While you can find a product key here or there, the problem is that many of them are corporate keys designated for a particular location and/or company and not usable for you system. Yes, they will sometimes work for a while ....until MS turns them off, but it is not legal or ethical to do so unless you are at the place where they are legal and/or work for that company.

The best and only solution is to purchase the key from Microsoft or from a Microsoft Distributor. According to the BSA (Business Software Alliance), ninety percent of the software sold on-line (you know the place, I'll only mention that it starts with an "e" and has four letters) is illegal in one way or the other.

Now here's your dilemma: if you "cheat" and find a key (no questions asked, right?) and use the key, you are a liar. Because when you install the OS you agree to abide by the terms of the license (or it won't install) and you have no intention of doing so (or you wouldn't be using suspect software). And you are a thief (because you know you didn't pay for the license key properly). I don't know about you, but I don't like to think of myself as a liar and a thief. So your dilemma is that you can reduce your belief in yourself and get cheap software or you can stand tall with integrity and feel good about yourself and pay for your own software. Please be selfish and buy your software from legitimate sources. :>)
