I let Norton utilities 15 compact my registry. Now my computer will go through most of the boot process then gives me a blue screen of death and crashes. I had Norton back up the registry before compacting and using the windows 7 ultimate OS CD I can get to a point where I can see the registry backups but it will not let me access them. Sent time with Norton support and level one could not do anything because they could not connect to my computer. It took four tries to get the tech to understand that I could not connect to the internet because the computer would not boot up. He sent me to the call back system and they had me download a run Norton bootable recovery tool. Found out this was only for viruses. Can anyone help me rename the corrupted registry and revert back to the backed up registry???? Thank you
