Validation of Windows refused by Microsoft

About two weeks ago, a window opened on my computer screen telling me that the version of Windows that I run with (Windows 7 Home Premium x64) was not a genuine one. I had either to reinstall Windows or to buy a genuine version of Windows.

Here are all the things I had to do to have Windows being recognized as genuine. The original text on my blog is in french but I thing that it is possible to understand its automatic translation.
