 Hi,I have a Dell Vostro with Vista Home Premium.  I reinstalled the OS.Now, I can't use the computer.  At login screen it shows the "Windows Activation" and indicates that the Windows Vista product key is invalid.But, all I did was reinstall from the DVD.How do I fix this?Thank you for your time.    Hi nohellphiccup, You should have an blue sticker, stuck to your system case with your product key on it.
