Installed per the install thread with Daz loader (thanks). Worked great. Used Seagates Acronis software to clone the drive to a larger drive. Installed new clone, worked for several hours. Installed my DVD burner, turned on machine. It spent a while "preparing your desktop" then blank blue screen with "This copy of windows is not genuine Build 7600". Reinstalled original drive and it seems to be working. What happened? KB971033 not installed, AU turned off. Asus PK5-E mobo. Thanks.
