Hi guys, Im quite new at this kinda thing. Ive installed the Windows 7 at my laptop, all went fine. But I didnt use any loader or used any serial key. I just installed and use it. After a week or so, the desktop went black and this message appear: Windows 7 Build 7600 This copy of Windows is not genuine My question is: can I solve this or do I have to reinstall windows? Because, honestly, would be a pain in the ass to backup everything and reinstall al the softwares again. So. Am I in trouble?
