Dear All,
Windows 7 Professional has been installed and activated in my Laptop. I'm using it since last two years. Few days before I installed Windows 2008 Server in the same Laptop. Now it have dual operating system. Windows 2008 is not activated because I need to purchase licence for the same.
Today I change the system date and when I restart my Laptop, I saw the license of Windows 7 professional was deactivated and showing me "This copy of windows is not genuine".
I had OEM license for Windows 7 professional installed in my laptop, unfortunately I have no documents and product key for the same.
please help me to recover the previous product id of windows 7 professional.
Regards,
Anand
