Well after some Weeks of using Windows 7 with the Version that was installed on my Recovery DVD, I received a message that said my Copy would be not genuine.
I had to go through a Martyrdom of typing the original Product Key and sending it to MS and then I had to call some weird Telephone Number and then I had to type lots of Numbers the recorded announcement-lady told me to until Windows finally started without asking me to get Genuine at startup and persistently switching the Background Picture to a Black Screen and „This Copy of Windows is not genuine“ message.
And so… WHat did I do wrong? WHat can I do to prevent this stuff from happening again?
