'Flat Belly' wrote in message. Hi, I recently bought a Windows 7 Ultimate 32/64 retail copy through an auction website. The package and everything else seemed legit to me and both the installation and the activation of the OS were succeful. However, three days later, after the download and installation of scheduled updates, my Windows suddenly got a watermark 'This copy of Windows is not genuine'. The activation status was gone. Now, when I'm trying to activate my Windows again, the system says 'The product key you typed has been blocked from use by Microsoft'.

The activation via phone failed, too. Is this Windows copy fake, or there is some other problem I can't figure out? Any help and advice would be very appreciated. Thanks in advance.
