Microsoft tightens Windows licensing

Microsoft has renewed the OEM license agreements for its operating system. From this point on, the license is no longer attached to the machine as a whole, but to the motherboard, which is considered the heart of a computer.
So, customers will have to acquire a new license if they change this component.
It should be noted that, contrary to Mac OS X which updates approximately every year, Windows, and in particular XP, is in production for a very long time, much longer than the a computer's life-span. This is thus a means for Microsoft to make a little more money. It is impossible, after all, to go bankrupt when you're on the top.
