How to fix This copy of Windows is Not Genuine message?
I have Windows 7 Professional installed on my computer. This was working perfectly fine, until I got this error message from Windows that the copy of my operating system is not genuine, after installing some updates.
It fails to validate also. I bought this with a preloaded Windows 7 Professional,and my whole desktop screen turns black. How can I fix this?
