So I fell asleep and left my computer on, I'm using Windows 7 Ultimate x64 on a brand new not even week old custom built computer. And when I fell asleep Windows updated, it applied the update that disables pirated windows (update kb71033) AND it installed service pack 1. I managed to restore back to when I didn't have SP1, now I don't have it anymore, but every time I log in computer bottom of the screen "Windows 7 Build 7600. This copy of Windows is not genuine". What do I do? I tried Windows Loader by Daz, except under "profile" there's a list of brands but obviously being on a custom built computer... i don't have a brand. I hit "install" anyways and nothing happened. Can I reinstall Windows 7?
