After removing a virus on a computer I was working on, Windows7 64bit build 7601, I got the message this copy of Windows is not genuine. I know it is and has an OEM key I have reset the WGA key with the CMD C:\Windows\system32>SLMGR /REARM This removed the message on the bottom right of the screen Going into system, properties it tells me windows needs to be activated When I click activate it tells me the key is incorrect What should I do now as this will only last for about 30 days then the message will return
