Product keys aren't unique to every Windows disc, and there's no way you could get it off the CD. Ask anyone who may have an old copy of '95, and get their key, if you really can't find your old one. You could also try calling MS tech support and asking them for a new key. Or to save yourself the trouble, you could try finding an alternate source for a key, which is perfectly fine & legal since you legally own the product and just lost the key.
