Half-Life CD and at one time had it running on my old PC. I
now have a new PC and want to install but have lost the jewel case with
the key.

Is there a way to recover the CD key from the old machine, either from
the registry or a hidden file? I've tried searching the registry for
valve, half-life, and sierra and have found several entries, but none of
them looks like the CD key.

If there's no way to recover the key from an old install, what's the
cheapest way to get a key? Has anyone ever gotten a replacement key from
Sierra, and if so, what's involved?

Barring help from Sierra, or just assuming it's too complicated (send in
my original CD, wait ten weeks, etc), which of the many Half-Life
versions on the market should I get if all I want is a valid on-line
key? I see the following on Amazon and am unsure if any come with keys
for net play.

- half-life: game of the year edition
- half-life 2
- half-life: counter-strike
- half-life: blue shift
- gunman chronincles
- half-life: adrenaline pack
