@Proton2: If you buy a PC with Windows 7 today, not if you've already purchased. In the past I thought it used to be free. Am I wrong?

Yes, it used to be free, but I think it's always been when you purchase a computer within some timeframe prior to release. It might also have applied to purchases of a retail box of Windows, but that doesn't sound likely, if you think about it.
